Quick answer
E22 means the dishwasher filter is blocked or not passing water normally. Let the water cool, isolate power and clean only the filter area described in the exact manual.
Safety first
Stop and check this first
- Do not reach into standing water or an unseen pump cavity. Stop for leaks, hot water, glass, repeated humming or electrical odour.
Safe checks you can perform
- Stop, cool and isolate the dishwasher
- Clean only the documented accessible filter
- Inspect the external drain route

- Do not attempt this professional task: Trace the complete drain system
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Trace the complete drain system
What they doService should inspect the sump, pump cover, impeller housing, check valve, hose, sink connection, pump and control.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Stop, cool and isolate the dishwasher
Cancel the programme, wait for residual water to cool and disconnect the dry electrical supply before opening the door.
Do not reach into standing water or an unseen pump cavity. Stop for leaks, hot water, glass, repeated humming or electrical odour.

What it means
Bosch's official United States dishwasher table associates E22 with a blocked dishwasher filter. This page is restricted to Bosch dishwashers: the same code on a washer, dryer or another appliance can mean something else, and the exact E-number and manual decide compatibility.
