General (Dryer)
The dryer uses heated air to dry loads of laundry.
When the motor is started, the exhaust fan pulls fresh
air in through louvers at the rear of the dryer and over
the heat source (burner flame for gas and heating
element for electric). The heated air moves through the
heater duct and into the cylinder, where it circulates
through the wet load. The air then passes through the
lint filter, air duct and exhaust fan, where it is vented
to the outdoors.
General (Washer)
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, removes 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 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
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 or drain
valve 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 (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 (Washer)
The basic operational system of this washer consists of
the electronic control, the inverter control, pressure
switch, water valves, electric pump (or drain valve)
and A.C. motor.
The electronic control performs all control and timing
functions like the timer in a topload washer. The
electronic control sends simple speed and output
commands to the inverter control via serial
communication. The electronic control powers the
door lock, pump and the inverter control.
The inverter control powers the A.C. motor and
performs all motor control functions. The inverter
control also powers the water and dispenser valves and
passes the pressure switch status to the electronic
control. The inverter control is powered through the
door switch, door lock switch and electronic control.
The inverter control also alerts the electronic control to
any errors in the motor.
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 the
drum 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.

Troubleshooting
1. TROUBLESHOOTING COIN DROP
When coin is placed into coin slot, the coin should roll
down drop and be heard dropping into coin vault. If
coin does not fall into coin vault or if coin drop sensor
does not register that coin has been entered, follow
troubleshooting instructions on following page. Refer
to Figure 1 for path that coin follows when working
properly.
IMPORTANT: Never use oil to correct coin drop
problems. Oil residue will prevent coins from
rolling properly.
IMPORTANT: Do not bend or damage mechanical
parts within coin drop.

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 belt. Refer to
