Won't start and the display alternates between dl and f

Hi. This is a Door lock mechanism failure code.

A Door Lock Error occurs if the door cannot be locked. It will try to lock it six times before displaying the error code.

Possible Causes / Procedure

• Door lock mechanism is broken or removed from door.
• Door switch/lock unit failure.

1. Unplug washer or disconnect power.
2. Check door switch/lock unit. Make sue it is mounted correctly, and not loose.
3. Check the wire harness connections to the door switch/lock unit and Central Control Unit (CCU).

If the door lock unit is mounted correctly, and the wires that link the device to the main control module, and connected well, this will lead to a failed lock mechanism. replace the door lock mechanism, in this case.
