About Thermador dishwasher error code E2030
What this one means
The heater inside the heat pump is not answering. 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:
- E2030, E6001 — 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 heater element in the pump
- Its wiring
- The board circuit that drives it
Then what
Nothing here is reachable without taking the machine out.
