Thermador has been a fixture of American luxury kitchens for decades, and its star-burner cooktops, Professional ranges and Freedom refrigeration columns show up throughout Evergreen and the surrounding resort communities. As part of the Bosch appliance group, Thermador shares a robust electronic control platform, which is good news for diagnosis: many faults surface as a clear code that points a trained technician straight at the failed circuit. That said, the cooking side still demands hands-on skill, because a star burner that will not light or an oven that bakes off temperature has to be confirmed with a meter, not just read from a display.
We service the whole Thermador lineup and treat the codes as a starting point rather than the whole answer. A single F-code can have more than one cause, so we test before we replace. We diagnose to the root, give a written estimate, and repair with genuine OEM parts under our warranty.
Models We Service
- Professional ranges: PRD and PRG dual-fuel and gas ranges with star burners.
- Wall ovens: Masterpiece and Professional single and double ovens.
- Cooktops: star-burner gas, Masterpiece induction and electric cooktops.
- Dishwashers: Sapphire and Star-Sapphire panel-ready dishwashers.
- Refrigeration: Freedom refrigerator and freezer columns and built-ins.
Error and Fault Codes
Thermador cooking products display F-codes for control and sensor faults, and Thermador dishwashers, which run on the Bosch Group platform, display E-codes. Here are the ones we see most often. We always confirm the underlying part with a meter before replacing it.
| Code | Meaning | What the Fix Involves |
|---|---|---|
| F1 / F7 | Control or stuck-key fault | Test the keypad and control board |
| F2 | Oven over-temperature | Check the sensor and relay, replace as needed |
| F3 / F34 | Oven temperature sensor fault | Test and replace the sensor |
| E15 (dishwasher) | Water in the base pan | Find the leak, reset the Aqua-Stop |
| E22 / E24 (dishwasher) | Blocked filter or drainage fault | Clear the drain, test the pump |
Common Problems We Fix
- Star burner that clicks but will not light
- Oven that bakes off temperature or throws an F-code
- Dishwasher that will not drain, showing E22 or E24
- Water in the dishwasher base triggering E15 and the Aqua-Stop
- Induction cooktop elements that cut out or under-power
- Freedom column temperature alarms and sensor faults
- Control panels that freeze or fail to respond
- Convection fan and element faults in wall ovens
A Code Is a Clue, Not a Diagnosis
The same Thermador code can point to a sensor, a relay, or wiring between them. We test the circuit rather than swapping parts on the code alone, which keeps the repair with model-specific diagnosis.
Thermador Showing a Code?
Book a diagnosis and we will read it and confirm the real cause. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.
