About Thermador dishwasher error code E22
What this one means
The machine cannot pull water through the filter fast enough. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
The other ways your machine may say it
The same condition is published under more than one label, because it has been carried across generations of this appliance:
- E22, E-22 — the same condition, on machines of different ages
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- The mesh filter under the lower arm
- The coarse filter above it
- Debris sitting in the sump
What to try yourself
- Lift out the filter assembly and wash it under the faucet with a soft brush
Then what
This one is genuinely a five-minute job, and it is the most common code on any dishwasher of this platform.
This code is published for dishwashers. The full list of codes has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
