Problems With Soap Bubble Suds in Bosch Dishwasher—No Solution Yet

I was born in 1948 and spent most of my career as a self-employed computer trouble shooter for Unix systems.

Most people who move into the over 55 retirement community where we now live either custom order their home or buy something used from someone leaving. Our situation was a little different: we bought a house where someone was unable to complete the purchase. They had never moved in, never even paid anything but a deposit, but they had specified things like floor coverings and appliances.

We liked the model of the home and the location was perfect. We didn't like their choices in floor coverings, cabinets or appliances, but we felt the location over rode all that so we bought. The first thing we did was rip out half the carpeting they had wanted and replace it with wood, but we left the appliances as they were because we felt we could live with them.

Cheap Dishwasher

The dishwasher was a cheap GE model and was very, very noisy. It didn't do a great job with the dishes and the loudness of it was annoying, but we lived with it for two years until I found out that my nephew and his wife had been living without any dishwasher for a year because they could not afford to buy one. I took that as opportunity and excuse: I wouldn't have to throw away a working piece of equipment (I detest waste like that), my nephew and his wife could escape the drudgery of washing dishes by hand for a family of four, and we'd buy something quieter and better.

By the way, my nephew has four screeching birds that live in their kitchen. The noise from the GE would be nearly inaudible compared to those birds.

Low End

So we bought a low end Bosch dishwasher. We saw no need to go for the fancier models; its just the two of us and as we eat lightly and simply, so we don't normally have much to wash anyway. Most of the fancy stuff is just more complicated controls for convenience features we don't need; we felt the low end was fine.

"Low End" with Bosch is still close to a $600 purchase. We picked the SHE33M02UC because it was well reviewed at Consumer Reports and because I was able to get a good deal on it from one of my customers who sells Bosch and other higher end products. I brought it home, called my nephew to come help and by the end of the day we both had working dishwashers. His wife was far beyond happy that day, though my wife kept apologizing to her about the noise.

Even if they didn't have screeching birds, I think she would not have cared if it sounded like a jet taking off. She was just happy that they would not be standing over that sink for hours.

The Sound Of Silence

We were very impressed by how quiet the Bosch was. Compared to the GE, it almost seemed to make no noise at all. But we soon realized that all was not well in dishwasher land.

Remove from dishwasher, fill with water, many soap bubbles

Remove from dishwasher, fill with water, many soap bubbles

Dump that water, refill. bubbles gone.

Dump that water, refill. bubbles gone.

Tiny Bubbles Make Me Feel Blue

One of our complaints about the GE was that it didn't seem to wash very well. We happen to be big water drinkers and we filter our tap water rather than contributing to more pollution with bottled water. We had noticed with the GE that we'd see little soap bubbles if we didn't rinse our glasses before using them. We could also taste it - we wouldn't have noticed it with milk or juice, but it stood out with filtered water.

That was another thing my wife kept apologizing for. I could see the look in my nephew's wife eyes: a few tiny soap bubbles were not anything she cared about at that point. A little soap is better than a backache. We had post-rinsed, she could do the same.

They're B-a-a-ck!

We had expected that problem to disappear with the Bosch, but it did not.

Wow. That WAS a surprise. Were we doing something wrong? I asked my appliance dealer and he suggested several possibilities.

Things that can cause left over soap

Blocked drain

If the soap can't drain, all the rinsing in the world is not going to help. Could I have messed up the installation or or kinked the drain hose?

Well, the Bosch drain hose is very hard to screw up. It is attached to the side of the unit and almost impossible to kink. Still, I pulled it out and double checked and also interrupted the cycle to confirm that it was able to drain everything out.

Dishwater Soap

If you happen to squirt any dish or hand detergent onto dishes waiting in the sink for later loading into the dishwasher, you can create too many suds for the dishwasher to handle. Dish and hand soap is designed to suds up, dishwasher soap is not. You'd see that it is unable to drain away all those suds if you opened it up during the cycle.

We made sure that didn't happen.

Not hot enough

We always run the hot water before doing the dishes and we don't keep our water heater turned down low. That goes against most advice for saving money, but my fear is of bacteria growing in the tank, especially as we don't use much hot water. It sits there a long time, I want it hot to kill stuff off.

Too much soap, too much Jet Dry with soft water

We tried using less and less soap and got down to less than a half teaspoon - still had bubbles. We tried it with less Jet Dry, no Jet Dry and more Jet Dry. No change whatsoever.

Built up soap

Here the idea is that your past sins are still haunting you. Soap residue has built up everywhere and is reintroduced at every wash. The suggested solution is to run through a few cycles with no soap and white vinegar.

I used up a gallon and a half of white vinegar in a dozen cycles with no soap and nothing changed.

The Internet

I turned to Google for help. Unfortunately, if you search for soap film and dishwashers, you are more apt to find suggestions for dealing with hard water deposits and etching than left over soap that causes bubbles. If you search for bubbles instead of film, you find problems with sudsing and they all talk about the same things we had already tried.

I did find one person who claimed that the problem can come from dishes being too clean. His theory is that the detergent needs grease and grime to stick to and that without it, it can't ever really wash away.

If that is our problem, we'll be living with it forever because we don't eat greasy foods. We hardly ever eat meat at all. Do I have to add grease to my dishwasher? That seems unlikely.


So, one month shy of our warranty expiration, we called Bosch. They checked everything over and told us that our soap was the culprit. We've been using Trader Joe's; Bosch recommended Electrasol (now called Quantum Finish).

Fine. If that's what we have to do, that's what we have to do. He left us samples; we tried it.

There were even more soap bubbles. Sheesh!

Back to Google

I went back to Google and searched more. I found someone who said they had this problem but had improved it with 7th Generation detergent. We use their clothes washer detergent now, so we will try that, but really wonder whether this is unavoidable.

We never had this problem back in our old home. The major difference is that we had an older dishwasher not designed to save water. I had put that puppy in decades ago. I suspect that old model may have wasted a lot of rinse water, but didn't leave soap on our dishes. We used Trader Joe's there, so that's the same.


I wonder if other people have this problem and just haven't noticed it. If we did not drink filtered tap water, we would not have noticed. You expect milk and juice to have bubbles and anything but water will mask any taste. Even tap water will mask it if it has a noticeable amount of chlorine.

Maybe people have the same problem and do not know it?

Bosch Redux

We have Bosch coming back for another look-see. I honestly don't feel hopeful about resolving this.

If the problem is that our water is too soft (which is actually a silly phrase because water either has mineral content or it does not), the most often repeated advice is less soap. I don't know how little we can use and still hope to clean anything. However, we will keep trying and we'll see what happens.

I'll update this if I get any new information.

I have no idea, sorry.

sal1965 on May 19, 2020:

I did a thorough cleaning of the tub, filter, and screen. I replaced the washer blades last year. I just did another regular wash. There was no soap sitting in the tub.

So I decided to test it and took everything out of the bottom rack and left glasses in the top rack. Ran it for about 10 minutes, canceled the cycle and there was soap foam on the bottom.

Can I assume that residual detergent is sitting in the drain well and foaming back up? I use lemi-shine packs.

Tony Lawrence (author) from SE MA on May 18, 2020:

Have you checked your drain filter recently? Many people don't realize that they have this and it will fill up over the years and trap awful smelling stuff, and soap..

sal1965 on May 17, 2020:

Glad I found this page.

I have a similar problem with my 6-year-old Whirlpool gold but in a different way.

When I run a full cycle there is no soap at the bottom of my dishwasher, but our dishes had that funky smell, so I did a 1-hour wash for about 10 minutes to rinse them, then cancel the cycle, that is when the bottom is filled suds. With no soap in the dispenser and the rinse cycle not yet started, where would that soap be coming from?

It is draining fine, the filters are clean

Could the funky smell becoming from residual soap or rinse agent which is causing the soap to appear in the tub or do I look elsewhere?

Tony Lawrence (author) from SE MA on March 13, 2020:

Yes, I am also frustrated. We bought a new Bosch since then and we use very small amounts of 7th Generation detergent, but we still have to run an Express cycle with no soap after every wash.

We’ve given up and simply accept this as it is.

LemonKiss on March 11, 2020:

I LOATHE soap bubbles in my glassware and dishes. I try using the smallest amount of 7th Generation soap possible in my Bosch, but there are always bubbles. My husband thinks I am crazy and paranoid, but god dang I don't want to drink chemical soap. Frustrated.

Apartment Dweller on November 10, 2019:

Okay, I know this article began long ago, but until I found this, I did not find anything else describing the soap bubbles forming when clean glasses are filled with water.

I live in an apartment and this dishwasher is a Hotpoint (GE), which replaced one that had quit working after years, but hadn't had this problem. Initially, I thought it was working (though is VERY loud, runs a LONG time), the dishes coming out APPEARING clean.

I don't know when I first realized there were foaming bubbles, whether tasting it first, then seeing, then trying another glass and seeing foam. I began checking everything from the dishwasher, apparently having been drinking soap and serving to guests.

rosarita on July 27, 2019:

I'm so glad I found this post before I called for service. I approached my DW sudsing problem with logic. The suds must be coming from somewhere. I tested the drain, it was not backing up. I'm not adding soap so I looked at the rinse agent. I'm using Finish which is what Bosch recommends for my machine. I put one drop of finish into a glass, added water and it foamed like tap beer. I reset the machine to turn off the rinse aide, and then I cleaned my machine. I did a cycle, had a few bubble, not too many. drained that and cycled it again, this time no bubble. I ran a quick wash all the way and checked a few times, no suds. I thought I had it licked. The next morning, I once again put it into a cycle without adding soap and I had a tub full of suds.

I decided that even tho I had turned the feature off, logic dictated that the only sudsing agent in the machine was the rinse agent. So I drained the reservoir, which was not easy. They don't give you an option to drain it. I took the straw from a can of compressed air, fitted it to a 10 cc syringe and made an airtight seal with putty, I was able to thread that into the reservoir and suction out the liquid. If anyone tries this, get the end of your plastic straw to curve a bit so it will slide into the bottom of the reservoir. Stand the door up as much as you can with your hands still inside and suck out the last bit with the syringe. After doing that, I reset the machine to highest dispenser setting and got an 'refill rinse agent' red light, so its empty or pretty close. Then I turned it off again. After that exercise I cleaned up as best I could, and the next load I ran was terribly sudsy because you just can't wipe that stuff up, it sticks to the sides. But after that cycle, and cleaning it out one more time, I stopped getting suds.

The next morning when I ran a cycle to check, I also did not get suds. On previous tries, it would not suds after several cycles but it would suds again in the morning. My conclusion is that there is a leak in the dispenser. Hence, the first cycle I ran in the morning was sudsy (since the machine sat overnight) but subsequent cycles during the day were not (because its a slow leak so not enough got out...there was always a little suds with the first rinse and that doesn't happen anymore).

This all took place over a three day period, each day I would get it clean, run no suds cycles and the next morning, the suds would be back. It was only after I drained the reservoir that it finally stopped sudsing up.

I bought new eco friendly detergent and started using the machine again without any rinse aide and my dishes and glasses came out just fine. I also bought eco friendly rinse agent but I'm going to try not to use it. It also makes suds. I do believe it must be leaking some into the machine, somehow, and I'm out of warranty so would rather not pay for repair. It could also be a flaw in the programming that dispenses the stuff. If I do decide to use it, I will fix a paper towel to the area underneath the dispenser so if it leaks, it should show on the towel...and I can clean up most of it maybe.

I know this might not help many of the people here, but if you are using regular rinse aid, that is very likely the cause of the sudsing in your tub. When I ran my first load with my new soap, I opened it during the wash cycle, and there were no suds. I was concerned I didn't put in enough soap but the dishes were spotless. So I really believe that at least some of you with sudsing problems should look at your rinse aide, it just might be the culprit. And consider that Bosch machines may have a slow leak in the rinse aide reservoir.

@fig4159: I tried that soap and no luck, I still have bubbles.

fig4159 on September 12, 2018:

bommerts Yes, that's the one, though I can't guarantee the same results. I'm sure water composition/hardness has a lot to do with it. All I drink is water, and lots of it, and I'm very sensitive to taste/odors. If there was residue, or bubbles, I'd be first to notice. To double check, I rinsed the entire load: NO BUBBLES.

Tony Lawrence (author) from SE MA on September 10, 2018:

Detergent doesn’t help. Doesn’t matter.

bommerts on September 10, 2018:

@fig4159: Is this the detergent you're referring to?


fig4159 on September 02, 2018:

NO suds, bubbles OR soap residue

We've now had our Bosch (SGX68U55UC} long enough to be sure: we have no bubbles, residue, or soapy taste. The local utility states the water is moderately hard @ 4-6 ppm. This model does have a built-in water softener, to which I add generic salt (https://amzn.to/2BUbzFf). I also add white vinegar to the rinse dispenser.

I've been using "For The Love of the Planet's 2X Ultra High Efficiency WAVE Natural Auto Dishwasher Gel" since the machine was installed and almost everything* has come out clean (except some baked on cinnamon powder).

Hope this helps someone, although as always, YMMV.

laguna-greg on July 28, 2018:

Hi All, thanks so much for the excellent and helpful discussion. I installed a high-end Bosch dishwasher in my new home in 2012, with excellent results at first. Just 6 months ago, I noticed that dishes were not coming out spotless as they had been especially the glassware, and just recently noticed the dreaded bubbly suds in the bottom of the tub at the end of the cycle as have so many others. All the other conditions check out fine e.g.tub and filter clean, good water pressure/temp, clear sink drain, very good water condition, etc. So it's the machine, as "Washtub" suggests below! Oy...

I am going to try to do a super cleaning cycle as other have suggested, and tinker with the chemicals a bit to see if it won't help. Extra rinse cycles do seem to reduce or eliminate the suds and residue, but is this really what technology has reduced us to? I am hoping a really high end machine like a Miele could do a better job with this, but I'm going to explore that thoroughly before even thinking about replacing the machine.

If things get better I'll let you all know!

Kirolo on July 17, 2018:

I have a GE Cafe dishwasher. We use the built-in bottle washer for glasses and bottles. We notice soapy water when we fill up our glasses. Running a rinse cycle after the wash cycle helps some but not entirely! Has anyone found a true fix for this??

fig4159 on July 06, 2018:

I'd be willing to bet that this problem is caused by chemicals in the detergent.

I'm buying a new dishwasher this week, so I'll find out soon enough if I'm right. I either make my own cleaners, or use "green" cleaners that are highly rated by EWG.org.

I'll follow this post in case anyone has questions, and will post back once I've tested my theory.

washtub on June 20, 2018:

Hello All. I am a retired designer for home appliances. Most big appliance companies hire design contractors to fulfil new product needs, very few have staff engineers. That's why there is so many issues that follow a new appliance to market. As far as the suds issue, Bosch may be the worst. They make a good machine, but it fails the customer based on flawed science. Many dishwashers leave suds behind, so this blog will address all models. First, if you are experiencing suds residue in your dishware, do not ignore it. Soap sufficants are toxic to humans after prolonged exposure, and can result in gastric illnesses and cancer. I would recommend to immediately check all future loads and rinse accordingly until you have arrested the situation. The main issue with residual suds on dishware comes from 3 possible scenarios. First, most dishwasher soap pods are engineered products, and therefore react differently to a wide range of environments. If you have soft water, you are more inclined to have a suds issue. Slow drains are another relevant issue, and so is low water pressure and temperature. The prevailing reason for residual suds on dishware is; the system is not evacuating the soap out of the tub cavity before the rinse process begins. In most cases you cannot correct this problem. Why? well, because the logic circuits are programed with firmware that have a pre-set of instructions that cannot be altered without a proprietary computer device. With Bosch there is also the obstacle of their sprayer spindle. Bosch uses a 3-hole (X2) sweep arm technology on each sprayer spindle, which in most cases cannot reach or deliver fresh water deep enough into cups and glasses, and may bypass some areas on other items.Until dishwasher manufactures incorporate a final power rinse to protect consumers, suds will remain an issue. 2 caveats are seen here: manufactures can easily reprogram older machines for a low cost to purge remaining tub soap, and administer a final fresh water power rinse. It will bruise their green agenda and ego however, returning overall dishwasher operating costs back to pre-2008 levels. But for now, Bosch will come out check your machine and counsel you that this is an unusual issue, for $129 service call and $2 per minute. Please write the Consumer Product Safety Commision with your story...

Please read other comments.

Omega from USA on May 26, 2018:

I am having these same type symptoms and have also become frustrated trying to find a solution using Google. I have wasted so much food and drink after filling what I thought was a clean cup, or pot, or plate. I cracked an egg into a saucer yesterday morning in order to make a "perfect fried egg" lol only to find tiny soap bubbles and then one huge soap bubble in the egg. So another Saturday spent trying to figure this out. I am most interested in any solutions or work-arounds that you would be kind enough to share.

I'll check back soon, right now I have a wet vac full of rinse aid/flush water mix to get back to

Tony Lawrence (author) from SE MA on May 09, 2018:

No, no change.

acowann on May 09, 2018:

I recently moved into an apartment that has a Bosch dishwasher with the same issue. Thank you from this post Tony! It's nice to know I'm not alone in this problem. Did you ever get to try out the oil idea? Just curious if you thought it helped.

bommerts on February 09, 2018:

Quick follow up on the TSP. No luck. Still have bubbles. The quest continues....

CRoger1KS on February 09, 2018:

I recently started having soap bubbles in the bottom of my six-year-old Kenmore Elite (made by Bosch) dishwasher. Last night I timed the pots-and-pans cycle. It is only running for an hour. It used to run for a minimum of 90 minutes. The only cycle that is supposed to take 60 minutes is fast wash. I guess I am going to have to run 2 cycles to get everything rinsed properly.

MekaBelle on December 22, 2017:

Soap suds in the bottom of my Bosch DW started appearing a few days ago. Reading all comments (thank you) I decided to remove the screen and filter. I found stuff in the bottom (gross) and removed debris. Then I flipped the screen part over and found "lint" around the edges. I found more lint inside the trap cylinder as well. I suspect the lint stuff is leftover plastic bits from the Kirkland dishwasher pods I recently switched to. Going back to powder soap and see if that eliminates the lint stuff.

GreatLifeFitBev on September 06, 2017:

I'm so glad to hear I'm not the only one going crazy! All the sudden last week my BOSCH Dishwasher had bubbles in the bottom. I've run it without water. I've added oil. I've added vinegar (now my hands smell like a salad). I've run it about 8 + times without soap. I've run it with Afresh Dishwasher Cleaner. Each time scooped out the bubbles, cleaned the bottom and STILL Have Bubbles! Called Bosch - they said need to have a tech come out. What is he going to tell me the same thing? What is causing it to happen. I haven't changed a thing! I use Finish. I have well water and a water softener. I've cleaned out the trap at the bottom. No one seems to know why all the sudden out of the blue is this happening. Then to call for a service call for $140 ugh!

bommerts on July 13, 2017:

Yesterday I received and tried the TSP that we bought from the link I posted above. I added 1/2 tsp of TSP on top of a full block of a Finish Powerball tab. After running a full normal cycle, we were shocked: The bubbles were down about 80%.

Today we're trying another 1/2 tsp of TSP but this time with 1 tbsp of cheap lemon powder detergent. Will follow up with how well it works or not.

So far though, the TSP seems to have reduced the bubbles greatly. So much so that we thought it was acceptable to just drink out of the glasses as-is after a wash.

Tony Lawrence (author) from SE MA on July 10, 2017:

Thanks for that article. I might try that.

bommerts on July 10, 2017:

Wow - I thought I was the only one with this problem.

Had a 5 year old Bosch. Soap bubbles just like you.

To solve the problem, we replaced it 2 weeks ago with a top of the line Bosch. Same problem still.

We do the additional light wash cycle w/o soap, too, to rinse off the bubbles.

I think you're on to something with the lack of phosphates.

Have you tried adding it back in?


From this article:


Tony Lawrence (author) from SE MA on June 20, 2017:

Filters of course need maintenance, but that's not the solution here. New, clean machines exhibit the same issue. It's the low water use that doesn't rinse enough.

TedAP on June 19, 2017:

I found this page looking for a solution for the soap left in the dishwasher problem. I have a lower end Bosch, purchased and installed about a year ago. It's just recently started leaving soap in the bottom of the machine.

Well, after staring at the dishwasher for a few minutes, I wondered about the stainless steel strainer at the bottom of the machine and the condition of it.

Upon removal of said strainer, I discovered a very fine mesh strainer as well. The strainer was completely clogged as was the rectangular strainer.

I've now cleaned both of them and running another cycle of the machine. (some time later...) This seems to have fixed the problem on my dishwasher.

So, if you have any types of filters or strainers on your particular machine on the drain system, I suggest removing them and cleaning them thoroughly.

Tony Lawrence (author) from SE MA on March 30, 2017:

We bought a new Bosch, more expensive model.

Same problem. Same fix - extra cycle without soap.

Appalbarry on November 01, 2016:

Three years later, the Bosch is still going - we hadn't realized how long we've had it - something like seven or eight years. We've stayed with liquid soap, filling about half full, and seem to be avoiding the build up issue.

I've replaced both pumps, and have become pretty talented at disassembling and reassembling the thing.

The only problem that seems to have emerged is a strange one - periodically it needs a massive clean out or dishes just don't get clean. It's almost like something has gone kaput and is letting food bits into the works.

The one specific recurring problem is that the top rack spray arm is constantly getting clogged - usually a grain of rice or something similar gets stuck in the hole at the outside end of the arm, and what ever is in that rack just doesn't get washed properly.

The only solution is to take of the spray arm and shake it madly in all directions until the offending bit falls out.

Tony Lawrence (author) from SE MA on November 01, 2016:

Yes, it can be maddening. The extra cycle does fix it, but I hate wasting that water.

vgs1895 on October 31, 2016:

OH MY GOODNESS!!! I thought ***I*** was the only one with this problem. I had an older Bosch and loved it. I got this one a month or so ago and have been going CRAZY with the suds. THANK YOU!!!!!! Even though the problem isn't solved, at least I know it's not something I am doing wrong!

Selny1 on February 05, 2016:

I am so glad I found this thread, and realize that I am not crazy! My Bosch dishwasher was installed in 2004, and I have never had a problem with it until a couple of weeks ago. I started the dishwasher in the morning around 9:00 am, and got a text from my sitter at 2:00 pm that the dishwasher was still running!! I had her pop the door open to stop it, and when she looked inside, the bottom was full of thick suds. After removing the dishes to hand wash (yuck!), I tried running the washer on a rinse cycle which did complete and seemed to have cleared the suds. I then tried running a Regular cycle on the empty dishwasher with no soap pellet, and, again, the cycle was still running over 3 hours later! And, the bottom was full of thick suds again. Another Rinse and Hold cycle completed on its own, and the suds seemed to be gone. This time I called my appliance repairman (who is a certified Bosch repairman), and he said to throw 3-4 Tablespoons of vegetable oil into the bottom of the dishwasher and let it run through a Delicate/Hold (since it is a shorter cycle & would not waste as much water)with no dishes (he said we were putting the dishes in too clean), and that this would break the suds down. The cycle completed and there were hardly any suds in the bottom. Celebrating ensued, but, alas, was short-lived. The next load I washed with dishes (which I left dirty, per the repairman's instructions)' and the soap pellet, resulted in a non stopping Regular cycle with thick suds again in the bottom. Next call to the repairman resulted in him coming out, testing my Jet-Dry and telling me I had a 'bad batch' of Jet-Dry, and that a lot of repairmen had been encountering this problem. He suggested I call the company, and find out if my recently opened bottle of Jet-Dry was part of the bad lot. He also used a syringe to suck out the remaining Jet-Dry in my dispenser. I called the company, and was told that the Jet-Dry I had was not part of the problem batch. And, since I used Finish dishwasher pellets (which contain a little Jet-Dry) and we have soft water, that I did not need to use any Jet-Dry at all in the rinse aid dispenser. To wrap it up, the light has been on to refill the rinse aid dispenser for at least a dozen loads now, and I actually have been using Mrs. Meyers dishwashing pellets to avoid any Jet- Dry in the machine. The dishwasher is still not completing a cycle on its own, and the bottom is full of suds when I pop the door open. I have to use the Cancel/Drain buttons every time, then run one (or two) Rinse/Hold cycles to clean the soap off the dishes. Of course, they do not dry properly. After another call to the repairman where he said that all he could do would be to replace the Jet-Dry dispenser (which I am not even using anymore), and that our water must be too soft, and that we weren't leaving the dishes dirty enough, I gave up and use my 2-cycle system. The water, soap pellets, and Jet-Dry have been the same ones used in the dishwasher since it was installed in 2004, and there has never been this kind of problem until recently! The repairman insists that it isn't the machine itself; the Jet-Dry people insist it isn't their products, but something is wrong! Very frustrating!

Tony Lawrence (author) from SE MA on November 07, 2015:

It is annoying and it drove me crazy also.

catsrule1962 on November 06, 2015:

I have been hand-rinsing my clean dishes for several years now and have an LG dishwasher. I truly appreciate the fact that you started this blog, as it has made me feel more "sane". Like you, I wonder how many people never pay attention to their dishes and are drinking soap suds. I am going to try several of the things you have tried, starting with the vinegar washes to clean out the suds. I will also switch to powder detergent and greatly reduce the amount of detergent that I use. Thank you SO much for the time you have taken to keep up with this blog! It will help me tremendously to get rid of the suds and not have to hand rinse and air-dry after every load washed. Thank you, again!!

Tony Lawrence (author) from SE MA on May 27, 2015:

No, I don't think so because the extra rinse does fix it.

Gloria Novo on May 26, 2015:

Same problem....all that's left is the water going into the dishwasher. Could it be something in the water coming from the treatment facility?Anyone with artesian well water drinking bubbles? Actually I notice it in my washing machine with he premeasured detergent.

Tony Lawrence (author) from SE MA on April 15, 2013:

We still run the extra no soap quick wash, and half filling the regular wash as you do. This seems to work well for us, so I don't think Peter's theory applies to our problem, though it may for someone else.

A followup from our posts two months ago: After we ran multiple empty loads to clean out everything that had gunked up the machine, we set to work finishing off a big box of Finish All-in-1 Gel Pacs.

In retrospect, those were a dumb purchase, as Vancouver has insanely soft water, and the gel pak has too much soap for us and can't really be divided.

Plus the stupid things stick to each other in the box....

For the last two months I ran an Auto cycle with a gel pak of soap, followed by a Quick wash with no soap. We're ignoring JetDry right now because the Gel Pacs had it built in..

This has actually seemed to do a good job on everything.

We've now switched back to powder, (Cascade I believe) about half filling the soap dish, still with no Jet Dry. It seems to be working pretty well.

It's worth noting that our e-mail to Bosch was never answered.

Interesting thought..

Peter on April 15, 2013:

Soaps aren't the only thing that will form "bubbles" in water. Proteins, larger peptides, and other cellular components may do so as well. A possible source of such material may be from microbial colonization of surfaces in the dishwasher or water piping, often referred to as biofilms.

Tony Lawrence (author) from SE MA on April 14, 2013:

Nope. We've been through all that and more. We don't use any Jet Dry or anything like it.

DertRhodes on April 13, 2013:

if you're actually seeing soap suds then either hand soap/dish soap is getting into the unit from prewashing your dishes or washing your hands over your dishes and putting the dishes in your Dishwasher. If this is the case, stop doing it obviously.

This can also happen from Jet dry. Dishwasher detergant can NOT suds no matter how much you put in but jet dry can. Start a cycle and pour a cup of white vinegar into the bottom once it fills, let it run for about 3 or 4 minutes and this will get rid of all the suds. Cancel the cycle or let it run through the rest of the cycle. Start another cycle and don't put anything inside. If at the end of the cycle you have suds, then you have a problem with your dispenser putting too much rinse aid out. You can remove the rinse agent cap and turn the dial down, the number 1 is the lowest and 6 is the highest so put it to 1 or so until you figure out if this works. If so then great, if not and it still sudses with no dishes or anything then you need to replace your dispenser.

Use less soap..

Appalbarry on February 10, 2013:

Bosch SHE55M (see above) - after yesterday's mega clean, I ran a full load - the usual mix of pots and pans, plates, and endless coffee cups.

WOW! I had no idea how bad things were. China and glassware SQUEAKS it's so clean. A cup of coffee no longer has a vague (or lately not so vague) soapy taste. Silverware gleams. This machine is running like brand new - and there are NO suds in the bottom of the machine.

I guess now it's a game of waiting and watching too see how long it will before another multiple cleaning cycle is needed.

Tony Lawrence (author) from SE MA on February 09, 2013:

Please do let us know.

Appalbarry on February 09, 2013:

Bosch SHE55M (see above) Today I unhooked the drain hose, pointed it into a bucket, and ran a Quick Wash load of dishes with a gel pack of soap. The Bosch emptied three times (I believe). Each of these was icky grey water - I would have expected the final rinse to be close to clean water?

I then ran the Quick Wash cycle three more times, with no soap. The Rinse agent light had been on for at least half dozen cycles so I'm thinking it should have been empty. Even though I was running soapless, with just washed dishes, the water coming out wasn't clear, not even close, until after two extra runs.

Then I ran a Full Pot Scrubber Cycle - and found SOAP bubbles in the water coming out of the drain hose! Ran it a second time and seem to be getting clear water.

I do know that almost since we got this unit, we've noticed that the water well under the strainers always seemed to have grubby water in it. I trusted that Bosch's design was good, and that this was normal. In retrospect maybe not.

In any event, I'm thinking that we're suffering build up inside of the dishwasher plumbing. I'm thinking that different cycles allow build up in different places. I'm thinking that Bosch has some serious design problems.

In the interest of science, I'm going to run one more soapless, clean cycle, then see what happens with the next regular load.

Appalbarry on February 09, 2013:

Bosch SHE55M. Same issue. Three years old. Lovely QUIET machine, but this has me really irritated.

Tony Lawrence (author) from SE MA on January 27, 2013:

I don't know, but it can't hurt to try.

Autumn on January 27, 2013:

Thanks for the infor. These past three weeks, our Bosch dishwasher had the suds problem. I always do extra Quick wash after normal cycle, but now it stills has lots of suds even though I used two- time extra of Quick wash cycle. Shall I try the Cleanser which somebody has mentioned ?

Tony Lawrence (author) from SE MA on December 30, 2012:

My feeling is that all new washers will do this. We have settled on using very little soap and always following up with a light wash without soap. That is working for us.

Sharon on December 29, 2012:

WOW! I have been through the same experiences and you have Pcunix with my Bosch dishwasher. I have heard it all, done it all, with and with out soap, with and without rinse agent, have used dishwasher cleaners, have used vinegar, run numerous cycles with water only AND I STILL HAVE SUDS!!!!!!!!!!!! I have had numerous service visits- each time with new advice. I am in the process of seeing if I can have the machine replaced under my extended warranty. Thank heaven I bought one. I will let you know what happens.

Tony Lawrence (author) from SE MA on November 24, 2012:

After 2 years? I don't think so :-)

Jj on November 24, 2012:

I tried Jet dry for the first time three days ago and since then have been running the dishwasher empty continuously to get rid of the bubbles!!! Even if you don't use it anymore, the rinse aid is the problem if you have bubbles at the end of the cycle. Do what was suggested and suction out the dispenser. There may be some in there.

Dale on November 16, 2012:

I am very pleased to find this string of comments. We have the Kitchen-aid model mentioned above and have the same problems as everyone else. We have tried all the same solutions with no resolution. To top it off, the bubbles back up and make the washer leak onto our wood laminate floor. This problem appears to be widespread enough that maybe we should consider contacting the consumer protection agency and/the news media. This could also be considered a heath hazard. I think these dishwasher makers may be using similar engineering and they need to be called on to be accountable for fixing this problem!

Tony Lawrence (author) from SE MA on November 05, 2012:

We never use rinse agents but still have the bubbles.

rbc on November 05, 2012:

Had tried many of above options. Finally used a syringe and paper towels to remove all of the "Finish jet-dry" rinse agent (16 OZ bottle SKU 51700 78826) from the rinse agent dispenser of my Bosch dishwasher so that it was bone-dry, then ran machine on rinse cycle a few more times and now when I open the dishwasher, I no longer have a white soap film on my dark dishes (such as black plastic spatulas, dark gray non-stick pans, etc.). They now look really clean! My only guess is that the chemicals in this brand of Finish, mixed with the chemicals in the Cascade I am using ("Cascade Complete" which in tiny print on the label says "with Pure Rinse Formula"... SKU 337000 33840) for the 75oz size, are what produced the bubbles that were left over after each cycle.

Tony Lawrence (author) from SE MA on October 31, 2012:

I don't have anything new to add. As noted above, rinse aid didn't help us and changing soap brands did not either. For us, only the extra wash with no soap makes any difference.

Doug in CA on October 30, 2012:

Our Bosch is brand new and never severe subs problem was never present in the old machine. I have been doing pots setting twice foreach load to get it clean. Does the rinse aid have any use? What about the idea of putting the soup in and not closing the soap container door - I think my old dishwasher soap container didn't really close.

What about filling it with a few extra gallons of water before it starts? I could care less about waste of water. What is the best soap and or rinse agent? Finish doesn't seem to work.

Tony Lawrence (author) from SE MA on September 25, 2012:

Yes,that what we've been doing for two years now. Waste of water but it works.

LAFace on September 25, 2012:

Just a great thread.. and here i thought it was just me! thanks for the ideas, going to try the additional quick wash/rinse

Tony Lawrence (author) from SE MA on July 11, 2012:

I have not and know nothing about that model.

Lisa on July 11, 2012:

One more question---has anyone tried the detergents with phosphates that can still be obtained via the internet? Or is this solely a low-water issue?

Lisa on July 11, 2012:

But what about the non Energy Star compliant dishwashers, such as the KitchenAid KUDS30SXWH?

Tony Lawrence (author) from SE MA on July 10, 2012:

No. I don't think there is such a beast.

Lisa on July 10, 2012:

I'm ready to turn in our brand new Bosch for a model that doesn't leave soap residue. Any suggestions for new models that clean dishes well without leaving foamy bubble residue in a glass of water? Thanks to all for their informative comments.

Tony Lawrence (author) from SE MA on May 25, 2012:

Drain hose kink is possible, of course..

Ann on May 25, 2012:

I have a Bosch as well and my dishwasher is about 16 years old. About a year ago I started having the problem with the bubbles. Service man came out and told me to use the vinegar, that isn't working. Yesterday I tried vinegar and baking soda to no avail still getting bubbles. HELP

demi on May 18, 2012:

Were you able to try out Misslee's suggestion ...

CCalde on May 01, 2012:

Have a 2003 top of the line Bosch and it does the same thing. I read somewhere that the government mandated that a certain chemical be removed from dishwasher detergents last year. Iv'e been rinsing the glasses for years before drinking but just recently noticed that there is a small amount of white film being left behind in the bottom of the tub as well which is something new, everything was always very clean until now! We also use very little soap per wash since getting the Bosch but something strange is going on. I have excellent water to begin with too. I thought it was the jet dry causing the bubbles and just needed to be rinsed off but now that I am getting the white residue I am thinking different.

Tony Lawrence (author) from SE MA on April 19, 2012:

Sudden change like that could be something broken - possibly even just an obstruction in the drain hose that prevents it from draining quickly enough. I would ask that they look into that.

Angi on April 18, 2012:

Okay, so here is my problem... Posting this here because this is the closest I have been able to find on our issue.

First of all, my husband is military, and we live in on post housing. The appliances we have are very basic, and don't get to choose what we get, or replace them. Any way, around Christmas, when making spaghetti for dinner, upon draining the noodles, I noticed there were bubbles in them. I was confused at first, and rinsed them thurally, the bubbles had gone, but there was CLEARLY a rainbow film engulfing the noodles, the kind of rainbow film you see, and just KNOW it's soap. So I tested one, and it tasted god awful! Definitely soapy! Needless to say I did not feed this to my family, but ever since, there has been soap left on our dishes and food.

Thinking it could be our soap, we switched to 7th generation (for both sink washing and dishwasher) but no matter what we did, soap was always present in our food! Thinking it could have possibly been our water supply, we started using our 5 gallon water cooler as a water source when cooking, no avail, obviously the problem lies within the dishes.

I started washing dishes by hand, going light on the soap, and due to paranoia, rinsing each individual dish, t, pan, and spoon for 10 minutes in HOTwater (you can tell my hands have been through hell just looking at them) but we still had the problem! So I cut out soap completely, and ri sea my dishes with vinegar... It worked for awahile, but now the soap infestation is back with a vengeance, even when using vinegar, and the 7th generation. There is so much soap when we cook, it's completely unedibal! I don't serve it when it's obvious, but sometimes you can't tell, or even taste it.... Last night out of paranoia again, I made frozen, neat on the stove PF Changs... I got so sick, I lost my stomach, and when I did... There was soap... So much so, you would think I had rabies! I can't even have my morning coffee! And that is a NO GO for me! What am I supposed to do? I feel helpless here! We thought it was our Teflon pots and pans at first, so we even went out and paid a lot of money for all stainless steel cookware (that have never been in the dishwasher btw) but this problem, no matter what we do, will not go away. Every time I cook, I feel like I am going to poison my family. Cooking was a huge passion of mine, and now I don't even want to step foot in my kitchen.

The kicker is, we can call in for a work order (someone to fix the dishwasher) but, there is nothing they can do unless it's broken, and it's not. Can someone PLEASE help me?!

Tony Lawrence (author) from SE MA on April 17, 2012:

Yes, I sympathise. We do find that running the extra cycle works for us. Waste of water though.

MomMomMom on April 17, 2012:

I purchased a new Bosch diswasher 5 years ago when I bought a new house and have had the same problem as everyone else with sudsing even though I only use a tsp of liquid Cascade. I've had numerous techs look at it and replace parts but to no avail. I even insisted that they replace the whole machine at one point but there is still a layer of suds after it's done washing. I don't use the drying cycle. I wish there was a true solution to this ongoing problem.

Diana on March 26, 2012:

Actually I made a slight mistake - but then I have been eating and drinking soap for quite a while - it's really Finish/Jet. The "cleaner" bottle goes in upside down in the bottom shelf without removing the cap - read directions, I forget exactly - and an empty washer. There are so many Finish products you need to make sure it's the cleaner one - not the additive to regular washing. It empties itself. Two cycles at full hot wash cycle. Then maybe just one short cycle with nothing in the washer. The only place I could find the cleanser was at Target, where Bosch told me to go. Everywhere else just had the many Finish additive types.

I have very hard water too but I am using a little less soap. I've always used Costco brand because of the hard water. I don't pay for my water (condo land). I ran it five times a day for three weeks - but I do pay for the electricity - haven't opened the bill yet.

Tony Lawrence (author) from SE MA on March 25, 2012:

Yeah, we tried the Jet stuff. Did not work for us., but we didn't do a whole bottle!

Thanks for that suggestion.

Diana on March 25, 2012:

I have completed 3 weeks of fixing the suds problem. I did pay a repair company who not only did nothing but gave me the wrong info. After calling Bosch 2 times - I tried this suggestion. Run JET cleaner 2 times full hot cycle. There are many JEt products - make sure you empty the washer and get the plastic bottle that's about 5 inches wide - read the directions and turn it upside down in the washer.Bottom shelf and make sure the arm doesn't hit the plastic bottle. I think I ran the short cycle again a few times. I think (hope)it's back to working. Seems to be the case.

Tony Lawrence (author) from SE MA on March 19, 2012:

If you've just started having problems, you probably DO have a mechanical issue that they might fix.

christina hart on March 19, 2012:

I have had a Bosch dishwasher for three years. Last week, I started noticing lots of suds in the bottom after a regular cycle was completed. I have been using Target brand powder detergent since I bought the dishwasher and I only recently had problems. Was going to call a Bosch technician to diagnose but after reading this string, I decided to forget it. I don't want to waste the money if I have to repair this and that and still have no solution. By the way, our water is hard.

Tony Lawrence (author) from SE MA on March 05, 2012:

Unfortunately, you probably have been.

Diana on March 04, 2012:

My Bosch is 8 years old. Had a lot of problems in the beginning with dirty dishes after the power scrub wash.

Finally added more soap and the dishes wre clean. I took my dirty glasses to the Miele ($2400) showroonm in SF and they came out clean.

I ussually don't open the dishwsher immediately after the cycle. Apparantly the suds have been dissappearing before I opened the washer.

Tonight i opened it right after the cycle ended and - loads of suds. I ran it at least 4 times (no soap) on every other cycle - still suds. I think I have been eating soap for 8 years.

Tony Lawrence (author) from SE MA on February 10, 2012:

Yes, we will.

MissLee on February 10, 2012:

I was quite skeptic myself but it surprisingly has worked and the dishes don't have a vinegar smell either. Let me know if you try it!

Tony Lawrence (author) from SE MA on February 10, 2012:

Thank you, misslee, that is very interesting!

MissLee on February 10, 2012:

I stumbled on this thread as I googled "Bosch detergent after taste" .. I have been using bicarbonate soda and 2 drops of eucalyptus oil in place of detergent or powder and use white vinegar as my rinse aid and find this has been the only way I don't get that horrid after taste.

My dishes come out really clean and glasses are streak free.

Tony Lawrence (author) from SE MA on February 08, 2012:

Good luck.

mklsvg on February 08, 2012:

Hi all, no luck yet. i'm trying to get the motivation to call the salesman yet again. they've been cooperative but seems like next step is to replace the dishwasher. what a pain! another house call.

Tony Lawrence (author) from SE MA on January 10, 2012:

I don't like wasting the water either, but I'm not going to drink soap scum, so..

Phrolica on January 10, 2012:

I have exactly the same problem with my Bosch dishwasher. I've also tried doing an extra quick wash after the dishwasher's done, but that's not really environmentally friendly so I was hoping to find another solution.

mklsvg on January 05, 2012:

Bosch soapy suds

Wow. very interesting and impressive to see how long you've had this string. We too have soapy cups when drinking filtered water. I didn't notice at all but my wife did and now i'm a little freaked. I wonder if we should have bought the Asko machine that I wanted! Well, I'll reread this string and i'd like to know how you've resolved this. I hope you have at least. We are about ready to contact the salesman.

thanks from


Tony Lawrence (author) from SE MA on January 05, 2012:

I don't think it's necessarily Bosch. I think it is mandated low water use and phosphate free detergents.

We have found that using less soap and doing an extra "Quick Wash" after the normal cycle works for us now that the buildup has worked its way out.

Kevin on January 05, 2012:

We have been fighting the same issue for the past several months. Calling Bosch and them telling us to change the detergent - tried that, still bubbles. Called them again, and they told us yet another detergent – still got bubbles. Tried bypassing my in-line filters for the house – still bubbles. Tried no Jet Dry, Full Jet Dry, Med Jet Dry – no change. Tried different settings on Bosch – no change. Our water seems normal – not hard or soft – we get some buildup but not a lot. Since the dishwasher is still under warranty Bosh told us to call someone for service, so we called an authorized service person to which they said if they come out and find nothing wrong we have to pay around $100 for the visit. What a rip. I don’t think we’ll be buying any Bosch appliances going forward, and if we can return this I’m sure we will. The previous dishwasher we had was 17 years old – noisy, but never had this issue. CRAZY!

Tony Lawrence (author) from SE MA on November 17, 2011:

I hadn't heard of "Dishwasher Magic" but we'll try anything!

Tony Lawrence (author) from SE MA on November 17, 2011:

This article http://www.sciencedaily.com/releases/2011/11/11110... made me think that dishwashers need a redesign. Maybe someday this Ultrasonic Nozzle technology will be the answer to better washing with less water?

Mrs. Bubbles on November 17, 2011:

My Bosch dishwasher is four years old and the tech in our neck of the woods basically told us the same thing, but suggested a product called Dishwasher Magic that you turn upside down in the utensil basket and let it run through a cycle. I first did two rounds of the vinegar, Dishwasher Magic and now I am doing another round of the vinegar...still suds. Also, although the water is hot, the "sanitized" sensor light no longer lights up at the end just the "clean" light. Anyone else have this problem?

Sandy on November 06, 2011:

I've been having the same bubble issue w mine! We have hard water, heavy minerals, little iron. I made a batch of detergent, 1 part borax, one part kosher salt, one part soda ash. STILL HAVE FOAM! How is this even possible?

Tony Lawrence (author) from SE MA on October 21, 2011:

Yes, we did try that. It didn't help. We use the Trader Joe's now (1/4 of the amount that would fill the container) and use an extra "quick wash" without soap after the normal wash. That seems to work well enough, although it took a long time to get the built-up soap out of the machine.

TiredinSeattle on October 21, 2011:

Did you ever try the 7th gen?
