Thermador spans nearly the entire kitchen, from its signature star-burner ranges to Freedom induction cooktops, column refrigeration, and quiet Sapphire dishwashers. Because Thermador is built on the BSH platform, its dishwashers and some electronics share diagnostics with Bosch and Gaggenau, which means the fault codes are familiar and the parts are well supported. We service the cooking, refrigeration, and cleaning sides of a Thermador kitchen with one team.
Models We Service
- Ranges: Pro Harmony and Pro Grand gas and dual-fuel with the Star burner and ExtraLow settings.
- Cooktops: Freedom induction, Masterpiece induction, and sealed-burner gas cooktops.
- Wall ovens: Masterpiece and Professional single and double ovens.
- Refrigeration: Freedom and built-in refrigerator and freezer columns, and under-counter units.
- Dishwashers: Sapphire, Star-Sapphire, and Emerald series.
Error and Fault Codes
Thermador dishwashers use the BSH E-code system, the same family as Bosch, so the codes below are the ones we see most. Cooking and refrigeration faults are more often diagnosed by symptom, though newer electronic ovens may show a fault indicator. We always confirm a code against the actual condition of the appliance before ordering parts.
| Code / Symptom | Meaning | Fix |
|---|---|---|
| E15 | Water in the base tray, leak float tripped | Find and repair the feeding leak, dry the sensor |
| E24 | Drainage blocked or restricted | Clear the filter, hose, and drain pump |
| E22 | Filter or circulation fault | Clean the filter, check the circulation pump |
| Star burner clicks, no flame | Wet cap or spark module | Dry, re-seat, replace the module |
| Induction zone fault | Coil or power board | Isolate and replace the component |
Common Problems We Fix
On the cooking side, the extra-large Star burner cap is the usual suspect when a burner sparks but will not light, and Freedom induction faults tend to isolate to a single zone's coil or the power board. Wall ovens most often need a temperature sensor. Sapphire dishwashers bring the familiar E15 base-tray leak and E24 drainage complaints, which we trace to the source rather than simply resetting. Column refrigeration shares the same fan, defrost, and sensor faults common to all premium built-ins.
