What's Happening
The fine mesh filter is clogged, preventing proper water drainage from the sump. Food particles, calcium buildup, and grease accumulate over time. Regular monthly cleaning prevents this error.
How to Fix It
Remove the entire filter assembly, separate the inner and outer filters, and clean thoroughly under running water. For stubborn buildup, soak in white vinegar for 30 minutes. Reinstall and run a rinse cycle to test.
Frequently Asked Questions
What does E22 mean on a Bosch dishwasher?
E22 means the fine filter is clogged with food residue. This is a maintenance issue, not a broken part — cleaning the filter fixes it.
How often should I clean my Bosch dishwasher filter?
Bosch recommends cleaning the filter monthly. If you run the dishwasher daily or wash heavily soiled dishes, every two weeks is better.
Can vinegar help with a Bosch dishwasher E22 error?
Yes. Soaking the filter in white vinegar for 30 minutes dissolves calcium and grease buildup that regular rinsing can't remove.
