Section 2 Introduction
General
This frontload washer provides some of the same
principles of operation as the typical topload washer. It
senses water level, it dispenses the desired laundry
detergent, tumbles the clothes for good cleaning
action, pumps the water out of the washer and spins
the clothing for preparing for the dryer.
The difference in operation is primarily the rotational
washing cycle that tumbles the clothes in a timer
controlled clockwise, pause and then a counter-
clockwise direction. This reversing cycled tumbling
action provides a much more efficient washing process
which requires less laundry detergent and less water.
The cycle begins by locking the loading door with a
wash fill command from the timer. The water
temperature is determined by the temperature selector.
If the boosted heat water temperature is selected, an
internal heater is activated. This internal heater will
raise the water temperature approximately one degree
per minute up to a final temperature of 140 degrees.

Section 2 Introduction
While water fills the inner basket, 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. Then the pressure switch causes the wash fill
to stop and starts the reversing rotational washing
cycle.
The reversing rotational cycle tumbles the clothing in
a clockwise direction for a period of 20 seconds,
pauses for 9 seconds and then tumbles the clothing in a
counterclockwise direction for 10 seconds. This action
continues until the completion of the wash cycle
selected on the timer.
Upon completion of the wash cycle, the machine goes
into a rinse cycle. The rinse cycle consists of a spin
mode that removes the majority of the detergent water
from the clothing and also activates the electric water
pump which removes the wash water. Fresh
temperature selected water is brought into the inner
basket via the mixing valve, the pressure switch shuts
off the water and then a rinse cycle starts. The rinse
cycle consists of a tumble reversing action similar to
the washing cycle for a pre-determined amount of
time, a spin mode, and includes water being pumped
out and fresh water being brought into the washer.
Several of these rinse cycles will take place, based
upon the operator timer wash type selection and the
optional activation of the “Extra Rinse” switch
selector on the control panel.
After all the rinse cycles have been completed, the
washer goes into a 1059 rpm final spin cycle for 90
seconds to extract as much water as possible from the
clothing, preparing them for the dryer. When this fast
spin cycle is completed, the washer goes into a fluff
tumble mode similar to agitate, only without water.
Operation stops and the loading door interlock is
deactivated allowing operator entry into the washer.
Technical
The basic operational controls of this washer consist of
the motor control logic board, timer, pressure switch,
temperature switch, D.C. motor and electric pump.
The principle of operation remains the same as other
washing machines. The door locks and starts the timer.
The timer starts the machine process by first having
the electronic control activate the dual water inlet
mixing valve which starts to fill the washer via the
dispenser mixing valve. The water temperature is
determined by the operator-selected temperature
switch position, which selects the hot, cold or both
mixing valves. The second step is adding the detergent
and other washing ingredients. This process continues
until the air pressure, via the pressure bulb and hose,
activates the pressure switch, which overrides the
timer fill command.
The timer continues its rotational cycle, which then
sends the command to the motor control board to start
the timer rotator. The tumble rotating action is a
specific wash cycle rotation, pause and then reverse
rotation. This process continues for an operator’s
selected period of time.
The next command mode the timer signals to the
motor control board is to start the rinse cycle. This
cycle signals the electric pump to turn on and direct
the wash water out of the washer. The motor control
board then commands the motor to go into a faster
spin cycle in an attempt to remove a reasonable
amount of water out of the clothing. The spin cycle
stops and then adds fresh rinse water into the washer
via the inlet mixing valve and dispenser hose. After
the pressure switch shuts off the water inlet mixing
valve, the motor control board commands the motor to
start the normal wash rotational, pause, reverse
direction process for a timer-controlled amount of
time. This rinse cycle is completed twice unless the
extra rinse switch has been selected by the operator.
Another rinse cycle takes place each time the extra
rinse switch is selected.
The next portion of the wash cycle is the spin cycle. In
this cycle the control board turns the electric pump on
to remove the rinse water from the tub. The washer
will spin at a distribution speed of 90 rpm until the
pressure switch is satisfied as empty. The washer then
goes to a 500 rpm spin for 30 seconds and returns to
the 90 rpm distribution speed for another 30 seconds.
This allows the motor control board to “sense” the outof-balance condition of the load. This sequence is
repeated any time the washer attempts to go to a spin
speed. At this time the washer then goes into a final
spin mode of 650 rpm for approximately 5 minutes
and ramps up to 1059* rpm for the remaining 90
seconds.
*(For Regular and Rinse and Spin cycles only).

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.

Troubleshooting
FLOW CHARTS AND SCHEMATICS
FOUND ON THE FOLLOWING PAGES
ARE FOR MODELS COVERED IN THIS MANUAL.
1. 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.
2. NO MOTOR ROTATION, OR DRIVE FAILURE CODE “E:DF” ON ELECTRONIC DISPLAY UNITS
NOTE: Verify that motor is receiving proper voltage. Disconnect electrical power to washer.
TEST PROCEDURE
a. At the rear of the washer, remove the lower access panel.
b. Reach in through the access panel opening and disconnect motor wire harness from motor.
c. Using an Ohmmeter, measure resistance at the terminals on the motor. Refer to Tab le 1 .
Motor Resistance Values
TACH INPUT Terminals 6-7 Approximately 15 Ohms
BRUSHES Terminals 4-5 Less than 70 Ohms
WINDING Terminals 1-3 Approximately 1.1 Ohms
WINDING Terminals 1-2 Approximately 2.0-2.4 Ohms
WINDING Terminals 2-3 Approximately 3.4 Ohms
NOTE: Resistance values may vary depending on type of Ohmmeter used.

WARNING
d. Replace motor if there is an open circuit on tach input (terminals 6-7) or winding circuits (terminals 1, 2 and
3), or if there is continuity between any terminal and the motor housing.
e. An open circuit between terminals 4 and 5 indicates a stuck or warn brush. Refer to appropriate service
procedure below.
SERVICE PROCEDURE: STUCK BRUSHES
a. Remove motor from washer.
b. Using a flashlight, view brushes through holes in motor end shield. Refer to Figure 1.
c. Inspect both brushes to determine if either brush braided wire is binding the brush movement. The braided
wire might be snagged on the seam in the corner of the metal brush holder. Refer to Figure 1.
NOTE: The copper braided wire should be located in the center of the brush assembly. If the braided wire
has fallen to the bottom of the brush, it will cause binding.
d. After determining which brush assembly is binding, carefully use the tip of a small screwdriver to unsnag
and reposition the braided wire. Refer to Figure 2. Make sure spring is making unobstructed contact with the
end of the brush. Rotate armature by hand to assure that brushes are seated.
e. Recheck resistance between motor terminal 4 and 5 to verify the brush position has been corrected.
f. Reinstall motor in washer.

Section 3 Troubleshooting
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.
