Oven shows F14 and may not start; often related to door lock on pyrolytic models.

Safety first: Disconnect power. Be cautious of sharp edges when working around the door lock area.

Step-by-step checks:

• 1. Check door closure: Ensure the door closes fully and is not obstructed by racks or warped seals.
• 2. Access lock assembly: On many Hotpoint-Ariston ovens, the lock is located at the top front. Remove the top cover or front panel to access it.
• 3. Inspect mechanism: Look for bent levers, broken plastic parts, or signs of overheating. Manually move the lock arm to see if it moves freely.
• 4. Test microswitches: Using a multimeter, check continuity of the lock position switches while manually operating the lock. Replace the lock assembly if switches do not change state reliably.
• 5. Check motor: Measure resistance of the lock motor coil. An open circuit indicates a failed motor.
• 6. Replace lock assembly: Install a genuine Hotpoint-Ariston door lock assembly, transferring wiring one connector at a time.
