Safety Information
Explanation of Safety Messages
Precautionary statements (“DANGER,” “WARNING,”
and “CAUTION”), followed by specific instructions,
are found in this manual and on machine decals. These
precautions are intended for the personal safety of the
operator, user, servicer, and those maintaining the
machine.
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.
Important Safety Instructions
1. Read all instructions before using the washer.
2. Refer to the GROUNDING INSTRUCTIONS in
the INSTALLATION manual for the proper
grounding of the washer.
3. Do not wash textiles that have been previously
cleaned in, washed in, soaked in, or spotted with
gasoline, kerosene, waxes, cooking oils, dry-
cleaning solvents, or other flammable or
explosive substances as they give off vapors that
could ignite or explode.
4. Do not add gasoline, dry-cleaning solvents, or
other flammable or explosive substances to the
wash water. These substances give off vapors that
could ignite or explode.
5. Under certain conditions, hydrogen gas may be
produced in a hot water system that has not been
used for two weeks or more. HYDROGEN GAS
IS EXPLOSIVE. If the hot water system has not
been used for such a period, before using a
washing machine or combination washer-dryer,
turn on all hot water faucets and let the water
flow from each for several minutes. This will
release any accumulated hydrogen gas. The gas is
flammable, do not smoke or use an open flame
during this time.
6. Do not allow children to play on or in the washer.
Close supervision of children is necessary when
the washer is used near children. This is a safety
rule for all appliances.
7. Before the washer is removed from service or
discarded, remove the door to the washing
compartment.
8. Do not reach into the washer if the wash drum is
moving.
DANGER indicates the presence of a
hazard that will cause severe personal
injury, death, or substantial property
damage if the danger is ignored.

Theory of Operation
The design of the machine emphasizes performance
reliability and long service life. The cylinder, shell,
and main body panels are fabricated of stainless steel.
The cylinder is driven by a belt-drive system supported
via the shaft by two flange-mounted spherical roller
bearings bolted to the A-frame. The UW35 uses a
trunion.
The machine uses one motor to drive the cylinder via a
V-belt drive in all speeds.
A door-lock system prevents opening of the stainless
steel door when water is in the machine. It also
prevents operation of the machine when the door is
open.
Electrically operated drain valves are used to retain the
water and wash solution in the machine during the
wash and fill steps. The drain valve closes when power
is applied and opens when power is removed, allowing
the machine to drain in the event of a power failure.
The cylinder is designed with lifters or ribs that lift the
garments from the wash solution when the cylinder
rotates at slow speed and allow the garments to tumble
back into the solution. The cylinder is perforated,
allowing the water to pass through and drain from
within during the wash process and extract.
Electrical controls for the machine are housed in a
separate enclosure located underneath the top cover of
the machine.
There are two possible load balance systems, the “AC
Inverter Drive Balance Detection” and the “Vibration
Safety Switch.”
The balance detection system using the vibration
safety switch does not rely on the AC inverter drive
and does not attempt to balance the load in a drain
step. As the cylinder is spinning at the programmed
speed, if the wash load becomes unbalanced, the
overtravel limit switch is “tripped” causing the
cylinder to slow to a stop. The remaining portion of the
cycle is aborted.
The balance detection system using the AC inverter
drive uses special balance detection software in
conjunction with the V-computer to prevent out-of-
balance conditions. When the AC drive detects an
unbalanced load during the drain step, the computer
will make up to three attempts to balance the load.
After the third try the machine spins at a safe speed up
to 106 G. As a fail-safe measure, a vibration safety
switch is installed.
The machine uses an AC inverter drive control which
provides five motor speeds using a single motor. The
solid state output board converts motor logic from the
V-computer to the correct signals for the AC inverter
drive.
The operator can select from among 30 cycles. A
special permanent test cycle can be selected to verify
proper operation of the machine.
Liquid supplies can be injected directly into the cups
by a customer-supplied external chemical supply
system. Five hose strain reliefs on top of the supply
dispenser facilitate connection to an external supply
system. A terminal strip inside a panel on the rear of
the control module provides connection points for
external supply signals.
V-Computer
The V-computer control is a programmable solid-state
control capable of storing and running up to 30 cycles.
A detailed description of these cycles can be found in
the Programmingsection of this manual.
If this machine’s computer has been equipped with
special preprogrammed cycles, a separate insert listing
these cycles has been included in the resealable plastic
bag which contained this manual.
NOTE: Never turn the power off while the
computer mode switch is in the Program position.
Such action will disorder portions of the
programmed data, necessitating reprogramming of
some or all of the existing cycles. Always return the
mode switch to Run position before turning the
power off. Refer to the Programming Manual.

Keypad
Operation of the V-computer control is performed with
a four-key touch keypad and LED display located on
the front of the machine. Refer to Figure 3.
Figure 3
Table 1 describes the function of the individual keys
when the machine is in Run Mode.
Table 1
Conditions Monitored by the Computer
●Door – The computer continuously monitors
the open/locked status of the door. If it detects
that the door is open during a wash cycle, it
immediately aborts the cycle and executes the
stop routine.
●Power – If power is interrupted long enough
for the computer to go off, after the power is
restored, the display flashes “Hold” briefly to
indicate the interruption. The door unlock will be
disabled to keep the door from being opened
while the basket is still turning.
●Balance – During a regular cycle, the computer
monitors the balance signal provided by the AC
drive during drain steps. The computer will
attempt to distribute the load three times. The dot
at the top of the leftmost display digit will light
following the final unsuccessful attempt.
●Water level – The computer attempts to maintain
the water level programmed for the fill preceding
the agitation step. If the level falls below the
programmed level, the computer will stop the
time countdown and re-energize the fill valves
until the level is restored.
●Water level in a heat step – In order for the
computer to energize the heat output, there must
be at least a low water level in the machine. If this
minimum level is not detected, the heat output
will be turned off until the required level is
restored.
●Temperature probe problem – If the
temperature sensor fails when prompted for
degrees Fahrenheit, the computer flashes “tSFL”
in Program Mode rather than showing the
temperature. If the temperature sensor fails when
prompted for degrees Celsius, the display will
read “-17C” rather than showing the temperature.

Start-Up
IMPORTANT: Remove all sharp objects from
laundry to avoid tears and rips to items during
normal machine operation.
Turn on the main power source (circuit breaker or cut-
off switch on the wall).
An identification code will appear for approximately
five seconds. Then the display will flash “Hold”
briefly.
The display will then read “CY” followed by a two-
digit cycle number (01 – 30) to indicate that a cycle
can be selected. This display will be shown at all times
when power is on between cycles, indicating that the
door-unlock solenoid will function if the door-unlock
button is pressed. Run the Test Cycle before operating
the washer-extractor. Refer to Test Cycle in the
Programming Manual. The machine is then ready for
loading and unloading.
Opening Door
Press and hold the door-unlock button and pull door
handle clockwise.
Loading
Load the machine to full capacity whenever possible,
but do not exceed the rated dry-weight capacity of the
machine if the fabric to be washed is quite dense,
closely woven, and heavily soiled. Overloading can
result in an inferior wash. Underloading can result in
poor load distribution potentially causing the extract
speed to be limited. The operator may need to
experiment to determine load size based on fabric
content, soil content, and level of cleanliness required.
NOTE: Underloading can cause out-of-balance
conditions which shorten life of bearing, seals,
basket/shaft assembly, etc.
When loading is complete, ensure that all fabric is
inside the basket. Then close and lock the door by
fully rotating the door handle counterclockwise. The
machine should not start or run unless the door is both
closed and locked.
NOTE: When washing items which may
disintegrate, such as mop heads or sponges, use
laundry net bags to prevent drain blockage.
Cycle Selection
NOTE: Press keys at their centers just hard enough
to activate them.
Press the Up or Down key until the desired cycle
number is displayed. The computer will skip blank
(unprogrammed) cycles automatically. Press the Start
key to start the cycle. For a more detailed description
of the preprogrammed cycles, refer to the cycle charts
at the end of the Programming Manual.
If the computer detects that the door is not properly
closed when the Start key is pressed, the display will
read “door” until the door is closed and locked. Press
Start again to begin the desired cycle.
Be careful around the open door,
particularly when loading from a level
below the door. Impact with door edges
can cause personal injury.
SW025
CAUTION
Never operate the machine with a
bypassed or disconnected balance
system. Operating the machine with
severe out-of-balance loads could result
in personal injury and serious equipment
damage.

Cycle Execution
A cycle can be stopped at any time by pressing the
Stop key. The machine will go to the stop routine.
When the routine is complete, the display shows
“donE” until the door is unlocked.
To display the temperature of the water while a cycle
is running, press the Up key. To display the number of
the cycle in progress, press the Start key.
NOTE: The computer does not count down the
remaining cycle time during fills, drains, cool-
down, or prior to first achieving the programmed
heat temperature when heating. The computer
resumes counting down cycle time once the
programmed fill level is reached, when the machine
has drained, and after a programmed heat
temperature is reached.
Each of the 30 cycles consists of 11 segments:
PreWash, Wash, and Fills 1 – 9. A description of the
various steps in a cycle segment follows:
Fill
After the Start key is pressed, the drain closes and the
machine begins filling to the programmed level. Each
programmed segment begins with a fill. The display
counts down the remaining cycle time in minutes and
seconds while the cycle is running.
If a supply is programmed in a step, the supply
dispenser will flush during the fill of that segment.
If the machine is connected to an external chemical
supply system, the programmed supply will begin
10 seconds into the fill. The supply will remain on
until the programmed water level is reached, or until
60 seconds have elapsed, whichever happens first.
If agitation options 1 or 2 are selected for the cycle
program, the cylinder will rotate slowly during the fill
step. If agitation options 3 or 4 are selected for the
cycle program, the cylinder will not rotate during the
fill step. Refer to Table 3 for more information.
If the computer does not receive a signal that water
level has been attained within 30 minutes, it will
alternately flash “STOP” and “FILL” and sound the
on-board beeper for ten seconds. The computer will
then initiate the stop routine.
Wash
As soon as water level is reached (and any
programmed temperature is reached), the displayed
time begins counting down at one-second intervals.
Agitation is active during this portion of the segment.
There are four different agitation actions available.
Refer to Table 3 for more information.
Table 3
If the segment contains a heat step, the machine begins
heating after the water has reached the programmed
level.
NOTE: If the water does not reach the
programmed temperature in 40 minutes, the
computer progresses to the wash step.

F232183
Drain
If the cycle program segment calls for a drain, the
drain valves will open after the programmed segment
time has elapsed. If a spin step follows a drain step, the
cylinder will turn clockwise (forward) at wash speed
for several seconds at the beginning of the drain step.
This clockwise direction mirrors the spin rotation and
is, therefore, also considered forward.
The cylinder then accelerates to distribution speed to
help ensure that the load is evenly distributed. The
drains open several seconds later.
NOTE: The machine should drain in 30 seconds. If
the machine fails to drain, contact a qualified
service technician.
If the cycle program segment does not call for a drain,
the computer moves to the next segment of the cycle
program. If the segment is at the end of a cycle
program, the computer goes into the stop routine.
If the cycle program segment does not call for a spin,
the cylinder will continue to turn at wash speed
throughout the drain step. When the drain has
completed, the computer moves to the next segment of
the cycle program. If the segment is at the end of a
cycle program, the computer goes into the stop
routine.
NOTE: The drain step in the final segment (Fill 9)
cannot be skipped.
Spin
After the drain sequence ends, the speed of the
cylinder increases to the extract speed if the
programmed spin time is not zero. The displayed time
resumes counting down at one-second intervals.
After the programmed spin time has elapsed, the
computer moves on to the fill step in the next segment
of the cycle. If the spin is at the end of the cycle, the
computer begins the stop routine.
Stop Routine
When the computer concludes the wash cycle or when
the Stop key is pressed while a cycle is in progress, the
computer goes into the stop routine.
The stop routine sequence:
●All inputs are turned off
●A brief pause, allowing the cylinder to coast
down if in extract
●Brief rotation counterclockwise at wash speed
●A brief pause
●Brief rotation clockwise at wash speed
●A brief pause
●The display shows “donE”
●The door interlock is energized, allowing the
door to be opened
If the stop routine seems excessively long, check for
“FULL” message. If this occurs, contact a qualified
service technician.
Once “donE” is displayed, open the door by pressing
and holding the door-unlock button as described
earlier. Once the door is opened, the computer display
will show the most recent cycle number.
The machine is now ready to begin another wash
cycle.
NOTE: A test cycle is provided as a means of
verifying proper machine operation. Refer to the
Programming Manual for instructions on running
the test cycle.

Balance Detection
Each machine is equipped with an AC inverter drive
balance detection system and a vibration safety switch.
Load balance is monitored by the AC inverter drive
during any drain step that immediately precedes a spin
step in a regular cycle.
If a spin step follows a drain step, the cylinder
accelerates to distribution speed seven seconds into the
drain step.
The computer begins monitoring the balance signal
from the AC inverter drive soon after the water level
drops below low level. If the balance signal indicates
that the wash load is evenly distributed, the computer
will start the spin step.
If the balance signal indicates that the wash load is
unbalanced, the computer will turn off the motor for
about four seconds, then will operate the cylinder
down to wash speed for seven seconds in an attempt to
redistribute the load. The computer will make as many
as three attempts if needed.
If on the third attempt the load is not balanced, the
machine will light the out-of-balance LED indicator
located in the upper left corner of the display (to the
left of the first digit) until the drain and following spin
conclude. The computer will limit the spin speed to a
safe level.
As a fail-safe measure, a vibration safety switch will
“trip” during a spin if the wash load becomes severely
unbalanced, slowing the cylinder to a stop and
aborting the remaining portion of the cycle. The
computer display will alternately flash “BAL” “door”
until the door is opened.
Motor Thermal Overload Indicator
If the machine is equipped with a small indicator lamp
on the side of the control module, it will light to
indicate that a thermal overload switch in the motor
has shut off the AC power to the computer board,
thereby preventing damage to the motor caused by
overheating and/or an overload condition. This feature
protects and extends the life of the motor.
The thermal overload switch will automatically reset
itself after the excessive heat condition has subsided.
Before attempting to restart the washer-extractor,
determine the reason for the overload. The following is
a partial list of possible problems:
●Washer-extractor not fully drained before spin
●Out-of-balance condition
●Low voltage
●Loss of one phase on a three-phase motor
●Bad bearings
●Air circulation blocked to motor
Contact a service technician to correct serious
problems. Failure to take corrective action will
ultimately result in damage to the motor and/or the
inverter drive.

Maintenance
Routine maintenance maximizes operating efficiency
and minimizes downtime. The maintenance
procedures described below will prolong the life of the
machine and help prevent accidents.
Daily, weekly, monthly, and quarterly checklists are
provided at the end of this section. Laminate the
checklists to preserve them for repeated copying.
Operators and technicians are encouraged to add
checks specific to their washer-extractor’s particular
application. Where possible, space is provided on the
checklists for this purpose.
The following maintenance procedures must be
performed regularly at the required intervals.
Daily
Beginning of Day
1. Inspect water inlet valve hose connections on the
back of the washer-extractor for leaks.
2. Inspect steam hose connections for leaks (where
applicable).
3. Verify that insulation is intact on all external
wires and that all connections are secure. If bare
wire is evident, call a service technician.
4. Check door interlock before starting operation:
a. Attempt to start the washer-extractor with the
door open. The washer-extractor should not
start with the door open.
b. Close the door without locking it and attempt
to start the washer-extractor. The washer-
extractor should not start with the door
unlocked.
c. Close and lock the door and start a cycle.
Attempt to open the door while the cycle is in
progress. The door should not open.
If the door lock and interlock are not functioning
properly, call a service technician.
Be careful when handling sheet-metal
parts. Sharp edges can cause personal
injury. Wear safety glasses and gloves,
use the proper tools, and provide
adequate lighting.

End of Day
1. Clean the AC drive box filters:
a. Snap off the external plastic cover which
contains the filter.
b. Remove the foam filter from the cover.
c. Wash the filter with warm water and allow to
air dry. Filter can be vacuumed clean.
2. Clean the door gasket of residual detergent and
all foreign matter.
3. Clean automatic supply dispenser and lid inside
and out with mild detergent. Rinse with clean
water.
4. Clean powder dispenser and lid with mild
detergent. Rinse with clean water.
5. Clean washer-extractor’s top, front, and side
panels with mild detergent. Rinse with clean
water.
6. Leave loading door open at the end of each day to
allow moisture to evaporate.
NOTE: Unload the washer-extractor promptly
after each completed cycle to prevent moisture
buildup. Leave loading door open at the end of each
completed cycle to allow moisture to evaporate.
Weekly
1. Check the washer-extractor for leaks.
a. Start an unloaded cycle to fill the washer-
extractor.
b. Verify that door and door gasket do not leak.
c. Verify that the drain valve is operating and
that the drain system is free from obstruction.
If water does not leak out during the prewash
segment, drain valve is closed and functioning
properly.
Monthly
NOTE: Disconnect power to the washer-extractor
at its source before performing the monthly
maintenance procedures.
1. Each month OR after every 200 hours of
operation, lubricate bearings. (Locate the bearing
lubrication decal at the rear of the left side of the
control module, as viewed from the front of the
washer-extractor.)
The grease must have the following
characteristics:
●NLGI Grade 2
●Lithium-based
●Water-insoluble
●Anti-rusting
●Anti-oxidizing
●Mechanically stable
