Operating Characteristics - GE WPSE7003A0 Technical Service Manual

Basic Washer Operation
The typical washer cycle progresses as
follows:
• Fill: timed, 40 minutes maximum
• Agitation: 12 minutes
• Pump Out: 3 minutes
• Spin: 3 minutes
• Rinse Fill: timed, 40 minutes maximum
• Rinse: 3 minutes
• Pump Out: 3 minutes
• Final Spin: 6 minutes
Basic specifications for the motor, pump,
relays, and water valves are:
• Motor: 1/2-hp, 10 A, 70 A in-rush,
120 VAC
• Pump: 3.2 A, 120 VAC
• Relays: 12 VDC
• Water Valves: 0.1 A each, 120 VAC
• Lid Switch pauses all washer operations,
except water fill, when the lid is raised. The
lid switch cuts power to the DC relay coil for
the motor.
• Pressure Switch has two switches in one
housing. The first switch will open when
there is 6 in. of water in the basket. The
second switch will open when the water in
the tub has reached the maximum level.
The second pressure switch is in series
with the DC relay coils of both water valve
relays. The system for the pressure switch
reads OPEN with water in the tub. Mid level
fills are timed based on lowest level.
Washer Fill Mode
Fill mode activates the water valves accord-
ing to the temperature selected. The cycle
advances to the next mode as soon as the
pressure switch opens. A fail-safe control
system prevents serious flooding due to a
failure in the pressure switch system. The fill
is timed, and the water valves de-energize
after 40 minutes if the pressure switch has
not been tripped. The cycle then stops. If this

fault is triggered, the display will show a 1,
the PerfecTemp LED will flash, and the
washer will be in the PAUSE mode.
If the user changes the water temperature
during fill, the change occurs immediately.
During the wash fill, one of four lights will be
on to indicate selection, and will progress as
the cycle advances.
Wash, Rinse, and 2nd Rinse
Agitate Modes
Wash, rinse, and 2nd rinse operate the
motor in agitate mode at the selected wash
speed. Relays switch speed, motor direction
for spin or agitate, and main power to the
motor. When speed is changed and the
motor is running, relays go through the turn-
off sequence, and then turn ON at the newly
selected speed.
The WASH light remains ON during pump
and spin when the washer is in the rinse
cycle. The RINSE and 2ND RINSE lights are
on during fill, rinse, and pump, while the
washer is in the extra rinse cycle.
Drain Pump-Out Mode
The control board has circuitry that detects,
through the pump control relay, a measure-
ment of electrical current to the pump motor.
That current describes the motor's output
torque which can determine if the pump is
pumping water or pumping air.
After pumpdown, the control enters a clothes
care sequence. Basically, the pump stops
then starts for a few seconds. The unit then
begins a slow speed spin and changes to a
fast spin after a few seconds. See spin
speed flowchart on page 24.
