Washer-dryer displays 3L and may not lock the door or start high-speed spin.

Safety first: Disconnect power before accessing the door lock. Do not bypass safety interlocks.

Steps to resolve:

• Check door alignment: Ensure the door closes evenly and the hinge is not sagging. Adjust hinge screws if the door is misaligned.
• Inspect gasket: Make sure the door gasket is seated properly and not folded or obstructing the latch.
• Access door lock: Pull back the front of the door gasket after removing the retaining clamp to expose the door lock assembly.
• Check connectors: Verify that all connectors on the lock are fully seated. Look for broken plastic tabs or loose terminals.
• Replace lock if needed: If the lock appears damaged or 3L persists, replace the door lock assembly. Reinstall gasket and clamp carefully to prevent leaks.

If the new lock does not resolve 3L, the main control board may not be reading the lock feedback correctly and should be checked by a technician.
