Washer-dryer combo displays E18 and may not start; often related to door open detection.

Safety first: Ensure the door is closed before starting any cycle. Unplug the unit before adjusting hinges or lock components.

• Verify closure: Push the door firmly until you hear it latch. Check that the door sits evenly in the frame.
• Inspect hinge and strike: Look for sagging hinges or a bent/broken strike. Tighten hinge screws and replace damaged parts.
• Check gasket: Ensure the door gasket is not folded or obstructing closure.
• Door lock inspection: Access the door lock assembly and verify the wiring connector is secure. Replace the lock if the internal switch does not change state when the door is closed (technician test).
• When to replace parts: Replace the door lock assembly or door strike if they are worn or broken.
