LOCATION REQUIREMENTS
Selecting the proper location for your washer
improves performance and minimizes noise
and possible washer “walk.” Your washer can
be installed under a custom counter, or in a
basement, laundry room, or recessed area.
Companion appliance location requirements
should also be considered. Proper installation
is your responsibility. You will need
A water heater set to deliver 120°F (49°C)
•
water to the washer.
A grounded electrical outlet located within
•
6 ft (1.8 m) of where the power cord is
attached to the back of the washer.
(See page 2-5).
Hot and cold water faucets located within
•
4 ft (1.2 m) of the hot and cold water fill
valves, and water pressure of 20-100 psi
(137.9-689.6 kPa).
A level floor with a maximum slope of 1”
•
(25 mm) under entire washer. Installing
the washer on soft floor surfaces, such as
carpets or surfaces with foam backing, is
not recommended.
A sturdy and solid floor to support the
•
washer with a total weight (water and load)
of 400 lbs (180 kg).
Do not operate your washer in temperatures
below 32°F (0°C). Some water can remain
in the washer and can cause damage in low
temperatures.
Installation clearances
The location must be large enough to allow
•
the washer door to be fully opened.
Additional spacing should be considered for
•
ease of installation and servicing. The door
opens more than 90° and it is not reversible.
Additional clearances might be required for
•
wall, door, and floor moldings.
Additional spacing of 1” (25 mm) on all
•
sides of the washer is recommended to
reduce noise transfer.
Companion appliance spacing should also
•
be considered.

DRAIN SYSTEM
The washer can be installed using the
standpipe drain system (oor or wall), the
laundry tub drain system, or the oor drain
system. Select the drain hose installation
method needed.
Standpipe drain system: wall or oor
(Views A & B)
The standpipe drain requires a minimum
diameter standpipe of 2” (50 mm). The
minimum carry-away capacity can be no less
than 10 gal. (38 L) per minute.
The top of the standpipe must be at least 30”
(762 mm) high and no higher than 96” (2.4 m)
from the bottom of the washer. A drain hose
extension must be added to reach maximum
drain height capability.
Laundry tub drain system (view C)
Laundry tub needs a minimum 20 gal. (76 L)
capacity. The top of the laundry tub must be
at least 30” (762 mm) above the oor.
Floor drain system (view D)
The oor drain system requires a siphon break
that may be purchased separately.
The siphon break must be a minimum of 28”

Electrical Shock Hazard
Plug into a grounded 3 prong outlet.
Do not remove ground prong.
Do not use an adapter.
Do not use an extension cord.
Failure to follow these instructions can
result in death, fire, or electrical shock.
A 120 volt, 60 Hz., AC only, 15 or 20
•
amp, fused electrical supply is required.
A time-delay fuse or circuit breaker is
recommended. It is recommended that a
separate circuit serving only this appliance
be provided.
Export models require a 220 / 240 volt, 50
•
Hz, AC power supply and a 10 or 15 amp
circuit breaker or time delay fuse. It is
recommended that each washer be on its
own circuit.
This washer is equipped with a power
•
supply cord having a 3 prong grounding
plug. Export models have various power
cord adapters available for use.
To minimize possible shock hazard, the
•
cord must be plugged into a mating, 3
prong, grounding-type outlet, grounded
in accordance with local codes and
ordinances. If a mating outlet is not
available, it is the personal responsibility
and obligation of the customer to have the
properly grounded outlet installed by a
qualified electrician.
If codes permit and a separate ground wire
•
is used, it is recommended that a qualified
electrician determine that the ground path is
adequate.

•
Check with a qualified electrician if not sure
•
that the washer is properly grounded.
Do not have a fuse in the neutral or ground
•
circuit.

if you are in doubt as to whether the
appliance is properly grounded.
Do not modify the plug provided with the
appliance – if it will not t the outlet, have
a proper outlet installed by a qualied
electrician.
For a permanently connected washer:
This washer must be connected to
a grounded metal, permanent wiring
system, or an equipment grounding
conductor must be run with the circuit
conductors and connected to the
equipment-grounding terminal or lead on
the appliance.

Replace all parts and panels before
operating.
Failure to do so can result in death or
electrical shock.
Electrostatic Discharge (ESD)

ESD problems are present everywhere.
ESD may damage or weaken the
electronic control assembly. The new
control assembly may appear to work
well after repair is nished, but failure
may occur at a later date due to ESD
stress.
GENERAL USER
INFORMATION
Scrolling “out of order” message followed by a
Failure Code:
This condition showing in the display indicates
the washer is in an inoperative state and
requires service. The failure code displayed is
the best indication of the reason the washer
has become inoperative.
‘0 Minutes’ showing in display:
This condition indicates the appliance cannot
be operated. Coins dropped or debit inputs
during this condition will be stored in escrow
but cannot be used until normal operation is
restored by opening and closing the door. If
a door switch has failed, it must be replaced
before normal operation can be restored.
Cold Start (initial rst use):
Appliance is programmed at the factory as
follows:
11 minute wash period
n
Use an anti-static wrist strap. Connect
n
wrist strap to green ground connection
point or unpainted metal in the
appliance.
-OR-
Touch your finger repeatedly to a green
ground connection point or unpainted
metal in the appliance.
Before removing the part from its
n
package, touch the antistatic bag to
a green ground connection point or
unpainted metal in the appliance.
Avoid touching electronic parts or
n
terminal contacts; handle electronic
control assembly by edges only.
When repackaging failed electronic
n
control assembly in antistatic bag,
observe above instructions.
3 rinses (extra rinse not enabled)
n
$1.75 wash price (PD models)
n
$0.00 wash price (PR Models)

Door Lock
NOTE: Not displayed on washer as shown. Message scrolls
followed by the failure code.
Door lock does a Child Safety Routine at start
of every cycle. Child Safety Routine is: Lock,
turn spin basket 1/2 revolution, Unlock, then
Relock. The door will be locked when the
cycle starts. The door will remain locked until
the end of a cycle or approximately 2 minutes
after a power interruption.
NOTE: If power is interrupted prior to 2
minutes of operation the automatic door
unlocking mechanism may fail, and door will
remain locked until the power is restored or
the lock is manually opened by pulling on the
safety release tab.
(See page 4-17)
Free Cycles
This is established by setting the cycle price to
zero. When this happens, ‘SELECT CYCLE’
will be displayed rather than a cycle price.
Debit Card Ready
This washer is debit card ready. It will accept
a variety of debit card systems, but
DOES NOT come with a debit card reader.
Refer to the debit card reader manufacturer for
proper washer set-up. In models converted to
a Generation 1 debit card system, each debit
pulse represents the equivalent of one coin
(Coin 1).
Display
After the washer has been installed and
plugged in, the display may show
‘0 MINUTES’. Once the washer has been
plugged in and the washer door opened and
closed, the display will show the cycle price
or amount of coins needed to start a cycle. If
Super Cycle is enabled the Regular price and
Super Cycle price will alternate in the display.
In washers set for free vend, the display will
ash ‘SELECT CYCLE’ rather than a cycle
price.
Pricing in the display
After the door is opened following the
completion of a cycle, the display indicates the
cycle price (unless set for free operation). As
coins are dropped or debit inputs arrive, the
display will change to lead the user through
the initiation of a cycle.
During a cycle the display will show the
approximate time remaining unless the
washer is going through a “Suds Removal
Routine.” During the routine the display will
alternate between the word “SudS” and the
time remaining in the routine. At the end of
the 5 minutes needed for this routine, the
display returns to the same time displayed
prior to entering it.
