FILL
3. The water level transducer will sense the water
level in the basket and send a signal to the micro-
computer assembly. The microcomputer supplies
the water level transducer with 5VDC on pin 3 of
connector P1. The water level transducer outputs
a signal based on the amount of water in the bas-
ket between pins 1 and 3 which progressively illu-
minate the indicator LEDs on the LOAD SIZE op-
tions indicator.
4. If the water level reaches an overfill condition
mechanical contacts on the water level transducer
will remove the CPU 120V from pin 7 of connector
P1. This is the power to energize the fill valves.

1. The washer will fill automatically with warm water for approximately 90 seconds through the de-
tergent dispenser when the START pad is touched. The STATUS display will indicate Fill/Wash.
2. The washer will then switch to regular fill through the Hot and Cold water inlet valves. The water
will enter the washer through the water inlet vacuum brake at the rear of the tub. The Hot and/or Cold
valves will energize depending on the water temperature selected.

AGITATE
1. Once the basket is filled the COMAG applies 120V from P9 to energize the start capacitor and the
start winding of the drive motor.
2. Once the motor is up to speed the Centrifugal Switch will open disconnecting the start capacitor
and start winding.
3. 120V is also applied directly to the
drive motor through Pin P8 (AG HI),
P13 (LMED) or P14 (LLOW) to control
the drive motor agitate speed.
(Fig. 5)
4 When the agitate cycle is complete
voltage is removed from the drive
motor.
