GENERAL USER INFORMATION
Scrolling ‘out of order’ message, followed by a failure
or diagnostic code, showing in display
This condition indicates the washer/dryer is inoperative. Diagnostic
codes being displayed on the upper portion of the display pertain
to the dryer section, and diagnostic codes displayed on the lower
portion of the display apply to the washer section. Diagnostic codes
displayed on both the upper and lower portions of the display
pertain to the control system of both the washer and dryer.
Cold Start (initial use):
‘0 Minutes’ showing in display
This condition indicates the cycle is complete and the washer/dryer
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, causing ‘0 MINUTES’ to remain in the display
after the door is opened and closed, it must be replaced before
normal operation can be restored.
Warm Start (after power failure):
A few seconds after power is restored, if a cycle was in progress
at the time of the power failure, ‘RESELECT CYCLE’ will flash
in the display, indicating the need for a key press to restart
the washer or dryer.
Washer is programmed at the factory as follows:
n
11 minute wash period
n
3 rinses (extra rinse not enabled)
n
$2.00 wash price
Dryer is programmed at the factory as follows:
n
5 minutes per quarter
n
$1.50 dry price
Washer Door Lock
Prior to beginning a cycle, there is a door lock routine of lock/
unlock/relock, then cycle begins. The door will remain locked
until the end of a cycle or approximately 2 minutes after a
power interruption.
Pricing
After the door is opened and then closed following the completion
of a cycle, the display indicates the cycle price (unless set for free
operation, where the display will flash ‘SELECT CYCLE’). As coins
are dropped or debit inputs arrive, the display will change to lead
the user through the initiation of a cycle.
There are four (4) types of dryer pricing:
Fixed ‘Vend’ Pricing
A dryer set up for ‘Fixed Cycle’ operation can only accept
additional time accumulated by increments equal to the length
of a complete dry cycle. A maximum of 99 minutes may be
purchased; no additional credit is given for coins dropped
with 99 minutes in the display.
Accumulator Pricing
If the price is set to one coin 1, then accumulator pricing is in effect.
Cycle time can be purchased one coin at a time up to the maximum
time of 99 minutes.
Fixed Cycle With Top Off Pricing
A dryer set to offer ‘Top Off’ capability will allow time to be added
to an existing dry cycle in increments equal to the number of
minutes of dry time per quarter (coin 1), up to 99 minutes, regardless
of the cost required to start the dryer. No credit is given for coins
or debit inputs entered when the control is displaying 99 minutes.
With Card Payment System: In Enhanced Debit Mode, the top off
price can be set independently (see VALUE OF COIN 2), and the top
off time is calculated according to the following equation:
full cycle price
top off time =
top off price
x full cycle length
Penny increment offset is not applied to top off purchases.
Free Cycles
This is established by setting the cycle price to zero. When this
happens, ‘SELECT CYCLE’ will appear rather than a cycle price.
Any cycle started as a free cycle will automatically terminate
when the door is opened.

Debit Card Ready
This washer/dryer 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/dryer
set-up. In models converted to a Generation 1 debit card system,
debit pulses represent the equivalent of one coin (coin 1).
CONTROL SET-UP PROCEDURES
IMPORTANT: Read all instructions before operating.
n
Coin Payment Models: Insert service switch key and turn
counter-clockwise.
n
With Card Payment System: Once a Generation 2 debit card
reader is installed (according to the reader manufacturer’s
instructions), the set-up modes can be changed by inserting a
set-up card (supplied by the reader manufacturer) into the card
slot. Inserting the service switch key and turning will only access
the service mode.
The washer/dryer is now in the set-up mode. The bottom
temperature setting buttons and the lower portion of the display are
used to set up the digital control for the washer. The upper three
fabric setting buttons and the upper portion of the display are used
to set up the controls for the dryer.
The display can contain four numbers and/or letters and a decimal
point on both the top and bottom display portions. These are used
to indicate the set-up codes and related code values available for
use in programming the washer/dryer.
Start Operating Set-Up
Washer/dryers are preset at the factory and do not require any
programming. However, if you want to change the settings, follow
the ‘Set-Up Codes’ guide.
The first code shown in each segment is the factory default setting.

DIAGNOSTIC GUIDE
Before servicing, check the following:
n
Make sure there is power at the wall outlet.
n
Verify that both hot and cold water faucets are open and water
supply hoses are unobstructed.
n
Check all connections before replacing components. Look for
broken or loose wires, failed terminals, or wires not pressed
into or onto connections far enough.
n
A potential cause of a control not functioning is corrosion on
connections. Observe connections and check for continuity
with an ohmmeter.
n
Connectors: Look at top of connector. Check for broken or loose
wires. Check for wires not pressed into connector far enough
to engage metal barbs.
n
Resistance checks must be made with power cord unplugged
from outlet, and with component connectors disconnected.
DIAGNOSTIC MODE
To enter the ‘Diagnostic Mode,’ first enter ‘Start Operating Set-Up.’
Then press and hold the lower right (COLD) button for 1 second
while in set-up code six, anytime a diagnostic code is present, or while
dAS displays if operating with a Generation 2 card reader.
On entry to diagnostic mode, the entire display will flash, a cycle
in process is canceled, money in escrow is cleared, and diagnostic
codes are cleared. If a diagnostic code persists on the portion of
the washer/dryer not being tested, it can be acknowledged with the
lower middle (WARM) button prior to starting a diagnostic cycle.
This would be used when, for example, the dryer is out of service
and a diagnostic cycle is to be run on the washer.
There are six possible ways to initiate cycle activity from diagnostic
mode as follows:
1. Washer Cleanout Cycle – With the entire display flashing,
this cycle is started by pressing the center right (COLORS/
DELICATES) button.
Use the Washer Cleanout Cycle once a month to keep the inside
of your washer fresh and clean. This cycle uses a higher water
level. Use with liquid chlorine bleach to thoroughly clean the
inside of your washer. This cycle should not be interrupted.
IMPORTANT: Do not place garments or other items in the
washer during the Washer Cleanout Cycle. Use this cycle
with an empty wash drum.
2. Washer Cycle Credit – With the entire display flashing, a cycle
may be credited by pressing the lower left (HOT) button (CC will
display). When the service mode is exited, ‘SELECT CYCLE’ will
be displayed unless the end-of-cycle door opening is required.
3. Washer Manual Overview Test Cycle – With the entire display
flashing, this cycle is started by pressing the center left (COTTON/
WHITES) button. This cycle provides more typical full length fills,
tumbles, and drains, and allows for a more thorough analysis of
the washer operation, including pressure sensor behavior.
4. Washer Quick Spin Cycle – With the entire display flashing, this
cycle is started by pressing the center middle (PERM PRESS)
button. This cycle provides a method to quickly drain and spin
(remove water from the washer), if desired.
5. Washer Quick Overview Test Cycle – With the entire display
flashing, this cycle is started by pressing the lower middle
(WARM) button. This cycle provides a quick verification that
the cold and hot water valves, dispenser, and pump motor are
working. It also includes door lock, drain, and spin operations.
6. Dryer Field Diagnostic Cycle – With the entire display flashing,
this cycle is started by pressing the upper middle (PERM PRESS)
button. Additional time can be added by pressing the upper left
(COTTON/WHITES) button. This cycle can be used to credit lost
customer dryer time.
Pressing the lower right (COLD) button will exit diagnostic mode
and cancel a diagnostic cycle in process.

WASHER CCU ERROR
Communication error within the Central Control Unit
(CCU); the pump drive in CCU fails to activate; one of
the main relays in the CCU fails to activate.
Possible Causes
– A power surge/drop.
– Reversed polarity or mis-wire, along with open
ground switches.
Surge/drop procedure
1. Clear error code.
2. Unplug washer or disconnect power.
3. Wait 2 minutes before reconnecting power.
4. Verify CCU by running a short diagnostic test.
Mis-wire or reversed polarity procedure
1. Clear error code.
2. Check outlet for correct polarity. To check within
washer for polarity at the RFI, white to cabinet
ground must be 0 volts.
3. Check the white wire on the RFI filter to ensure correct
polarity. White wire needs to be toward front of washer.
If the RFI filter is not easily accessible, the polarity test
can be made on the washer CCU. Disconnect power.
Check for resistance or continuity at IF2 from terminal
#1 to ground or any bare metal on the washer cabinet.
Reading should be infinite or show as an open circuit.
4. Check that the ground switches of the toe panel
and rear panel are correctly closed.
5. Verify CCU by running a short diagnostic test.
If these procedures do not correct the failure, replace
the CCU control.
ACCELEROMETER FAILURE
The accelerometer component failed. The X, Y, and Z
limits are outside of the normal range.
Possible Causes
– CCU dislodged from mounting.
– Accelerometer failure on CCU.
MCU ERROR

Possible Causes
– A repeating under or overvoltage condition. If the
failure occurs during a high-speed spin, the door
remains locked for 2 minutes.
– A broken drive belt.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Using Ohm meter, check wire harness connections
for continuity between drive motor and the MCU.
4. Check the motor and do a continuity test (page 15).

try three times before the failure code is activated.
Possible Causes
– No water to washer; faucet(s) turned off.
– Defective hot and/or cold valve(s).
– Plugged or kinked inlet hoses or valves.
– Pressure sensor or pressure sensor hose
damaged, kinked, or disconnected.
– Electrical connection from CCU (PS8) to pressure
sensor damaged.
– Drain hose forced down into standpipe > 6" (152 mm).
– Blocked inlet from dispenser to tub.
Procedure
1. Clear error code by opening and closing the main
door or by power cycling the control by removing
power and then reestablishing power to the control.
2. Unplug washer or disconnect power.
3. Check incoming water pressure at faucet.
4. Check inlet hoses for possible leaks.
5. Make sure pressure sensor hose is in good condition
and properly connected to tub and pressure sensor.
6. Verify that water is not running out of the drain hose
(siphoning) as it is filling.
7. Perform continuity test on wire harness connections
from CCU to inlet valves (VCH7 and VSF2), and to
pressure sensor (PS8).
8. Check inlet valves by running a diagnostic test.
9. Check that the pump is not running while the
washer is filling.
10. Verify pressure sensor operation by accessing
Help Mode while running a paid cycle (see Help
Mode Symbols and Elements, page 14).
LONG DRAIN
The drain time exceeds 8 minutes without reaching
empty level in pressure sensor.
NOTE:
n
Suds can cause delays in draining, indicated by an

TROUBLESHOOTING GUIDE
PROBLEM POSSIBLE CAUSE/TEST
NOTE: Possible Cause/Tests must be performed in the sequence shown for each problem.
BLANK DISPLAY Possible Causes
– UIC not powered or no power to the washer/dryer.
– Wrong communication between CCU and UIC.
Procedure for UIC not powered
1. Check that the washer/dryer is plugged into a working outlet.
2. Unplug washer/dryer or disconnect power.
3. Check continuity from the power cord to the line filter.
4. Check continuity from the line filter to the transformer.
5. Perform Ohm meter test on the transformer (page 15).
Procedure for wrong communication
1. Unplug the washer/dryer or disconnect power.
2. Wait for 2 minutes.
3. Reconnect power.
If the display fails to turn on, replace the UIC.
TOUCH-PADS DO NOT RESPOND Possible Causes
WHEN PRESSED – Keypad ribbon disconnected, damaged, or contaminated, or installed with ribbon flap in wrong position.
– Door switch disconnected, loose, or damaged.
Procedure if matrix key board is disconnected
In this error, the keypad does not respond in any mode (normal operation, set-up, etc.).
1. Unplug washer/dryer or disconnect power.
2. Check that the keypad ribbon is connected to the UIC.
3. Clean the matrix keypad ribbon of soap or other residues.
4. Check the ribbon connector on the control board to see if there is corrosion on the contacts.
Verify the function of the keypad: perform keypad matrix test in service manual. If keypad fails to operate, replace it.
Procedure if door switch is disconnected
In this error, the keypad works normally in set-up mode, but will not start a user paid cycle.
1. Verify door switch operation by performing test for F26 error code (page 8), even if the F26 code is not displayed.
If the above procedures fail to solve the problem, replace the UIC.
WON’T DISPENSE 1. Verify that water is coming into the dispenser.
2. Verify that the washer/dryer is level.
3. Remove the insert and verify that the dispenser drawer is not clogged with detergent.
WASHER/DRYER VIBRATES 1. Verify that the washer/dryer is level.
2. Verify that the shipping system, including shipping bolts and spacers, is removed, and that the power cord
is not tangled in any components inside the rear of the washer/dryer.
3. Verify that the leveling legs are locked into place and firmly in contact with the floor.
4. Check for unbalanced load, especially when washing very small loads.
5. Verify that dampeners are all connected in place and not damaged.
6. Correct any twists in the door bellows.
7. Ensure proper drive belt placement on motor pulley.
8. Ensure that the washer/dryer is not installed on a wooden riser with a platform less than 3/4" (19 mm) thick.
DRUM WON’T ROTATE 1. Check for broken drive belt.
2. Check for drive motor failure error codes (F11, F25, F28).
• Check the electrical connection and verify the function of the cable between the MCU and drive motor.
3. Make sure that the door locks properly.
INCORRECT WATER TEMPERATURE 1. Make sure that the inlet hoses are connected properly.
2. Check the water temperature sensor for an abnormal condition (page 15). Make sure the hoses from the inlet
valves to the dispenser are connected properly.
3. Verify hot and cold water operation in Quick Overview Test in diagnostic mode.
4. Check for blocked filter screen in inlet valves.
