WARNING
Safety Information
Throughout this manual and on machine decals, you will find precautionary statements (“CAUTION,”
“WARNING,” and “DANGER”) followed by specific instructions. These precautions are intended for the personal
safety of the operator, user, servicer and those maintaining the machine.
DANGER
Danger indicates an imminently hazardous situation that, if not avoided, will cause severe personal injury or death.
WARNING
Warning indicates a hazardous situation that, if not avoided, could cause severe personal injury or death.
CAUTION
Caution indicates a hazardous situation that, if not avoided, may cause minor or moderate personal injury or property
damage.
Additional precautionary statements (“IMPORTANT” and “NOTE”) are followed by specific instructions.
IMPORTANT
The word “IMPORTANT” is used to inform the reader of specific procedures where minor machine damage will
occur if the procedure is not followed.
NOTE
The word “NOTE” is used to communicate installation, operation, maintenance or servicing information that is
important but not hazard related.
In the interest of safety, some general precautions relating to the operation of this machine follow.
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.

WARNING
NOTE: The WARNINGS and IMPORTANT INSTRUCTIONS appearing in this manual are not meant to
cover all possible conditions and situations that may occur. Common sense, caution and care must be
exercised when installing, maintaining or operating the washer.
Always contact your dealer, distributor, service agent or the manufacturer about any problems or conditions you do
not understand.
Locating an Authorized Servicer
Alliance Laundry Systems is not responsible for personal injury or property damage resulting from improper
service. Review all service information before beginning repairs.
Warranty service must be performed by an authorized technician, using authorized factory parts. If service is
required after the warranty expires, Alliance Laundry Systems also recommends contacting an authorized
technician and using authorized factory parts.
The cycle begins with a wash fill. The water
temperature is determined by the temperature selected
on the control. While water fills the washtub, a column
of air is trapped in a pressure bulb and hose. The air
pressure continues to increase as the washtub fills with
water until it is great enough to trip the pressure sensor
at the selected water level (load size). The pressure
sensor trip then causes the wash fill to stop and wash
agitation to begin. However, the lid must be closed for
any washer operation to occur.
The washer uses a reversing type motor, a special drive
belt and an idler assembly. The idler assembly applies
tension to the outside of the drive belt.
During agitation, the motor runs in the
counterclockwise direction. The spring tension on the
idler pulley applies the tension required to reduce the
slack on the drive belt and maintain maximum belt to
motor pulley contact. This eliminates belt slippage and
ensures an efficient wash action, even with extra large
loads.
The belt drives the transmission drive pulley in the
counterclockwise direction. The pulley drives the helix
which is splined to the input shaft of the transmission.
This causes the input shaft to turn inside of a roller
clutch which is pressed into the transmission cover.
This roller clutch acts as a bearing in the
counterclockwise direction allowing the transmission
gears to operate. The transmission’s rack and pinion
gear design produces a 210 degree agitation stroke at
the output shaft of the transmission which drives the
agitator. The brake assembly remains locked during the
agitation mode since no pressure is applied to it by the
transmission drive pulley.
As water is removed by the pump and the momentum
of the washtub increases, the idler spring tension
gradually overcomes the belt tension removing the belt
slack. This eventually increases the belt to pulley
contact until maximum spin speed is achieved.
The drive pulley turns clockwise riding up the ramps of
the helix, exerting pressure on the brake and forcing it
to release from brake pads. The helix drives the input
shaft of the transmission, and when the input shaft turns
in the clockwise direction the roller clutch locks onto
the shaft causing the entire transmission assembly to
turn. None of the gears in the transmission are
operating at this time. The hub of the washtub is splined
to the transmission tube and rotates with the
transmission assembly. The centrifugal acceleration
created by the spinning washtub causes water to be
extracted from the clothes.
Water is introduced during the first spin to “SPRAY”
the garments and remove suds from them. The initial
spin is followed by a rinse step to rinse away any
detergent residue.
During the rinse step in the Normal Eco cycle there is a
spray rinse. Water is sprayed into the washtub while it
is spinning. In all other cycles, the washer fills and then
agitates like the wash portion of the cycle.
Following the rinse step a final spin extracts the rinse
water from the clothes preparing them for the dryer.
Refer to Cycle Sequence Charts section for a detailed
breakdown of each cycle.
After the wash agitation is completed and a short pause
occurs, the control advances into the first spin. During
spin, the motor reverses turning in the clockwise
direction to spin the water out of the washtub. The
combination of water, washtub and load weight cause
the drive belt tension on the idler side of the belt to
overtake the idler spring pressure allowing the belt to
become slack on the opposite side. This reduces the
belt to pulley contact and allows slipping between the
belt and pulley.

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.

Refer to Figure 2.
a. Place rubber feet on all four leveling legs.
b. Place washer in position on a clean, dry, and
reasonably firm floor.
c. Loosen locknuts and adjust two front leveling
legs. Once adjusted, tilt washer forward on
front legs and lower back down into position to
set the rear self-leveling legs.
d. Washer must not rock. After washer is at
desired height, tighten locknuts securely
against bottom of washer base. If these locknuts
are not tight, washer will not remain stationary
during operation.
NOTE: Improper installation, installation on
carpet or flexing of a weak floor will cause
excessive vibration.
IMPORTANT: Do not slide washer across floor
once leveling legs have been extended, as legs and
base could become damaged.
