UP – Dishwasher error code

Thermador Dishwasher error code

UP on a Thermador dishwasher typically indicates an update or firmware-related state on models that support connected diagnostics—your manual will say whether the appliance should finish the cycle on its own or needs service.

If water remains in the tub, the door will not latch, or the code stays for multiple cycles, pause use and note any leak or pump noise.

Contact Thermador Support at 844-683-0648 with model and serial so we can align symptoms with the right repair path.

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.
