Thermador LEAK error code
Internal leak detected
The machine has detected an internal leak and stopped — we locate the failed seal or hose and repair it.
Likely causes
- Failed hose or seal
- Cracked water tank or fitting
- Loose internal connection
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 LEAK faults are resolved on the first visit with quality parts and a parts-and-labor warranty.
