Oven door will not lock for pyrolytic/self-clean cycle, or error appears when starting clean mode

Safety: Disconnect mains power. Do not force the door; you may bend hinges or damage the glass.

• Access lock assembly: On many Hotpoint pyrolytic ovens, the lock is located at the top front, accessible by removing the top cover or control panel.
• Inspect mechanism: Check for bent linkages, broken plastic parts, or obstructions preventing the lock bolt from moving.
• Test lock motor: Disconnect the lock motor and measure its resistance. An open circuit indicates a failed motor.
• Check microswitches: Identify the lock position switches and test for continuity in locked and unlocked positions. Replace if they do not change state.
• Check wiring: Inspect the harness from the lock to the main PCB for breaks, especially where it passes near hot areas.
• Replace lock assembly: If the motor or switches are faulty, replace the complete Hotpoint door lock assembly and test a clean cycle.
