Thermador E01 error code

The heating circuit isn’t working, so water won’t reach temperature and dishes stay wet or dirty — we test the heater and control.

Because a code points to a likely area rather than an exact part, we run a full on-site diagnosis to confirm the real cause — testing the components above and the wiring and controls behind them. You get a clear, flat-rate quote before any work begins, and most E01 faults are resolved on the first visit with quality parts and a parts-and-labor warranty.
