Washer-dryer combo door will not lock; cycle will not start and E5 is displayed.

Safety first: Always unplug the appliance before working around the door lock or control wiring.

• Check door closure: Ensure no clothing is trapped between the door gasket and door. Firmly close the door until you hear a click.
• Inspect door strike: Examine the plastic or metal door strike on the door for cracks or looseness. Tighten mounting screws or replace the strike if damaged.
• Check door alignment: Look for sagging or misaligned hinges that prevent the latch from engaging. Tighten hinge screws as needed.
• Test door lock: With power disconnected, remove the front panel or door seal clamp to access the door lock assembly. Inspect for burn marks or broken plastic. Ensure the wiring connector is fully seated.
• Replace door lock assembly: If the lock is physically damaged or E5 persists, replace the door lock assembly with a compatible NewAir part. This typically involves removing mounting screws, disconnecting the harness, and installing the new lock in the same position.
