Thermador Dishwasher E06 Error: Door Sensor Lock Fault
thermador dishwasher e06 error indicates door sensor lock fault. Review the diagnostic steps below before calling a technician for help. What Does Thermador Dishwasher Error Code E06 Mean? The E06 error code on a Thermador Sapphire, Star-Sapphire, Emerald, or Topaz dishwasher means the control board cannot confirm that the door is properly latched. Every Thermador […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. E06 prevents the cycle from starting entirely — this is a safety lockout. Do not attempt to bypass the door sensor. If the door cannot be confirmed latched, water entering the tub could escape and cause floor damage.
Can I reset the code?
Yes. If the latch was not fully engaged, closing the door properly and pressing Start effectively resets E06. If the sensor has failed electrically, a breaker reset will not help — the sensor must be replaced.
When to stop immediately?
Stop if you notice: Door still shows E06 after firm closure and latch inspection, Door gasket is pulled away from the tub, suggesting recent door stress.
Symptoms You May Notice
Pressing Start has no effect and E06 appears on the display
The dishwasher powers on and accepts program selection, but pressing Start produces E06 and no cycle begins. The door appears closed to the user but the sensor disagrees.
Door feels loose or does not click firmly when closed
The door does not produce a solid latch click on closure, or it can be opened again with minimal force, indicating the latch strike or hook has worn.
E06 appears intermittently — sometimes the cycle starts, sometimes it does not
An intermittent E06 suggests a failing door sensor rather than a completely broken latch — the sensor is borderline and sometimes passes the check, sometimes fails it.
Possible Causes
Worn or misaligned door latch mechanism
The plastic or metal latch hook on the door or the strike on the tub frame has worn to the point where the door does not engage the latch sensor firmly enough.
DIY PossibleFailed door position microswitch or Hall-effect sensor
The electronic sensor that detects latch engagement has failed electrically and reports an open-door state even when the door is fully closed.
Requires ProfessionalLoose wiring connector to the door latch assembly
The wiring from the door latch sensor to the control board has come loose at a connector inside the door, typically disturbed by a door-slam event or prior service.
Requires ProfessionalSafe Checks You Can Do
-
1
Close the door firmly and try again
Open the dishwasher door fully, then push it closed with a deliberate firm press — not a slam — until you hear and feel the latch engage. On Thermador Sapphire and Star-Sapphire dishwashers the latch has a distinctive click. Try pressing Start immediately after the click.
Some Thermador dishwashers have a latch that requires the door to be pushed to the closed position and then given a slight additional push toward the tub rather than simply swinging shut. Check your model's use and care guide for the correct latching technique.

Inspect the door gasket and latch strike for obstructions
Look at the latch strike on the tub frame and the hook on the door for visible debris, broken plastic, or deformation. Also check that the door gasket is fully seated in its channel — a gasket that has slipped out of the channel can prevent the door from closing flush.
A small piece of broken dishware or food debris lodged in the latch strike is a surprisingly common cause of intermittent E06 on Thermador Star-Sapphire and Topaz models.
When to Call a Professional
Contact a qualified technician if:
- Door latch sensor shows open circuit even when latch is mechanically engaged
- Latch hook is cracked, bent, or missing a retention tab
- E06 returns immediately after the door is closed on every attempt
