Bosch dishwashers E22 error

The dishwasher filter is blocked.

E22

What this code can mean

Bosch identifies trapped food debris in the dishwasher filter as the primary condition behind E22.

Safe first checks

  1. 1
    Turn off the dishwasher before handling the filter.
  2. 2
    Follow the model manual to remove and wash the user-serviceable filter with mild soap and a soft brush.
  3. 3
    Reinstall 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.
