This guide walks through the Thermador appliances we service most, the faults behind the usual complaints, and how our technicians read each one before quoting a repair.
Signature Systems
Thermador is known for the Star burner and ExtraLow simmer on its ranges, the Freedom induction cooktops, and the Sapphire dishwashers, and each has its own service profile. The dishwashers report numeric E-codes that make water and drainage faults easier to localize, while the cooking products lean more on burner and control diagnosis. Repair timing depends on diagnosis and parts availability.
Codes We See Most
The dishwasher E-codes below are the ones that come up most often. They share the same logic as other BSH-built machines, so the E15 base-pan trip and the E24 drain fault behave the way they do on Bosch, with model-specific genuine OEM parts fitted on repair.
| Code | What It Means | What We Check |
|---|---|---|
E15 | Water in the base pan, safety float tripped | Leak source and float switch |
E24 | Drainage blocked or slow | Filter, drain hose, and pump |
E22 | Filter or drain restriction | Filter basket and sump |
