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.
