Thermador HU error code
Humidity control fault
The humidity system that protects corks isn’t regulating — we check the humidity sensor and related parts.
Likely causes
- Faulty humidity sensor
- Blocked humidity reservoir
- Humidity control fault
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 HU faults are resolved on the first visit with quality parts and a parts-and-labor warranty.
