Bosch Oven Error Code Er6 — Door Lock Mechanism Defective
What this means
Error Er6 indicates a problem with the oven's door lock mechanism, which is primarily used during the self-cleaning cycle. The lock motor may be jammed, the latch switch may be faulty, or wiring to the lock assembly may be damaged. The oven may refuse to start a self-clean cycle or may lock and not unlock.
Step-by-step fix
4 stepsTry a self-clean reset
If the door is stuck locked, try running the self-clean cycle briefly and then canceling it. This can reset the lock mechanism.
Wait for the oven to cool completely before the lock will release.
Power cycle the oven
Turn off the breaker for 5 minutes and turn it back on.
Inspect the lock assembly
Check the door lock motor and latch for physical damage or obstruction. The lock assembly is usually at the top of the oven behind the control panel area.
Test the lock motor
Use a multimeter to check the lock motor for continuity. Replace if it shows an open circuit.
When to call a professional
If the door is locked and you cannot open it, a technician can safely disengage the lock mechanism.
