Safety first: Unplug the appliance. Ensure the drum has stopped completely and water is drained before attempting manual release.

Step-by-step checks:

Manual emergency release: Many Balay units have a manual release tab near the drain pump filter behind the lower flap. Pull the tab gently to open the door.
Inspect door handle and latch: Check that the handle operates smoothly and the latch hook is not broken. Replace the door handle/latch assembly if damaged.
Check door lock: Access the door lock assembly by removing the front seal clamp. Inspect for mechanical damage or overheating. Ensure the connector is firmly seated.
Electrical test: With the lock removed and the machine unplugged, test the lock coil and switch contacts with a multimeter. Replace the lock if readings are out of specification.
Control diagnosis: If the lock and latch are good but E07 persists, the main control module may not be energizing the unlock circuit and should be tested by a qualified technician.
