Bosch Dishwasher E22 code: Filter blocked
The filter at the bottom of the dishwasher is clogged, which limits how well water circulates and drains.
Most common causes
- Food debris packed in the filter
- Filter not cleaned regularly
- Filter not seated correctly
What you can safely check yourself
- Remove the filter and wash it under running water with mild soap and a soft brush.
- Reinstall it so it locks in place.
- Scrape large food scraps off dishes before loading.
Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.
