Possible Causes

How to Fix / Troubleshooting
Safety first: Disconnect the appliance from mains. The door lock mechanism may move unexpectedly if powered.
Steps:
- Check door closure: Ensure the oven door closes fully and the latch engages. Look for bent hinges or obstructions.
- Listen for lock motor: On pyrolytic (self-cleaning) models, start a cleaning cycle and listen (with power on) for the lock motor. If silent, the motor or control may be faulty.
- Access lock assembly: Remove the top panel or front trim (per Brandt service instructions) to reach the door lock. Inspect for broken plastic parts or disconnected rods.
- Test microswitches: With a multimeter, check continuity of the lock switches when the lock is engaged and disengaged. Replace the lock assembly if switches are defective.
- Check wiring: Ensure the harness from the lock to the control board is intact and firmly connected.
