OPERATION
Control
The control is mounted to the back of the console.
The control:
1. Provides power to the dispenser solenoids,
wax motor, door lock solenoid, drain pump and
speed control board.
2. Sends signals to the speed control board to
tell it what program to run.
4. Checks the status of the reed switch, door
switches and the sensor.
Dispenser Drawer Reed Switch
The dispenser drawer reed switch is a safety switch
that prevents the washer from operating when the wash
or rinse cycles when the dispenser drawer is open. The
switch is located behind the control panel next to the
dispenser drawer. The electronic control board sends a
signal through the reed switch circuit. When the signal
is interrupted by the contacts of the reed switch being
open, the board prevents the washer from operating.
The reed switch contacts are controlled by the magnetic
field of the magnet located in the front panel of the dis-
penser drawer.
When the drawer is closed, the magnet causes the
contacts of the reed switch to close completing a circuit
in the control board.
Door Switch Assembly
The door switch assembly, located behind the front
panel, is a safety feature that prevents the washer from
operating when the door is open and locks the door in
the spin cycle.
