CYCLE FUNCTIONS - TIMER OPERATED MODELS
FILL CYCLE:
The fill cycle is initiated as the user
rotates the Timer dial to the "fill" posi-
tion for any of the three cycles available
(Permanent Press, Delicates and
Regular Fabrics) and pulls out the
Timer knob. Pulling out the Timer knob
allows the L1 side of the power supply
(refer to schematic) to go through the
Line Switch and on to the time.
Timer Cams are closed during fill which
allows L1 to go through the Timer and
on to the Temp Switch. Depending
upon what water temperature is
selected, L1 is routed through the Temp
Switch and on to une or both of the
Water Valve solenoids. This is a 120
VAC water valve.
The Neutral side of the power supply
(refer to schematic) is routed through
the Pressure Switch and 1 amp fuse and
on to the Water Valve. With L 1 and
Neutral at the Water Valve, one or both
solenoids will be energized (depending
upon temperature selected). The tub
16001145
begins to fill with water, regardless of
lid position.
AGITATION CYCLE (Start and Run):
The lid must be closed in order for the
machine to agitate. During fill, the
water in the tub will rise until a selected
level is reached (small, medium, or
large) which causes the contacts inside
the pressure switch to move from the
"fill" to the "run" position. When this
happens, the water valve is de-
energized and neutral is routed to the
motor run windings through timer cams
to the motor start windings. L 1 is
routed to the run windings through the
line switch, the normally open contacts
on the lid switch and through the
normally closed contacts in the check
switch. L1 is routed to the start
windings through the line switch, the
normally closed contacts on the check
switch and through the timer. At about
75% of full speed, the drive motor's
centrifugal switch "opens" and drops
the start winding out of the circuit. The
drive motor is running and agitation
begins.
