Smart summary for E22
This quick AI-style overview sums up how serious this error is, how hard it usually is to fix yourself and roughly how long it takes.
What E22 means
Error E22 usually means dirty water cannot leave the dishwasher fast enough because the filter system or sump area is blocked.
Common causes
- Filter mesh clogged with food debris or grease
- Foreign objects stuck in the sump area
- Occasional build‑up of limescale and residues
Quick checks you can do yourself
- Turn the machine off and remove the lower basket.
- Twist and lift out the filter assembly, then rinse under warm running water.
- Check the sump opening below the filter for food scraps, glass or labels.
- Wipe around the area and re‑fit the filter securely before running a short rinse cycle.
Always unplug the appliance and switch off power at the mains before removing panels or working near wiring or water connections.
When to call a professional
If the filter and sump are clean but the dishwasher still leaves standing water or shows repeated E22 errors, the drain pump or control system may need professional diagnosis.
Recommended next steps
Rinsing the filter every few washes and scraping plates before loading greatly reduces the chance of E22 returning.
