Step 1

Accessing the Display PCB

To remove the Display PCB begin with removing the two mounting screws on both sides of the Display Assembly.

1. Start by pressing in on the screw cover located on the sides of the control panel. Press in on the “Flat Side” of the cover:

2.  When you press the flat side of the screw cover, the cover will stay open so that you can easily remove the screw. And remember there is a screw on both sides of the panel.

3.  Use a #2 phillips screwdriver to remove the two screws that are holding the panel in place. (One screw on each side of the panel).

Step 2

uninstall the assembly.

With the screws removed, start at one end of the Display Assembly and pull out gently to uninstall the assembly.

Step 3

Checking Voltages.

The connector for the Wash unit is on the bottom, and the connector for the Dryer is on the top (the names are imprinted on the plastic).

There should be 15 Vdc on the OR and RD lines all the time. If you have no voltage at the display, replace the Main PCB. If you do have 15Vdc at the Display PCB, but still no message, replace it.
