Dishwashers can be temperamental at the best of times. But it is possible for many problems to be diagnosed and fixed without the need for a large repair bill, or worse still, a new dishwasher.
Checking online search engines for this kind of thing is my first port of call, and I usually find the answer immediately. This is because, more often than not, there are people who have had the same problem and have written about it somewhere on the internet.
I recently had a problem where my Hotpoint Aquarius FDW60 dishwasher would not fully empty, and two alarm lights would flash to indicate there was a problem. The first snag was that our instruction booklet did not tell us what the two flashing panel lights meant. Every other code was listed, except for the ones we wanted. After Googling the question, it was apparent that there was a blockage in the filter/pump.
Note: If you want to see what the alarm codes mean, a quick search online will yield the results for most of the codes. For instance, many codes can be found in this helpful guide from Spares.
Check the Filter First
So, if you think the pump on your Hotpoint Aquarius might be blocked, you may be wondering: What do I do now? The best way to find out whether or not your dishwasher has a blocked pump is to check the filter first.
Begin by opening the drop-down front door and removing the metal shroud surrounding the filter. Gently pull out the filter and you will see the hole left. Look inside for any restrictions in the wastewater trap. I advise ladling out any water that is sitting in the bottom of the machine, as you will shortly be tipping the machine on its side. This will save you from having to clean up the kitchen floor later.
The best way to find out whether or not your dishwasher has a blocked pump is to check the filter first.
Clear Out the Blocked Pump
If the filter is all clear, tip the machine on its side so that you get access to the panel on the underside. There are about six self-tapping screws to remove in order to allow the bottom plate to come free. In front of you now, you will see the pump to the right, in front of the main motor. Loosen the screw that attaches the pump to the main body, and twist the pump in a counterclockwise direction, just like removing a bayonet light bulb from its fitting. You should now be able to see inside the body of the pump.
Looking inside the pump, there is a set of fins that should rotate. If the fin does not rotate, then there is almost certainly a blockage. Gently tap the body of the pump in your hand, and the obstruction should clear and fall out. (It may take a few goes of it before the contents are freed up.)
Put It All Back Together
Now that the blockage is clear, all that's left to do now is a reverse of the procedure you have just performed.
Carefully place the pump back on its fitting and gently—very gently—push and twist the pump home in a clockwise direction. Once the pump is fixed back into its position, fasten it back up with the self-tapping screw. On the pump, there are three locating lugs. Undue force will break the lugs, so it is imperative that you use the minimum of force when twisting back into place. A new pump will cost between £35 and £50, so it could be costly if you are unfortunate enough to break all the locating lugs.
Put the plate back on the underside of the machine, and lift the machine up to an upright position. Put back the filter and shroud, and you are ready for the all-important test.
If you managed to clear it, then the machine will work as it always has done. If not, you will get the warning lights on the front panel again after a few minutes of the dishwasher being turned on—and you might have to try the entire process all over again.

Hi Posh coffee, you saved me again, blocked pump, followed instructions and I have a working dishwasher again. That's twice I have followed your advice, twice you have saved me money! Thank you I owe you a posh coffee. Tracey843. Merry Christmas!

I recently got rid of my Aquarius washing machine because it was playing up and I couldn't find out how to fix it myself. Probably if I had called in a repairer it could have been mended, but I wasn't prepared to risk the expense. Bad housekeeping, and over-cautious you might think, but I have had a problem with a dishwasher repair not so long ago, and ended up paying £120 but still having to buy a new one. It's made me a bit cagey.

Hi, I used all your advice, which was great and easy to follow however my machine still doesn't drain the water. I didn't have any warning lights and still don't have any, it works, starts a prewash cycle and starts to leak as it fills up with water. Any ideas? I think I need to replace the filter pump but thought I would check in case it was another issue, filter pump and pipe appear clear as I poured hot water through both. Model is aquarius FDW60G, thanks

Anthony Banks, which model do you have and which lights are flashing. Will try to help if I can. Thanks for reading and commenting.

Nice wee Hub.
I have a hotpoint dishwasher but not an aquarius. I find the one I have to be very tempramental. I tried unblocking it as you say but that hasn't cleared it, the warning lights still come on... next thing is to get Hotpoint out to look at it but that's £100 before they even do anything. Thanks for your advice.

I just want to say, I followed the instructions above and my dishwasher is now working. As a lady who doesn't have guy around to help with these things, I am impressed I managed this by myself without any help. Explained brilliantly, clear and concise. Really helpful page, I am most impressed. Thank you!
