Washer will not start; E40 or door symbol error displayed

Safety first: Ensure hands are clear of the door area when closing.

Steps to check and address E40:

• Close door firmly: Push the door until you hear a clear click. Do not slam excessively.
• Check hinge alignment: Inspect the door hinge screws; tighten if loose. Ensure the door lines up with the cabinet opening.
• Inspect latch and lock: Check the metal latch on the door and the lock opening on the cabinet for damage. Replace the door lock assembly if it does not engage reliably.

When to call a technician: If mechanical parts are fine but E40 persists, the lock circuit on the PCB may be defective.
