F9 error on oven display, door lock symbol may flash and self-clean will not start (on pyrolytic models)

Safety first: Disconnect power. Ensure the oven is cool before working on the door lock.

• Check door alignment: Make sure the door closes fully and evenly. Adjust hinges if the door is sagging.
• Inspect lock mechanism: Access the door lock assembly from the top or front (depending on model). Look for mechanical obstruction or bent parts.
• Test lock motor and switches: Use a multimeter to test the door lock motor and associated microswitches for continuity.
• Lubricate lightly: Apply a small amount of high-temperature-safe lubricant to moving parts if they are stiff (avoid over-lubrication).
• Replace lock assembly: If the motor does not run or switches do not change state, replace the complete Hansa door lock assembly.

Warning: Never force the door open during a self-clean cycle; allow the oven to cool and unlock automatically or have a technician release it.
