Oven door remains locked after cycle ends; error displayed; door cannot be opened

Safety first: Switch off power and allow the oven to cool completely before attempting to open a locked door.

• Power reset: Turn off the oven at the mains for 10–15 minutes, then restore power. Some models will attempt to reset the lock on power-up.
• Manual release: Consult the user or service manual for the manual door release procedure. Many Ariston ovens have a mechanical release accessible from the top or through the front panel using a tool.
• Access lock assembly: Once the door is open, disconnect power again, remove the top/front cover, and inspect the lock mechanism for signs of overheating, deformation, or broken parts.
• Test lock motor and switches: Measure resistance of the lock motor and verify continuity of the lock position switches. Replace the lock assembly if any component is defective.
• Check PCB outputs: If the lock assembly is good, the main control board may not be driving the lock correctly. Replace the PCB if necessary.

Warning: Do not attempt to force the door open with tools; this can shatter the glass and cause injury.
