SAFETY
YOUR SAFETY AND THE SAFETY OF OTHERS IS IMPORTANT
Safety messages have been provided in this manual where performing certain procedures may
cause exposure to hazards that can kill or hurt you.
This is the safety alert symbol. All safety messages will be preceded by the safety
alert symbol and the word “DANGER” or “WARNING”.
These words mean:
YOU WILL BE KILLED OR SERIOUSLY INJURED
IF YOU DON’T FOLLOW INSTRUCTIONS.
YOU CAN BE KILLED OR SERIOUSLY INJURED
IF YOU DON’T FOLLOW INSTRUCTIONS.
All safety messages will identify the hazard, tell you how to reduce the chance of injury, and tell
you what can happen if the instructions are not followed.

1. Carefully follow the installation instructions supplied with the washer for information related to
yourproduct.
KEY POINTS TO REMEMBER:
2. Removethe shippingstrapasfollows:
a. Carefully read, then remove the yellow label securing the power supply cord to the back of
the washer. (Fig. 1-1)
b. With the washer upright, pull the yellow shipping strap completely out of the back of the
washer. Be sure both cotter pins come out of the washer. Note that the power supply cord
plug will still be attached to the yellow shipping strap.
(Fig. 1-2)
c. Firmly pull on the end of the yellow shipping strap that is attached to the bottom of the back
of the washer.
(Fig. 1-3) This will release the self-leveling leg mechanism.
Section One - Part A
INSTALLATION CONSIDERATIONS
NOTE:To prevent the two (2) shipping pins from falling on the floor, two (2) plastic
holders are attached to the base.
(Fig. 1-4) When the cotter pins are removed,
the shipping pins fall into these holders. These pins may be left in the
holder cups.
(Fig. 1-4, INSET) They will not interfere with the operation of the
washer.

3. Screw the lock nut down to within 1/2 inch of the base of the leg.
(Fig. 1-5)
4. Tilt the washer forward off the floor and set back down to adjust the rear self-leveling legs.
5. Check the washer for level, both side-to-side and front-to-back. Adjust the front legs as
necessary. Tighten the locking nuts to the base of the washer with a wrench. If the nuts
are not tightened, the washer may vibrate excessively.
6. Cut the shipping strap at the words “CUT HERE” and slide it off the power supply plug.
(Fig. 1-6)
7. The hook-end of the drain hose can be installed into a stand pipe (Fig. 1-7, A&B) or laundry
tub,
(Fig. 1-7, C) and secured with the shipping strap as shown.

NOTE: Laundry Drain Requirements:
Laundry Tub or Utility Sink -
1. Laundry tub or utility sink should have a minimum capacity of 20 gallons.
2. Top of tub or sink must be a minimum of 34” and not more than 72” from the
bottom of the washer.
Floor Drain -
1. Floor drain systems require a Siphon Break (Part No. 285320.) Siphon Break
must be above the high water level in the washer tub (a minimum of 28”
from the bottom of the washer.)
2. Additional drain hose will be required for a Floor Drain installation.
Standpipe Drain -
1. A minimum 2” diameter drain pipe with a minimum carry-away capacity of
17 gallons per minute is required.
2. Top of standpipe must be a minimum of 39” and not more than 72” from the
bottom of the washer.
COMMON INSTALLATION PROBLEMS
1. Water does not pump out.
Causes: a. Drain hose too high (over six feet).
b. Blockage or crimp in the drain hose.
c. Drain pipe not vented.
2. Water on the floor.
Causes: a. A leaking hose on the water inlet valve or faucet.
b. A leaking drain hose connection.
c. The drain hose is coming out of the stand pipe when draining.
d. Restricted drain pipe -- running beyond capacity.
3. The machine vibrates or “walks”.
Causes: a. Improperly installed front feet.
b. The washer is not level.
c. The shipping strap is not removed or a retaining pin is still attached to a
shipping pin on the base of the washer.
d. Floor not solid.
e. Rear leveling legs not set.
4. The machine doesn’t fill.
Causes: a. The water faucets are not turned on.
b. There is a blockage in the hose or the fill valves.
c. Drain hose siphoning -- too low or siphon break not installed.

Section One - Part B
THEORY OF OPERATION
All washers perform essentially the same four functions. They fill with water, agitate, drain the water
and spin the water out of the clothing.

1. Before the washer can fill, the customer makes selections that:
• Control the length of the wash cycle by turning the timer control knob
• Control the temperature of the wash and rinse water by setting the water temperature switch.
The water temperature switch is identified by the dotted box in Fig. 2-2. The wash temp switch
chartindicatesthreepossible switches, dependingonthemodel washer beingused. Theswitch
letters in the chart, H W and C are the possible water temperature selections, Hot , Warm and
Cold. The first letter is the wash temperature, the second letter is the rinse temperature.
• Control the amount of water required for the amount of clothing by setting the water level or
pressureswitch.
2. Once the selections are made, a series of switches are closed in the timer and water temperature
switch. If, for example, the customer selects the beginning of the REGULAR cycle, increment 4,
and a WARM wash and COLD rinse, the following switches would be closed.
Fig. 2-3
Fig. 2-2

The water level switch is set to move from the
EMPTYpositiontothe FULL position depend-
ing on how much tension is set on the switch
diaphragm.
3. When the customer pulls the timer knob out,
voltage is supplied to the hot and/or cold wa-
terinletsolenoids.Inthe example above, both
solenoids are energized to allow water to fill
the tub.
4. As the water level rises in the tub, it causes
an increase in air pressure in the air dome
assembly mounted to the side of the tub. A
hosebetweentheairdomeandthewaterlevel
switchtransfersthisairpressureagainstthe
diaphragm in the water level switch, causing
electrical contacts to move from V to P,
(EMPTYposition),toVto T,(FULL position).
The washer stops filling and the water level
switch is providing voltage to the timer motor
and the drive motor to begin agitation.

1. Once there is power to the timer motor, the timer will start to advance. The drive motor will also
begin to turn counterclockwise in the agitation direction. The direction of current through the dirve
motor start winding will determine the direction the drive motor runs. In the agitation mode, con-
tacts 7 are closed, causing current to flow in the start winding opposite the flow in the run winding.
Fig. 2-9
2. The motor is coupled directly to the transmis-
sion and will cause the transmission shaft to
turn in the agitate direction. The agitator is
mounteddirectlytothe transmission shaftand
is driven back and forth to provide agitation.
3. The water pump is mounted directly to the
motor and will also turn in the agitate direc-
tion. At this point the pump is running in re-
verse, so water does not leave the tub.
4. During the agitation cycle, the wash water is
being pulled through a basket mounted lint
filter, (if equpped), by pumping vanes molded
into the underside of the agitator. Due to the
shape of the filter, lint is captured on the filter
fins.
5. Also, during the agitation cycle, the transmis-
sion is being set up for neutral drain to pro-
vide a pump-out prior to going into spin.
6. Once the timer has advanced to the end of
the wash cycle, contacts open in the timer
causing the drive motor to stop.

2. The drive motor now turns the pump in the clockwise or drain direction causing the pump to drain
the dirty water out of the tub through the drain hose.
3. The weight of the water being pulled over the lint filter flushes the lint from the filter and out the
drain hose with the dirty water.
4. After a two-minute drain, the timer contacts open momentarily, stopping the drive motor. This
momentary pause causes the transmission to reset itself for the spin cycle.
1. The timer advances to the next step in the process, which is the drain cycle. This time, contacts 14
in the timer are closed, energizing the drive motor to run in a clockwise direction. The current flow
in the start winding is the same as that in the run winding.
