SECTION IV:
Part Replacement
Once the root cause of a failure has been determined, it may be
time to replace parts. When major part replacement of the
various washer systems is required, use this section’s various
procedures for assistance.
Replacing the PC Board, Display Panel and Button Pad
The PC (timer) Board, Display Panel and Button Pad are all part of the
Control Module Interface. The PC Board is where the user inputs
settings and sets up a program; it’s also where they get information
from the timers and sensors in the washer. Use the procedures below
to access the control module and replace parts when there is a control
failure.
**Completely drain and disconnect electrical power to the unit before
proceeding with any of these instructions.
Accessing the Control Module
1. Open the washer’s door.
2. Remove the mounting screws on the door’s backside that secures the
grey, plastic Control Panel and the screws on the side of the door that
secure the front panel (this must be removed to pull off the controls).
3. Lift the door and remove the mounting screw that holds the plastic knob
to the door latch.
4. Pull the Control Panel from the door to access the Control Module.
5. Remove wiring pin connectors as necessary for the needed repairs.
