Display shows E20; pyrolytic self-clean cycle cannot start or aborts shortly after starting.

Safety first: Ensure the oven is cool and isolated from mains before internal checks. Pyrolytic cycles reach very high temperatures; never bypass safety devices.

• Check door lock: Confirm that the door closes and locks firmly when a pyrolytic cycle is selected. If not, inspect and replace the door lock assembly.
• Inspect pyrolytic sensor: Some Amica pyrolytic models use a dedicated high-temperature sensor. Test its resistance according to service data; replace if open or out of range.
• Test heating elements: Verify that both lower and upper/grill elements have correct resistance and no visible damage. Replace any failed element.
• Check safety thermostats: Reset any manual-reset thermal cut-outs on the oven casing. Replace permanently open devices.
• Re-test cycle: After repairs, run a short pyrolytic test under supervision to ensure the cycle starts and continues without E20.
