General
This frontload washer provides some of the same
principles of operation as the typical topload 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 15
seconds, pauses for nine seconds and then tumbles the
clothing in a counterclockwise direction for 15
seconds. This agitation continues until the wash 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 (refer to Table 1 or Table 2).
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 control, temperature switch, inverter control,
pressure switch, water valves, electric pump, A.C.
motor and cycle select switch.
The control performs all timing functions like the timer
in a topload washer.
The inverter control uses a speed sensor on the motor
to measure the drum RPM. Before entering any spin
step, the inverter control measures the RPM of motor to
sense out-of-balance. The inverter control will try to
redistribute the clothes if an out-of-balance condition
exists; the inverter 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 inverter control will limit speed to
90 RPM and will not spin.
NOTE: An out-of-balance switch is used to detect
any out-of-balance condition during spins. If this
switch opens during a spin step, the inverter control
immediately stops and then restarts the spin.

Troubleshooting
1. Motor Circuit
2. 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 belt.
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer before servicing.
• Never start the washer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer is properly grounded.
• Motor not grounded! Disconnect electric power before servicing motor.

3. No Spin Due to Out-of-Balance Switch Wiring Problem Starting Serial
Nos. Beginning 0307
A “no spin” condition could be the result of an open circuit in the wire harness or out-of-balance switch. First, check
that the harness is still connected to the out-of-balance switch. The out-of-balance switch is a normally closed
switch. (continued)
Figure 1
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer before servicing.
• Never start the washer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer is properly grounded.
• Motor not grounded! Disconnect electric power before servicing motor.

Troubleshooting
If broken wires are found at the out-of-balance switch
wire support, cut off portion of wires as shown in
Figure 1 and add new UL approved terminals.
a. To test the electrical circuit, disconnect
electrical power to the washer.
b. Remove the “H1” connector from the inverter
control assembly.
c. Use an Ohm meter to check the black/white to
violet/white wires. Circuit should read closed.
An open reading indicates a bad switch or
wire harness problem.
d. Flex the harness at the plastic wire clamp and
test continuity. If the base wire harness has an
open circuit it MUST be replaced or the
broken wires must be repaired with UL
approved terminals.
e. After replacing or repairing the wire harness,
wrap electrical tape around wires in two
locations as indicated below and in Figure 1.
Then secure the harness wires to the original
factory locations using clamp and wire tie.
Refer to Figure 1.
(1) The plastic wire clamp should be angled
toward the switch at 45 degrees.
(2) The clamp should wrap around the first
section of tape on the harness, which should
be placed approximately 4.5 inches (11.43
cm) from end of terminals.
(3) The harness should be secured to the
inverter control shield with a wire tie.
(4) The tie should wrap around the third section
of tape on the harness, which should be
placed approximately 14 inches (35.56 cm)
from end of terminals. Refer to Figure 1.

Troubleshooting
6. Troubleshooting Shock Absorbers
A squeaking noise, oil seen on the base of the washer,
or an out-of-balance condition may mean one or more
shock absorbers need to be replaced.
To determine if there is an inoperative shock:
1. Remove front access panel.
2. Check height of rod or rod spacing above shock.
If all four shocks are uniform and have about two
inches of rod showing when basket is empty,
shocks don’t need replacing. Refer to Figure 3. If
one or more shocks is showing less than two
inches of rod, then an internal spring has broken
and all four shocks should be replaced.
3. Check base of washer below shock absorbers for
grease or oil. Shocks are not oil filled. Any oil is
from grease used internally to lubricate damper of
shock. A small amount of grease/oil on base is
normal and doesn’t indicate failure. A large
amount of grease/oil indicates a shock that might
fail soon. Do not replace shock until the internal
spring has broken as described in Step 2.
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer before servicing.
• Never start the washer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer is properly grounded.
• Motor not grounded! Disconnect electric power before servicing motor.
