Washer-dryer combo shows E40 and will not start; door symbol may flash.

Safety first: Do not slam the door; this can damage the lock.

• Clear obstructions: Check the door gasket for clothing, coins, or debris preventing full closure.
• Close firmly: Push the door until you hear a distinct click from the Midea door lock.
• Inspect hinge and strike: If the door appears sagged or misaligned, tighten hinge screws and adjust as needed.
• Check gasket condition: A deformed gasket can prevent proper closure; replace if torn or badly warped.
• Persistent E40: If the door is clearly closed but E40 remains, the door lock assembly may be weak or faulty and should be replaced.
