FAQ

Thermador service—answered clearly

Process, pricing, and what to expect during your visit.

If water remains, the door will not latch, or you see leaks, pause cycles and call. Note the code and whether drain or fill sounds abnormal—repeated runs can worsen water damage.

On some models UP relates to update or firmware state. Check the manual for whether to wait one cycle; if it persists or blocks washing, schedule service with model and serial.
