What this code can mean
Bosch identifies trapped food debris in the dishwasher filter as the primary condition behind E22.
Safe first checks
- 1Turn off the dishwasher before handling the filter.
- 2Follow the model manual to remove and wash the user-serviceable filter with mild soap and a soft brush.
- 3Reinstall the filter securely before running a test cycle.
Possible causes
- Food particles or other debris are blocking the dishwasher filter.
- The filter has not been cleaned or reinstalled correctly.
Stop conditions
- Stop if broken glass, sharp debris, leaking water, or wet electrical areas are present.
- Request service if the filter cannot be removed safely or E22 returns.
Use Bosch support or an authorized servicer when correct filter cleaning does not clear E22.
