Thermador Dishwasher E8000 Reports a Door Sensor Circuit Problem

What E8000 means

You shut the door, yet the dishwasher refuses to start or quits partway, and the display reads E8000. Thermador documents this number as an error in the door sensor circuit. The control confirms the door is shut before it runs anything, and that confirmation is not arriving cleanly. Because the door is a safety item, the control refuses to continue.

Usual causes of E8000

A door switch or sensor that has failed
Damaged wiring at the latch

✓ A safe check worth trying

1. Switch the dishwasher's breaker off for thirty seconds, then restore power. 2. Open the door fully and close it firmly until it latches. 3. Check that no dish or utensil keeps the door from closing. 4. Try a cycle. Never bypass or tape over the latch.

! Why you should stop here

The door sensor is part of the safety interlock, so a technician should diagnose it instead of working around it.
A latch tricked into reporting a closed door could let water spray out during a cycle.

Taking off a panel yourself does not by default void a manufacturer warranty, yet it can lead to accidental damage, and some manufacturers attach their own service terms. Read your warranty paperwork, or ask us, before you decide.

E8000E8000 questions

Will it run cycles with this sensor problem?

Not reliably. The sensor works as a safety interlock that the control checks before running, so a bad reading usually blocks the start. We would rather you ask than guess at a part.

The door seems to latch fine. Why does the code remain?

A latch can feel solid while the sensor behind it fails to report. That is why E8000 can persist even when everything looks and sounds normal.

Can I hold the door shut and press start?

No. Defeating the interlock puts water and electricity at risk. We test the switch and wiring and replace whatever has failed. Describe what you saw when you book.
