Pyrolytic self-cleaning does not start; oven beeps and returns to normal mode without error code.

Safety first: Ensure the oven is empty and cool before starting pyrolytic cleaning.

Steps:

• Remove all racks, telescopic runners, and accessories as required by the manual.
• Allow the oven to cool to room temperature if it was recently used.
• Close the door firmly and check that nothing obstructs the latch.
• Verify that child lock or safety lock is deactivated.
• Re-select the pyrolytic program and confirm according to the user manual sequence.

If the cycle still will not start, the door lock or temperature monitoring system may be faulty and should be checked as described in the door lock and sensor sections.
