How to Read a Thermador Code
When a Thermador oven or dishwasher detects a fault, it shows a code and often pauses the cycle. The letter tells you the family, the number narrows the component. Because Thermador spans several control generations, the exact meaning of a given code varies with model and year, so treat any chart as a starting point and confirm against your model. The value of the code is that it points a technician straight at the right subsystem.
Oven Codes
Oven faults commonly cover the control board, the keypad, and the temperature sensor. An F1 or similar control or stuck-key fault sometimes clears with a few minutes of removed power; if it comes back, the keypad or board is the cause. Sensor-related codes mean the oven cannot trust its temperature reading and will not heat correctly until the sensor or its wiring is corrected. These are defined oven repairs.
Dishwasher Codes
Thermador dishwashers share the Bosch platform, so their E codes behave similarly. Drain codes point to a clogged filter, a kinked or blocked drain hose, or a failing drain pump. A leak or water-in-base code trips the base float and shuts the unit down to protect the floor. Cleaning the filter and clearing the drain path resolves many drain codes; a pump or leak fault needs parts.
Common Codes at a Glance
| Code Family | Typical Meaning | Response |
|---|---|---|
| Oven F1 / control | Control or stuck-key fault | Reset power; if it returns, service keypad/board |
| Oven sensor code | Temperature sensor open/short | Replace sensor or repair wiring |
| Dishwasher drain (E) | Filter, hose, or drain pump | Clean filter and hose; replace pump if needed |
| Dishwasher leak (E) | Base float tripped by water | Find and stop the leak; reset base |
| Heating fault | Element or flow heater | Diagnose heating circuit |
