precautions:  
W023  
DANGER  
1. Read all instructions before using the washer.  
DANGER indicates the presence of a  
hazard that will cause severe personal  
injury, death, or substantial property  
damage if the danger is ignored.  
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.  
WARNING  
WARNING indicates the presence of a  
hazard that can cause severe personal  
injury, death, or substantial property  
damage if the warning is ignored.  
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.  
CAUTION  
CAUTION indicates the presence of a  
hazard that will or can cause minor  
personal injury or property damage if the  
caution is ignored.  
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.  
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.  
NOTE: The word “NOTE” is used to communicate  
installation, operation, maintenance or servicing  
information that is important but not hazard  
related.

basket until it has completely stopped.  
Doing so could result in serious injury.  
Environmental Conditions  
SW012  
Ambient Temperature. Water in the machine will  
To ensure the safety of machine operators, the  
following maintenance checks must be performed  
daily:  
freeze at temperatures of 32°F (0°C) or below.  
Temperatures above 120°F (50°C) will result in  
more frequent motor overheating and, in some  
cases, malfunction or premature damage to solid  
state devices that are used in some models.  
Special cooling devices may be necessary.  
1. Prior to operating the machine, verify that all  
warning signs are present and legible. Missing or  
illegible signs must be replaced immediately.  
Make certain that spares are available.  
Water pressure switches are affected by increases  
and decreases in temperature. Every 25°F (10°C)  
change in temperature will have a 1% effect on  
the water level.  
2. Check door interlock before starting operation of  
the machine:  
a. Attempt to start the machine with the door  
open. The machine should not start with the  
door open.  
Humidity. Relative humidity above 90% may  
cause the machine’s electronics or motors to  
malfunction or may trip the ground fault  
interrupter. Corrosion problems may occur on  
some metal components in the machine.  
b. Close the door without locking it and attempt  
to start the machine. The machine should not  
start with the door unlocked.

Safety Information  
This manual is designed as a guide to operating and  
maintaining the Pocket Hardmount washer-extractor  
equipped with the AC inverter drive.  
AC Inverter Drive  
Machines equipped with the AC inverter drive require  
special attention with regard to the operating  
environment.  
NOTE: All information, illustrations, and  
specifications contained in this manual are based  
on the latest product information available at the  
time of printing. We reserve the right to make  
changes at any time without notice.  
An especially dusty or linty environment will  
require more frequent cleaning of the AC inverter  
drive cooling fan filter and of the AC inverter  
drive itself.  
Power line fluctuations from sources such as  
uninterruptible power supplies (UPS) can  
adversely affect machines equipped with the AC  
inverter drive. Proper suppression devices should  
be utilized on the incoming power to the machine  
to avoid problems.  
A clean power supply free from voltage spikes  
and surges is absolutely essential for machines  
equipped with the AC inverter drive. Nonlinear  
inconsistencies (peaks and valleys) in the power  
supply can cause the AC inverter drive to  
generate nuisance errors.  
If voltage is above 240 Volt for 200 Volt  
installation, ask the power company to correct.  
As an alternative, a step-down transformer kit is  
available from the distributor. If voltage is above  
480 Volt for 400 Volt installations, a buckboost  
transformer is required.  
Sufficient space to perform service procedures  
and routine preventive maintenance is especially  
important for machines equipped with the AC  
inverter drive.

Operation  
vibration switch to detect an out-of-balance load, the  
switch will signal the WE-6 control to slow the motor  
speed, allowing the load to re-distribute, and then  
resume the spin speed programmed. The control will  
attempt to redistribute the load in this manner up to  
three times. On the third attempt, if an imbalance  
condition is still detected, the control will abort the  
spin speed step(s) and advance to the next non-spin  
speed step.  
Theory of Operation  
The design of the washer-extractor emphasizes  
performance reliability and long service life. The  
cylinder, shell, and main body panels are fabricated of  
stainless steel.  
Electrical controls for the washer-extractor are housed  
in a separate enclosure located on the top of the  
machine. Removing the screws from the module  
cover, lifting the cover, and pulling to the rear  
provides access to the control module. This module  
contains the WE-6 control, contactors, water-level  
switch, and other control components.  
However, if the washer-extractor is equipped with  
BOTH the vibration switch and the AC inverter drive  
balance detection systems, the function of the switch is  
slightly different. The inverter drive will monitor load  
imbalance conditions and the control. If the load is not  
balanced to spin at the programmed spin speed,  
control will attempt to re-distribute the load. After  
three unsuccessful attempts to balance the load,  
control will limit the spin speed (on models with the  
WE-6 Firmware ID Code of “ARWCxx” the WE-6  
display will alternately flash the programmed spin  
speed and the substituted spin speed). During the spin  
step, if the vibration switch detects a severe imbalance,  
due to improper installation or improper loading of the  
washer, the control will abort the remaining portion of  
the cycle and stop the machine. The display will flash  
“BAL/DR” while aborting the cycle until the door has  
been opened.  
The cylinder is driven by a V-drive system supported  
via the shaft by two flange-mounted spherical roller  
bearings bolted to the A-frame.  
The cylinder is constructed with four lifters or ribs that  
lift the laundry from the bath solution when the  
cylinder rotates at slow speed and then allow the  
laundry to tumble back into the bath. This mechanical  
action accomplishes the washing function. The  
cylinder is perforated, allowing the water to drain from  
within during the wash and extract steps.  
The spray rinse feature consists of a fiber-reinforced  
clear hose connected to the center of the door glass and  
to both a hot and cold water inlet valve. A  
hemispherically-shaped spray nozzle inside the door  
glass produces a fan-action water spray which  
disperses rinse water throughout the load.  
Water enters the washer-extractor through  
electromechanical water valves controlled by the  
microcomputer. The microcomputer also controls the  
drain and the door lock. In addition, it selects the water  
levels according to the programmed cycle. Vacuum  
breakers are installed in the water-inlet plumbing to  
prevent backflow of water.  
All UWPV washer-extractors use an AC inverter drive  
control which provides seven preset motor speeds  
using a single motor. The AC drive interface board  
converts motor logic from the WE-6 control to the  
correct signals for the AC inverter drive. In addition,  
all logic inputs to the control are routed through this  
board.  
The standard production UW35PV and UW60PV use  
a single drain valve. (Dual drains are available as an  
option.) The UW80PV, UW100PV, UW125PV and  
UW150PV use dual drain valves. The dual drains open  
and close together under control of the WE-6 control.  
The drain valve is normally open, which means that it  
closes only when power is applied, thus allowing the  
machine to drain in the event of a power failure.  
The operator can select from among 39 preprogrammed  
cycles. Cycle 39 is a test cycle used to verify proper  
operation of the washer-extractor. With the exception  
of Cycle 01, the remaining cycles are complete wash  
cycles or specialty cycles designed to handle various  
fabrics at specific water temperatures and levels.  
Cycle 01 is designed to test an external chemical  
injection supply system.  
A door-lock system prevents opening of the stainless  
steel door when a cycle is in progress. It also prevents  
operation of the washer-extractor when the door is  
open. The door box contains the door-lock  
microswitch, door-closed magnetic switch, and the  
door-unlock solenoid.  
Programmable custom cycles are another feature of  
the UWPV.  
The vibration switch system utilizes a micro-switch  
mounted between the faces of the A-frame to signal  
the WE-6 control that the load imbalance is too great  
for high extract speeds. Depending on the design  
series, the vibration switch will perform in either of  
two ways. If the washer-extractor utilizes ONLY the  
On later design models equipped with a rotation  
sensor, the door lock system will allow door to unlock  
soon after basket stops at the end of the cycle.

Operation  
The shaft seal assembly includes a collar held in place  
on the cylinder shaft with setscrews. The collar has a  
flange with a ceramic ring which makes contact with a  
spring-loaded face seal enclosed in a housing. The  
collar contains two internal O-rings which maintain  
contact with the cylinder shaft.  
LED Display  
The WE-6 control has a six-digit LED display.  
References to display indications pertain to the first  
four digits of the display reading left to right. The last  
two digits on the right side of the display will indicate  
either the last cycle used or the current cycle in  
progress. Refer to Figure 5.  
The polypropylene supply dispenser is mounted on the  
right side of the washer-extractor, viewed from the  
front. The dispenser has five supply compartments,  
numbered 1–5, starting from the rear of the machine.  
The compartments hold plastic supply cups that are  
used for either liquid or dry supplies. A nozzle flushes  
supplies from the cups with water for the time  
programmed in the cycle.

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 compartment  
attached to the left side of the control module, viewed  
from the rear of the washer-extractor, provides  
connection points for external supply signals.

Drain Steps  
Models that display WE-6 Firmware ID Code  
“ARWCO1” and later or “HRWC18” and later (i.e.  
“HRWC19”) after power up have two additional drain  
steps called “WASH DRAIN” and “Drain 5.” The  
steps provide a potential reduction in total cycle time  
because steps are shorter.  
WASH DRAIN” is used for draining to the sewer  
(“main” drain [drain 1]) when a spin step does not  
follow a “WASH DRAIN.” Any other steps (for  
example, fill step) may be programmed after a  
WASH DRAIN” step.  
“DRAIN 5” is identical to a “DRAIN 1” step, except it  
does not attempt to rebalance the load. “DRAIN 5” is  
recommended before a medium spin, a lower speed  
spin or a spray rinse step. Refer to Programming  
manual for additional details.

is inside the basket. Then close and lock the door.  
8. Add dry supplies are placed in the supply dispenser  
compartment cups prior to the start of each cycle.  
If the LED indicator lights for the control outputs  
indicate that one or more outputs are activated but the  
washer-extractor is not functioning according to the  
output or outputs indicated, contact a service  
technician.  
Liquid supplies can be injected directly into the supply  
dispenser by an external chemical supply system.  
NOTE: Supply dispenser compartment cups must  
not be removed when an external chemical  
injection supply system is attached to the washer-  
extractor.  
As water fills the washer-extractor, one or more of the  
indicator lights located to the left of the keyboard will  
come on and stay on until the required water level is  
reached. LED dots located in the upper left corner of  
the last three digits on the right of the display will  
illuminate to indicate the water level(s) reached:

Operation  
The display will read “W1-cc,” “W2-cc,” or “W3-cc”  
for Wash 1, Wash 2, or Wash 3 action during the  
shakeout portion of the stop routine until the final  
10 seconds. (The “cc” here stands for the current cycle  
number and will be represented by numbers in the  
actual display.) During the final seconds, the display  
reads “STOPcc.” The display will then read

could result in serious injury.  
SW012  
“DONEcc.” At that point, the door can be opened. If  
rotation is sensed, control does not allow door to open.  
The operator can select the agitation which will be in  
effect for the STOP routine “shakeout.” To minimize  
cycle time, if rotation has stopped, the control  
shakeout time is brief. This will help prevent tangling  
of the load and provide maximum control. Three  
agitations are available for the STOP routine. They are  
as follows:  
In stop routine, the coast time ensures a minimum time  
for coast. After the minimum, the control determines if  
rotation sensor is working, then a short shake-out  
routine begins when cylinder rotation stops. At the end  
of shake-out routine, “STOPxx” displays briefly, then  
displays “donExx”, if there is no rotation. If rotation is  
sensed, control does NOT show “donE” and prevents  
door from being opened. When no rotation is sensed,  
door can be opened.

To select the agitation in the stop routine, program a  
Wash 1, 2, or 3 step for 1 second. The washer-  
extractor will begin refilling to the most recent water  
level if the time is more than 1 second. If the most  
recent wash type was Wash 4, 6, or 7, the WE-6 will  
default to no agitation (Wash 3) during the stop  
routine.  
NOTE: If the desired action is not programmed in  
the final cycle step, the control will default to the  
most recent action in the cycle. If the cycle stops  
prematurely, the most recent action at the time the  
cycle is interrupted will be in effect during the stop  
routine.

Operation  
Certain error conditions are considered to be non-  
recoverable:  
Error Recovery Routine  
When the control detects an error, it will stop running  
the current step and display a message to indicate what  
type of error was found:  
If the door opens during a cycle, the control will  
display “DOOR.” The operator must close the  
door.  
“FILL” indicates that the washer-extractor did  
Then, after the control has detected that the door  
is closed, it will automatically abort the cycle and  
go to the normal stop routine.  
not fill within the allotted time.  
“EMTY” indicates that the washer-extractor did  
not drain in the allotted time.  
“OVERHT” will be displayed when the control  
detects an open or shorted temperature input  
circuit or temperatures are outside of the washer-  
extractor’s allowable limits. Contact a service  
technician.  
“TEMP” indicates that the temperature sensor  
has recognized a temperature above the  
programmed value.  
“MEMR” indicates that the control has detected a  
problem with the cycle information. The cycle  
must be edited.  
WATER” indicates that the WE-6 control  
senses low, medium, or high water level at the  
end of the stop routine.  
“DRTEMP” indicates that the WE-6 has detected  
water temperature over 160°F in a “drain to  
reuse” step. Instead of draining to a tank, the  
control gives this error message. The cycle must  
be edited so the temperature is below 160°F upon  
entering a reuse drain step (“Da” or “Db”).  
All outputs remain off while the message  
displays, and the door cannot be unlocked.  
NOTE: The WE-6 control will not allow the door to  
be opened while there is water in the washer-  
extractor.  
Each of these errors is considered to be recoverable.  
The operator has two minutes to respond to the error  
condition (except in the case of “WATER”). During  
this time, the control will turn the signal (buzzer) relay  
on and off at the rate of one second on and one second  
off to alert the operator to the error condition. The  
washer-extractor may be restarted by pressing the Start  
keypad. Pressing the Start keypad will restart the cycle  
step for the originally programmed time period.  
WATER” will remain displayed until the error is  
corrected. The cycle may be aborted by pressing the  
Stop keypad. After aborting the cycle, the control will  
go to the normal stop routine. If the operator does not  
respond to the error condition within the allocated two  
minutes, the control will automatically abort the cycle.  
NOTE: The “TEMP” alarm can be recovered only  
after the temperature falls below the alarm level.

Monthly  
bolts and slide motor along motor plate to  
change belt span length. The belt tension on  
UW35 – UW125 models should be between  
70 and 90 pounds ( 5 pounds). The belt  
tension on the UW150 should be between  
130 and 150 pounds ( 5 pounds). (Set initial  
tension toward the high end of this range.)  
The UW150 uses a swing mount motor with  
an adjustable spring used for tensioning.  
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 right side of  
the machine, as viewed from the front of the  
washer-extractor.)  
Deflection. Refer to Figure 12. Loosen motor  
mounting bolts and slide motor along motor  
plate to change belt span length. Belt tension  
measurements should be taken as close to the  
center of the belt span as possible. For every  
inch of span length, the belt should deflect  
1/64 inch (0.40 mm). Thus, a belt with span  
length of 50 inches should deflect 50/64 inch  
(19.84 mm). An initial (run-in) force of  
5.25 pounds should be used to set the belt  
tension. An operating (normal) force of  
3.5 pounds should be used after the washer-  
extractor has been operated for a few hours.

Maintenance  
Do not leave sanitizers or sterilizing solutions on  
stainless steel equipment for prolonged periods  
of time.  
Care of Stainless Steel  
Remove dirt and grease with detergent and water.  
Thoroughly rinse and dry after washing.  
When an external chemical supply is used,  
ensure no siphoning of chemicals occurs when  
the washer-extractor is not in use. Highly  
Avoid contact with dissimilar metals to prevent  
galvanic corrosion when salty or acidic solutions  
are present.  
concentrated chemicals can cause severe damage  
to stainless steel and other components with the  
machine. Damage of this kind is not covered by  
the manufacturer’s warranty. Locate the pump  
below the washer-extractor’s injection point to  
prevent siphoning of chemicals into the machine.  
Do not allow salty or acidic solutions to  
evaporate and dry on stainless steel. Wipe clean  
of any residues.  
Rub in the direction of the polish lines or “grain”  
of the stainless steel to avoid scratch marks when  
using abrasive cleaners. Use stainless steel wool  
or soft, non-metal bristle brushes. Do not use  
ordinary steel wool or steel brushes.  
If the stainless steel appears to be rusting the  
source of the rust may actually be an iron or steel  
part not made of stainless steel, such as a nail or  
screw. Tip: Paint all carbon steel parts with a  
heavy protective coating. Stainless steel fasteners  
should be used whenever possible.  
Remove discoloration or heat tint from  
overheating by scouring with a powder or by  
employing special chemical solutions.
