F50 error, oven may not start pyrolytic cleaning or may abort the cycle.

Safety first: Disconnect power and ensure the oven is cool before working on the lock mechanism.

• Check door lock operation: Start a pyrolytic cycle and listen for the lock engaging. If it does not lock, inspect the lock assembly and wiring.
• Verify sensors: Ensure both main and overheat sensors are functioning and correctly mounted; pyrolytic mode will not start if sensors are faulty.
• Inspect lock wiring: Look for heat-damaged wires near the lock and hinge area. Repair or replace as needed.
• Replace lock assembly: If the lock motor or microswitches are defective, install a new AEG-compatible pyrolytic lock assembly.

Warning: Never attempt to run pyrolytic cleaning with a known lock or sensor fault; this can be hazardous.
