Section 2 Introduction

General
This front load washer provides some of the same
principles of operation as the typical top load washers.
It senses water level, it dispenses the desired laundry
detergent, agitates the clothes for good cleaning
action, pumps the water out of the washer and spins
the clothing in preparation for the dryer.
The difference in operation is primarily the rotational
washing agitation created for the horizontal basket and
drum. This agitation tumbles the clothes in a
clockwise, pause, and counter-clockwise direction.
This reversing tumbling action provides an efficient
washing process and requires less water.
The cycle begins by pressing the start button, which
locks the loading door after the vend is satisfied. The
type of cycle and water temperature are determined by
the temperature selector switch and the cycle select
switch.
The inner basket starts agitating during the wash water
fill. A column of air is trapped in a pressure bulb and
hose. The air pressure continues to increase as the
inner basket fills with water until it is great enough to
activate the pressure switch which then causes the
wash fill to stop.
The regular and perm press agitate cycle tumble the
clothing in a clockwise direction for a period of 10
seconds, pauses for nine seconds and then tumbles the
clothing in a counterclockwise direction for 20
seconds. This agitation continues until the wash soak
cycle. The machine stops agitating and turns on the
pump which removes the wash water.
Upon completion of the wash cycle, the machine goes
into two rinse cycles. Fresh cold water is brought into
the inner basket via the mixing valve until the pressure
switch shuts off the water while agitating. The rinse
cycle consists of agitation for a predetermined amount
of time, then a spin mode with the pump running while
the machine goes into a series of 4 short 500 RPM
spins.
After all the rinse cycles have been completed, the
washer goes into a final high spin cycle to extract as
much water as possible from the clothing to prepare
them for the dryer. The spin speeds and duration of
this final high spin cycle are determined by the type of
wash cycle selected (see table).
NOTE: Washer may not reach 1000 RPM because
of an out-of balance condition. Control may limit
speed to 850, 650 or 500 RPM depending on severity
of out-of-balance condition.
Technical
The basic operational system of this washer consists of
the timer, temperature switch, motor control board,
pressure switch, water valves, electric pump, D.C.
motor, transformer and cycle select switch.
The timer controls all timing functions like the timer
in a top load washer.
The motor control uses a speed sensor on the motor to
measure the drum RPM. Before entering any spin step,
the motor control measures the current draw of motor
to sense out-of-balance. The motor control will try to
redistribute the clothes if an out-of-balance condition
exists; the motor control will limit the spin speed to
several speeds depending on the severity of the out-of-
balance condition. If the out-of-balance condition is
severe enough, the motor control will limit speed to 90
RPM and will not spin.
NOTE: An additional out-of-balance switch is used
to detect any out-of-balance condition during spins.
If this switch opens during a spin step, the motor
control immediately stops the spin step and restarts
the spin step.

the clothing in preparation for the dryer.
The difference in operation is primarily the rotational
washing agitation created for the horizontal basket and
drum. This agitation tumbles the clothes in a
clockwise, pause, and counter-clockwise direction.
This reversing tumbling action provides an efficient
washing process and requires less laundry detergent
and less water.
The cycle begins by locking the loading door after the
vend is satisfied. The type of cycle and water
temperature are determined by the appropriate pads on
the Electronic control.
The inner basket starts agitating during the wash water
fill. A column of air is trapped in a pressure bulb and
hose. The air pressure continues to increase as the
inner basket fills with water until it is great enough to
activate the pressure switch which then causes the
wash fill to stop.
The agitate cycle tumbles the clothing in a clockwise

agitation continues until the wash soak cycle. The
machine stops agitating and turns on the pump which
removes the wash water.
Upon completion of the wash cycle, the machine goes
into a rinse cycle. Fresh cold water is brought into the
inner basket via the mixing valve until the pressure
switch shuts off the water while agitating. The rinse
cycle consists of agitation for a predetermined amount
of time then a spin mode with the pump running where
the machine goes into a series of 4 short 500 RPM
spins. Two of these rinse cycles will normally take
place with a third extra rinse cycle being optional.
After all the rinse cycles have been completed, the
washer goes into a final high spin cycle to extract as
much water as possible from the clothing to prepare
them for the dryer. The spin speeds and duration of
this final high spin cycle are determined by the type of
wash cycle selected (see table).
NOTE: Washer may not reach 1000 RPM because
of an out-of-balance condition. Control may limit
speed to 850, 650 or 500 RPM depending on severity
of out-of-balance condition.
Technical
The basic operational system of this washer consists of
the electronic front-end control, the motor control,
pressure switch, water valves, electric pump, D.C.
motor and transformer.
The front end control performs all control and timing
functions like the timer in a top load washer. The front
end control sends simple speed and output commands
to the motor control via serial communication. The
front end control powers the door lock, pump and the
motor control.
The motor control powers the D.C. motor and
performs all motor control functions. The motor
control also powers the water and dispenser valves and
passes the pressure switch status to the front end
control. The motor control is powered through the
door switch, door lock switch and front end control.
An auto transformer provides 240 VAC for the motor
which the motor control converts to D.C. The motor
control also alerts the front end control to any errors in
the motor.
The motor control uses a speed sensor on the motor to
measure the drum RPM. Before entering any spin step
the motor control measures the RPM of the drum to
sense out-of-balance. The motor control will try to
redistribute the clothes if an out-of-balance condition
exists the motor control will limit the spin speed to
several speeds depending on the severity of the out-of-
balance condition. If the out-of-balance condition is
severe enough the motor control will limit speed to 90
RPM and will not spin.
NOTE: An additional out-of-balance switch is used
to detect any out-of-balance condition during spins.
If this switch opens during a spin step the motor
control immediately stops the spin step and restarts
the spin step.

2. NO SPIN CONDITION – MODELS THROUGH SERIAL NO. 9811005967
A “no spin” condition could be the result of an open circuit in the wire harness or out-of-balance switch.
a. Check that the harness is still connected to the out-of-balance switch. The wiring diagram may show the out-
of-balance switch as a normally open switch which is incorrect. The switch is a normally closed switch.
b. To test the electrical circuit, disconnect electrical power to the washer.
c. Remove the “H3” connector from the motor control board.
d. Use an Ohm meter and check the black/white to violet/white wires. Circuit should read closed, an open
reading indicates a bad switch or wire harness problem.
e. Flex the harness at the plastic retainer and test the switch and if okay, the base wire harness has an open
circuit and MUST be replaced.
f. After replacing the wire harness, tape the harness wires to the left front shock 1 ½ inches from top of shock.
Refer to Figure 10.
IMPORTANT: Leave a minimum of 8 inches of slack between tape on shock and the plastic wire retainer on
the out-of-balance switch mounting bracket. Refer to Figure 10.
3. TROUBLESHOOTING KNOCKING NOISE
If a frontload washer produces a noise similar to a knock on a door, it might be due to a flat spot on the belt.
The knocking sound is made when the flat spot hits the pulley. The knocking may occur during a pulse spin
and fade after reaching a higher RPM.
To correct this condition, replace the washer belt. Refer to Paragraph 51.
