Bosch Oven E115 Error Code: Door Lock Fault

Quick Answer

Bosch E115 is a door lock fault that appears during self-clean initiation or cancellation. Bosch wall ovens use a motorized door lock with a position sensor. E115 triggers when the motor runs but the sensor does not confirm the locked or unlocked position within 45 seconds.

Bosch E115 is a door lock fault that appears during self-clean initiation or cancellation. Bosch wall ovens use a motorized door lock with a position sensor. E115 triggers when the motor runs but the sensor does not confirm the locked or unlocked position within 45 seconds. Bosch door locks are more complex than Whirlpool's bimetal system - they use a gear-driven motor with a microswitch for position feedback. The lock assembly is behind the oven's front panel. Common causes: worn motor gears (the small plastic gears inside the lock assembly strip after years of self-clean use) or a failed position microswitch.
