Bosch E107

Bosch error code E107 indicates: The door does not open because it is locked. The display shows "Oven not unlocked"..

The primary root cause for Bosch code E107 is: A door lock produced up to FD9103 had geometry that caused the hook to rub against the door insert, blocking movement. This prevented correct actuation of the microswitches, leading the electronics to detect an incorrect switching position..

To resolve error code E107: Check if there is blocking of the lock and support of the lock; Motor lock: connection and cable controller; Engine changer lock; Check wiring according to diagram, correct; Correct position of micro-switches on the support frame; Change micro-switch; Change control module

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code E107 persists, the physical component causing A door lock produced up to FD9103 had geometry that caused the hook to rub against the door insert, blocking movement. This prevented correct actuation of the microswitches, leading the electronics to detect an incorrect switching position. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
