TEST #8: Lid Lock Assembly

Perform the following checks if the washer does not lock (or
unlock).
1. Perform the Lid Switch Test under Manual Test Modes on
page 2-4. The following steps assume that this step was
unsuccessful.
2. Check lid lock mechanism for obstruction or binding.
Repair as necessary.
3. Unplug washer or disconnect power.
4. Access the UI/Control Board.
5. Visually check that the CN5 and CN7 connectors are
inserted all the way into the control board.
¾ If visual check passes, go to step 6.
¾ If either connector is not inserted properly, reconnect
the loose connector and repeat step 1.
6. Remove connector CN5 from control board. With an
ohmmeter, measure the resistance across the CN5, pins 1
and 2 (see Figure 2). Resistance should be 76-94 W.
¾ If values are open or out of range, replace the lock
assembly.
¾ If values are correct, go to step 7.
