E22 – Dishwasher error code

Thermador Dishwasher error code

E22 should be documented with date, which function was active (bake, broil, burner, wash, dry), and any recent outages. For Dishwasher service, that context speeds diagnostics on the first visit.

Avoid forcing high heat or bypassing safety interlocks to “test.” If you notice unusual odor, tripped breakers, or gas smell, stop use and call for help immediately.

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.
