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 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 (refer to 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 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 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 inverter
control immediately stops and then restarts the
spin.

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.

1. MOTOR CIRCUIT
Resistance Values:
Tachometer Circuit:
Terminals 4–5
Approx. 115 ohms
Windings:
Terminals 1–2, 2–3, 1-3
Approx. 4.5 ohms
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. Refer to
Paragraph 31.

WARNING
3. ERROR CODE LISTING
Error Conditions
If any of the following errors occur, the control enters Error Mode. For all fatal errors, the control will terminate
the current cycle, turn off all outputs, and flash two LEDs one second on/one second off to indicate the error.
Motor Failure
Error.
If the control receives the motor failure signal from the motor control, the control will
enter Error Mode. The control will turn off all outputs and flash the DOOR and FINAL
SPIN LEDs one second on/one second off to indicate a motor failure error. This is a fatal
error. The machine must be unpowered to clear this error.
Fill
Error.
If the control receives no full input from the pressure switch indicating the cylinder is full
within 30 minutes of starting the fill, the control will enter Error Mode. The control will
turn off all outputs and flash the WASH and DOOR LEDs one second on/one second off
to indicate a fill error. This is a fatal error. The machine must be unpowered to clear this
error.
Door Open
Error.
If the control senses the door open during Run Mode, the control will enter Error Mode.
The control will turn off all outputs and flash the WASH and RINSE LEDs one second
on/one second off to indicate a door open error. This is a fatal error. The machine must
be unpowered to clear this error.
Door Lock/Unlock
Error.
If the door doesn’t lock in 15 seconds in Door Locking Mode or the door doesn’t unlock
in 3 minutes in Door Unlocking Mode, the control will enter Door Lock Error Mode. The
control will turn off all outputs and flash the DOOR LED one second on/one second off
to indicate a door lock/unlock error.
To clear this error in Door Locked Mode the door must either open or lock. If the door
locks, the cycle will start normally. If the door opens, the control will revert back to Start
Mode.
To clear this error in Door Unlocking Mode the door must unlock or open. If the door
unlocks or opens, the control will enter End of Cycle Mode.
SPI
Communications
Error.
This error occurs when there is a problem with communications between the front-end
control and the motor control. The control will turn off all outputs and flash the FINAL
SPIN and RINSE LEDs one second on/one second off to indicate an SPI
communications error. This is a fatal error. The machine must be powered down at this
point.
Open/Shorted
Temperature
Sensor Error
(Models equipped
with heater)
Any time the control senses a temperature less than 32°F (0°C) or greater than 212°F
(100°C) while heating, the control will turn off the heater output and not attempt to heat.
The control will continue and finish the cycle normally. At the end of the cycle the
control will flash the HEATING LED one-second on/one second off to indicate an open/
shorted temperature sensor error. This error will be cleared when the door is opened at
the end of the cycle.
