SECTION E - 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 switch
and the sensor.
Dispenser Drawer Reed Switch
The dispenser drawer reed switch is a safety switch that
prevents the washer from operating in the wash or rinse
cycles with the dispenser drawer 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
dispenser 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.
