Bosch Dishwasher E22: Clean the Filter Safely

Bosch dishwasher code E22 indicates a blocked or dirty filter. Cleaning the filter is the first step. Follow the instructions for your dishwasher model, since filter designs and maintenance needs can vary.

Clean the filter

Turn the dishwasher off and remove the filter only as described in the owner’s manual. Bosch’s general dishwasher care guidance is to rinse the filter under running water and use mild soap and a soft brush to remove residue. Reinstall it as directed before running the appliance.

Maintenance frequency

Clean the filter every few months or as your model manual and use conditions require. Avoid a fixed weekly schedule unless your manual recommends it. Check the manual for the correct filter-removal and cleaning procedure.

If E22 remains after the filter is clean and correctly installed, or the dishwasher shows another symptom, stop troubleshooting and arrange qualified service. Do not remove panels or test internal components.
