If your Bosch dishwasher displays the E22 error code, it usually means the dishwasher has detected a problem with the filter system, most commonly a blocked or dirty filter.
The good news is that E22 is often something you can troubleshoot yourself. Cleaning the dishwasher filter and checking for food debris or other blockages may resolve the error. However, if the code keeps returning, there may be a deeper drainage or pump-related problem.

What Does E22 Mean on a Bosch Dishwasher?
The E22 error code on a Bosch dishwasher generally indicates a dirty or blocked filter.
The filter prevents food particles and debris from entering the dishwasher’s drain system. Over time, grease, food residue, and mineral buildup can restrict water flow. When the dishwasher cannot circulate or drain water properly, it may display E22.
In simple terms:
E22 = Check and clean the dishwasher filter and drainage area.
The exact meaning can vary by Bosch model, so use your owner’s manual as the final reference for your specific appliance.
Why Is My Bosch Dishwasher Showing E22?
Several issues can cause an E22 code, including:
- A dirty dishwasher filter
- Food debris trapped around the filter.
- Grease or mineral buildup
- A partially blocked drain system
- Debris near the drain pump
- A drainage problem that prevents proper water flow
In many cases, the filter is the first thing you should check because it is accessible and relatively easy to clean.
How to Fix E22 on a Bosch Dishwasher
Before troubleshooting, turn off the dishwasher and disconnect it from power if possible. Be careful when reaching into the bottom of the dishwasher because broken glass or sharp debris can be present.
1. Remove the Bottom Rack
Pull the lower dish rack out of the dishwasher. This gives you access to the filter assembly at the bottom of the tub.
2. Remove the Filter
Bosch dishwashers commonly use a removable filter assembly near the bottom of the dishwasher.
Twist or lift the filter according to your model’s design. If you are unsure how it comes out, check your Bosch owner’s manual rather than forcing it.
3. Clean the Filter Thoroughly
Rinse the filter under running water and remove food particles, grease, and other buildup. A soft brush can help loosen stubborn residue.
Avoid using anything that could damage the filter mesh.
4. Check the Filter Housing
Cleaning the filter itself may not be enough. Inspect the area underneath and around the filter for food particles, broken glass, labels, or other debris.
Remove anything that is visibly blocking the area.
5. Reinstall the Filter Correctly
Place the filter back into position and make sure it is securely locked. A loose or incorrectly installed filter can cause additional dishwasher problems.
6. Run the Dishwasher Again
Restore power and run a short wash or rinse cycle I f the E22 code does not return, the problem was likely related to the dirty or blocked filter.
If E22 returns shortly afterward, further troubleshooting may be necessary.
What If Cleaning the Filter Doesn’t Fix E22?
If you have cleaned the filter and the E22 error continues to appear, don’t repeatedly run the dishwasher hoping the code will disappear. The problem could involve another part of the drainage or circulation system.
Possible causes include:
- A blockage deeper in the drain system
- Debris around the drain pump
- A restricted drain hose
- A pump or circulation problem
- A sensor or control-related issue
At this point, consult the manual for your exact Bosch model or consider having a qualified appliance technician inspect the dishwasher.
Can You Use a Bosch Dishwasher With E22?
It is generally better not to continue using the dishwasher while the E22 error is present. The error indicates that the dishwasher has detected a problem affecting its operation. Continuing to run repeated cycles without addressing the cause could leave water in the appliance or make an existing blockage worse.
Start by cleaning and checking the filter. If the error remains, investigate further or arrange professional service.
How Do You Prevent E22 From Coming Back?
Regular maintenance can reduce the chance of filter-related problems.
Try these simple habits:
- Clean the dishwasher filter regularly.
- Scrape large food particles from dishes before loading them.
- Check the bottom of the dishwasher for debris.
- Keep the filter properly installed.
- Avoid allowing grease and food residue to accumulate.
- Follow the cleaning and maintenance recommendations for your Bosch model.
You do not need to make your dishes completely spotless before loading them, but removing large food scraps can help reduce the amount of debris entering the dishwasher’s filtration system.
Frequently Asked Questions
