TIMER SEQUENCE
1- When the Start Cycle TC (20519) button is
depressed. The small contactor relay is energized and
closes contacts CR1 (20067) and CR2 (20067). This
has two purposes. The first one is to energize both the
timer motor and the indicator light LC (20042). The
second purpose is for CR2 to bypass the Start Switch
TC.
2- The timer motor is energized and starts to turn and
closes the first contact M1 (20518) which will bypass
the small relay contactor and keep the timer motor
running during the entire cycle.
3- As the timer cam continues to turn, the second
switch M2 (20518) is closed and energizes the wash
pump motor.
4- After 150 seconds approximately, switch M2 opens
and switch M3 (20518)closes to energize the solenoid
valve (for rinsing), the drain pump and the detergent
pump. This function lasts about 20 seconds and the
circuit reverts to the beginning.
