Note: Before disconnecting hose from water level switch, be sure water level in machine is below
bottom of wash basket. After reconnecting hose, put machine in spin for at least 1 minute before
checking operation of switch.
To remove water level switch:
1. Place the control panel in the service position (see
procedure).
2. Remove the screw securing the switch.
3. Disconnect wiring and hose from switch, and
remove.
Electronic Control Board
The electronic control board consist of 2 circuit boards
connected by 2 ribbons. The boards are attached to
the back of the control panel and control all washer
functions. The boards are replaced with the control
panel as an assembly.
A voltage reading between 4.5 and 5.5 VDC should be
measured at connector J2 between pin 3
(V sense) and pin 2 (sensor ground). A voltage
reading greater than 5.5 VDC indicates a faulty
electronic control board. A voltage reading lower than
4.5 indicates one of the following: Faulty electronic
control board, faulty wire harness between J2 and
CN9, or faulty inverter.
If a faulty board is suspect, check for continuity across
the fuse and visually inspect the surge protector
mounted on the board. If no continuity is read across
the fuse, or if the surge protector appears burnt or
damaged, replace the board.
If a faulty electronic control board is diagnosed, check
the water valve snubber (see Water Valve), pump
snubber (see Pump), and inverter snubber (see
Inverter) for a shorted condition. If a shorted snubber
is detected, replace the snubber before installing the new control.
