How to Fix the Roomba Error 8 Trouble Code

Author:

I've had my own handyman business as a side job for the past few years and encounter a wide variety of home repair issues.

Roomba vacuums are wonderful household helpers and rarely need any maintenance, however occasionally they may begin to give off error codes for no apparent reason. If your Roomba vacuum's voice settings are activated, it will speak an audio message with an error code that let's you know what the problem is.

What Is the Roomba Error 8 Code?

In the case of my own Roomba 960, a cheerful English accent is now telling me "error 8, please open the Irobot app for more info." It's only slightly less annoying that it sounds like Mrs. Doubtfire, but still annoying nonetheless.

If your Roomba is telling you about an error 8 problem, it means that there is an issue with the vacuum motor in the removable dust bin. Yes, there is a vacuum motor in there!

Often you can fix the problem by opening up the top of the dust bin and removing hair or other debris that may be causing the vacuum motor not to spin.

Start by checking your Roomba's filter for dirt, then do a visual inspection for things like hair and leaves, which may have built up under or on top of the grate below the filter. Your Roomba error 8 code may be generated by a lack of air flow due to a dirty filter or debris around it.

Removing the screws from the top of the dust bin is step one.

How to Fix Roomba Error 8

In many cases all that you have to do to stop a Roomba error 8 code is to clean or replace the filter located in the dust bin. If your Roomba is still giving an error eight code after cleaning the filter and checking for debris in the dust bin, then perform the steps below:

  1. Start by removing the dust bin from your Roomba robot vacuum.
  2. Using a #1 Phillips screwdriver (the small one in your tool kit) remove all of the screws in the top of the dust bin.
  3. Carefully lift up the dust bin and remove the two plastic arms to disengage the lid from the bin. See the photo below which shows the plastic arms.
To remove the lid from the dust bin you must disengage the two small plastic arms, which simply slip into a hole and which can be lifted out with your fingers.

Clean the Motor

The next step is to clean any pet hair or other debris which may be causing the motor not to spin. In the case of my own Roomba, which was giving out an error 8 code, the vacuum motor was unable to spin because of a buildup of pet hair.

  1. Locate the vacuum motor (circular object in center of photo below), and using a pair of tweezers remove any pet hair or debris which may be preventing it from spinning.
  2. Next use canned air, (which you can purchase in home improvement and computer stores), and spray inside all parts of the vacuum motor and surrounding area until it's nice and clean.
  3. Using your tweezers, try and turn the small black fan on the vacuum motor. It should spin freely. If it does not, your vacuum motor may need replacing.
  4. Replace the lid by replacing the two small plastic arms and snapping the lid in place.
  5. Replace the screws and reinstall the filter in the dust bin.
  6. Place the dust bin in the Roomba and press start.
The cause of this Roomba error 8 code was a buildup of pet hair.

What to Do If This Does Not Fix Roomba Error 8

If the above steps fail to remove the error eight code from your Roomba, then you may need to replace the entire bin and vacuum motor assembly. If your Roomba is under warranty, this may be done through the factory. If your Roomba is out of warranty, you may be able to purchase a refurbished bin on eBay or Amazon. There are both after market and OEM dust bins available for Roomba vacuums.

In the case of my own Roomba model 960, the steps above worked at first to remove the error 8 code. Later however, more pet hair eventually clogged up and burned out the small vacuum motor, and I was forced to purchase a new dust bin assembly, which includes the motor.
