Oven shows F10 and will not start any cooking program

Safety first: Disconnect the oven from mains power. If the door is locked and the oven is hot, allow it to cool completely before attempting to open.

Step-by-step checks:

• 1. Check door closure: Ensure the door closes fully and evenly. Look for bent hinges or a damaged latch hook.
• 2. Listen for lock operation: On pyrolytic Zanussi ovens, start a cleaning cycle (with power on, by a qualified person) and listen for the lock motor. If there is no sound, the door lock mechanism may be faulty.
• 3. Access door lock assembly: Remove the top or front panel to access the door lock. Inspect for broken plastic parts or a jammed mechanism.
• 4. Test microswitches: With power off, test the continuity of the door lock microswitches while operating the lock manually. Replace the lock assembly if the switches do not change state.
• 5. Check wiring: Inspect the wiring harness from the lock to the control board for breaks or loose connectors.
• 6. Replace door lock: Fit a new Zanussi door lock assembly if the motor or switches are found to be defective. Ensure correct alignment so the door latches smoothly.

Warning: Never force the door open during or after a pyrolytic cycle; internal temperatures can be extremely high.
