Washer-dryer reports door open even when closed, cycle will not start

Safety first: Disconnect power before disassembling the door area.

• Check door alignment: Gently lift the door to see if there is play in the hinges. Tighten hinge screws if the door sags.
• Clean contact area: Wipe the door hook and lock opening to remove detergent residue that may prevent full engagement.
• Inspect lock connector: Remove the door seal clamp and access the lock. Ensure the multi-pin connector is fully seated.
• Replace lock if needed: If the machine still thinks the door is open, replace the door lock assembly, which contains the status switch.
• Further diagnosis: Persistent issues after lock replacement suggest a wiring or control board fault, best handled by a technician.
