Oven shows F13 during or after a pyrolytic self-cleaning cycle

Safety first: Allow the oven to cool completely and disconnect from mains before inspection.

Step-by-step checks:

• 1. Check installation clearances: Ensure the oven has the ventilation gaps specified by Zanussi. Overheating during pyrolytic cleaning can trigger F13.
• 2. Inspect cooling fan: Confirm the cooling fan runs strongly during normal operation. Replace if weak or noisy.
• 3. Locate pyrolytic sensor: Some models have a dedicated high-temperature sensor or thermostat for pyrolytic mode, usually on top of the cavity. Inspect wiring and connectors.
• 4. Test sensor/thermostat: With power off, measure resistance of the pyrolytic sensor or check continuity of the high-limit thermostat. Replace if open-circuit or out of specification.
• 5. Reset thermostat (if applicable): Some high-limit devices are resettable; press the reset button if present.

Warning: Do not run a pyrolytic cycle again until the cause of F13 is identified and corrected; extreme temperatures are involved.
