Install Drain Nozzle
1. Remove cardboard inner pack and installation accessories from under lid. Drain hose is in
washer basket.
2. Grasp retainer rod
on lower right side
(has a tag on strap),
and pull rod straight
out and discard.
3. Be sure water supply lines have been
thoroughly flushed.
4. Move washer to final
location. DO NOT let fill or drain hoses drag and
get under washer.
5. Adjust front leveling legs as necessary to level
washer. Front leveling legs are adjustable; if
adjustment is
necessary, relevel. The washer
must rest firmly
on all four legs.
To “set” rear selfleveling system,
tip washer forward so that rear
base is about 4"
off the floor, then lower.
6. Install drain hose in drain facility and secure with
plastic tie strap provided or tape as illustrated.
Note: Drain hose nozzle may be shortened if original
length prevents full insertion into drain facility.
1. Insert one end of aluminum drain nozzle into
standpipe.
2. Slip or cut wire wrap back approximately 2" below
top of standpipe.
3. Cut drain hose just below standpipe. Place silver
hose clamp over black drain hose end.
4. Insert drain nozzle
into end of drain
hose, and
position clamp to
secure drain nozzle
to drain hose.
CAUTION: Be sure drain hose is taped or secured to
standpipe or other drain facility.
Note: Water may be drained into a standpipe. The
discharge height must not be less than 30 inches, nor
more than 6 feet above base of washer. Standpipe
must be 1-1/2" minimum inside diameter and must
be open to atmosphere.
Economy Water Usage
The pressure switch is set in the factory for the
medium water level and usage.
To change setting from medium water level to high
or low:
1. Make sure washer is unplugged from electrical
outlet.
2. Remove 4 torx screws from back of control panel
and lay control panel front on cover.
CAUTION: Be sure drain hose is firmly secured to
drain facility.
7. Determine which is HOT water line before
attaching fill hoses to faucets. Traditionally, HOT
faucet is on the left. Be sure rubber washers are
in end of both washer fill hoses and connect
hose from right inlet valve on washer (marked
HOT) to HOT faucet and left hose to COLD faucet.
Couplings should be hand-tightened plus 1/2
turn with pliers.
3. Locate pressure switch in backsplash, and per
illustration move white plastic cam on pressure
switch to the clockwise position with your finger,
until it clicks into position, to select the economy
water saver (low water level). To select high
water level, move the white plastic cam counterclockwise until it clicks into position. Pressure
switch does not have to be removed to change
the setting.

Lint Removal System
The lint filtering system consist of the turbo pump,
agitator, air bell, and self cleaning filter at bottom of
spin basket. During agitate water moves through
the sides and up from the bottom through the self
cleaning filters.
During pump down, prior to spin, the turbo pump
is energized, and water is drawn out the sides and
down through the self cleaning filter to clean and
remove lint from the bottom side of the filter area,
and flush lint down the drain.
Energy Saving
All wash cycles include energy-saving cold water
rinse.
Total Cycle Time
27 minute wash cycle, plus fill time. Wash time is

The control panel is designed with ease of service
being the major consideration. The switches are tab
interlock, and harness connectors are designed to
only fit the correct mating connector. Control panel
is galvanized, with three tabs designed to allow the
switchtrim to be supported during service. MiniManual is located in the control panel.
1. Remove four (4) T20H Torx screws from the top
of control panel as shown. (Mini-Manual can be
accessed from this position as illustrated.)
2. Water valve is serviceable by removing the (4)
T20H Torx screws from the top of the control
panel, and rotating the switchtrim forward. Two
1/4" hex screws mount the water valve to the
console. The water valve can be changed from
the front by first “pinching off” the inlet hoses
and pulling through back of control panel to
remove.
To Replace Countback Display PC Board:
(Some Models)
WARNING! THE STEP DOWN CAPACITOR
