What E22 usually means
E22 usually points to a filter or drain-path restriction category.
Codes can vary by exact Bosch dishwasher model number, production year, and regional design. Use this as first-pass guidance, then confirm the model-specific manual or manufacturer support page before opening panels or replacing parts.
First checks
Remove the filter as the manual allows, rinse debris away, and check that the filter is seated correctly before restarting.
A loose or dirty filter can cause poor wash results, standing water, and repeated drain-related warnings.
- Clean the filter assembly.
- Check for debris below the filter area only if accessible.
- Reinstall the filter firmly.
- Confirm the sink drain is not slow.
When to stop
Stop if E22 remains after the filter is clean and seated, or if water remains in the tub after a drain test.
Keep the full model number, exact E22 display text, cycle name, and timing ready before contacting Bosch support or a qualified technician.
Model numbers affected
Commonly searched model families include built-in dishwashers, front-control dishwashers, top-control dishwashers, and compact dishwashers.
This is not a confirmed model-number list. Match the exact code to the full model number on the appliance tag before ordering parts, opening panels, or booking service.
