Safety: Switch off and unplug the appliance. Wait several minutes to allow the lock to cool.

Emergency opening: Many Zanussi models have an emergency door release near the pump filter. Pull it gently to open the door.
Inspect lock: Access the door lock and check for signs of overheating or mechanical jamming. Replace the lock if damaged.
Check wiring: Ensure the harness to the lock is secure and not pinched.

If the lock is new and wiring is sound, the control board may be failing to release the lock and should be tested by a professional.
