Thermador E1 error code
Water-circuit or flow fault
Water isn’t flowing as expected — often an airlock, pump or flow-sensor issue in the water circuit.
Likely causes
- Airlock in the water circuit
- Failed water pump
- Faulty flow sensor
How we diagnose & fix it
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 E1 faults are resolved on the first visit with quality parts and a parts-and-labor warranty.
