discarded, remove the door to the washing
compartment.
8. Do not reach into the washer if the wash drum is
moving.
9. Do not install or store the washer where it will be
exposed to water and/or weather.
10. Do not tamper with the controls.
11. Do not repair or replace any part of the washer or
attempt any servicing unless specifically
recommended in the user-maintenance
instructions or in published user-repair
instructions that the user understands and has the
skills to carry out.
12. To reduce the risk of an electrical shock or fire,
DO NOT use an extension cord or an adapter to

W023
1. Read all instructions before using the washer.
2. Refer to the GROUNDING INSTRUCTIONS in
the INSTALLATION manual (supplied with your
washer) 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, drycleaning solvents or other flammable or
explosive substances. 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
washer, 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.

14. Never wash machine parts or automotive parts in
the machine. This could result in serious damage
to the basket.
15. ALWAYS disconnect the washer from its
electrical supply before attempting any service.
16. Install the washer according to the
INSTALLATION INSTRUCTIONS. All
connections for water, drain, electrical power and
grounding must comply with local codes and,
when required, be made by licensed personnel.
17. To reduce the risk of fire, textiles which have
traces of any flammable substances such as
vegetable oil, cooking oil, machine oil,
flammable chemicals, thinner, etc. or anything
containing wax or chemicals such as in mops or
cleaning cloths, must not be put into the washer.
These flammable substances may cause the
fabric to ignite.
18. Do not use fabric softeners or products to
eliminate static unless recommended by the

Theory of Operation
Starting the Machine
Drain
The door lock will not allow a cycle to be started until
the door has been closed.
Cabinet Hardmount washer-extractors use a normally
open gravity-type drain system. No pump is used.
When the drain valve opens, the perforated basket
allows water to drain from it.
Fill
The operator selects a cycle and starts the machine.
Water enters the machine through water valves that are
controlled by the microcomputer. As water fills the
basket, a column of air is trapped in a pressure bulb
and hose. The air pressure continues to increase as the
basket fills with water. When the desired water level is
reached, the water level switch triggers the
microcomputer and the water valves turn off.
A vacuum breaker installed in the inlet plumbing
prevents the backflow of water.
In the event of a power failure, the drain valve will
open automatically and the machine will drain.
Extract
A final high-speed extract step removes water from the
load, which maximizes drying efficiency.
The door lock system will not allow the door to be
opened until the cycle has finished.
Supply
The operator can either connect external liquid
supplies to the machine or fill the supply dispenser
with liquid or dry supplies. The supply dispenser's
nozzles flush the compartments with water at the
appropriate times throughout a cycle.
Wash
The basket includes ribs that lift the laundry from the
wash water. The laundry then tumbles back into the
bath.
In 2-speed and variable-speed models, 1 dual-speed
motor drives the basket's shaft with a V-belt. In 3speed models, 2 motors drive the basket's cylinder
with a V-belt.
18-60 pound capacity models use 2 bearings that are
held in place by a single cast-iron trunnion that is
bolted to the frame. 80 and 125-pound capacity
models use 2 flange-type bearing that are bolted to the
frame.

Troubleshooting
15. Overload Relay Tripping Repeatedly
Repeated overload tripping may result from a failed sinpac switch. Symptoms of a failed
sinpac switch may include motor humming without rotation during spin or high current during
running speed.
The overload relay is tripping
repeatedly.
Yes
Disconnect the power from the machine.
Remove the SS2 and SS3 wires from the
sinpac switch. Connect the two wires
together using a jumper wire. Re-connect
power to the machine. Make sure that the
machine's basket is fully loaded. Manually
engage the spin contactor. CAUTION: Do
not run the motor for more than 5 to 7
seconds. Does the motor spin?
Is the input voltage to
the machine between
208 and 240 Volts?
Consult the power
company in getting the
power turned down or
consult an electrician
about installing a
buckboost transformer.
No
Inspect the spin
Yes
contactor. While manually
pressing the contactor, do
all of the contacts
engage?
Yes
No
No
One or more of the start
capacitors may have failed or
the wiring to the start capacitors
may be incorrect.
Perform a capacitance test on
the start capacitors and replace
them as needed.
Inspect the start capacitor wiring
and repair and/or replace the
wiring as needed.
Replace the contactor.
Perform current measurements of the incoming power
leads as follows (measure both L1 and L2 at the same
time). Manually engage the spin contactor for 5 to 7
seconds to get the motor spinning. The current should
range from about 15 to 60 Amps, depending on the
machine's size and load conditions. Quickly remove the
connection between SS2 and SS3 while the motor is
still spinning at a high rate and then re-engage the spin
contactor. The motor should continue to spin at a high
speed and the current should drop down to between 3
and 8 Amps, depending on the machine's size and load
conditions. Does the motor maintain high speed and/or
does the current drop after disconnecting SS2 and
SS3?
Yes
No
Check the capacitor values and
the spin circuit wiring. Replace
the capacitors as needed.
Repair and/or replace the wiring
as needed.
CHM430S
Replace the sinpac switch.

16. Compartment 2 of Supply Dispenser Not Flushing Completely
Compartment 2 of the
supply dispenser is not
flushing completely.
Install a hose clamp onto one of the hoses connecting to the
top of the vacuum breaker and tighten the hose clamp slightly.
Refer to the Vacuum Breaker Illustration.
Is there low
water pressure
(i.e., less than 30
psi) to the supply
dispenser?
NOTE: If the water pressure is corrected to factory
specifications, the hose clamp may have to be removed.
Yes
As an alternative, cut a 3/4-inch by 1/2 inch notch out of the
bottom of the water deflector in compartment 2 of the supply
dispenser. Refer to the Dispenser Illustration
.
NOTE: If the water pressure is corrected to factory
specifications, the notch must be plugged to avoid
splashing.

Troubleshooting
17. Troubleshooting and Cleaning the Coin Drop
When coins are placed into the coin slot, do they fall into the coin vault and does the
coin drop sensor register that coins have been entered? Refer to Figure 1 for the path
that coins follow when the drop is working properly.
No
1. Disconnect electrical power to the machine and the coin drop.
2. Remove the coin drop from the machine.
Refer to the wiring
diagram supplied
with the machine
for connection
information.
No
Is proper
electrical
power
supplied to
the coin
drop?
3. If lint is preventing coins from rolling through the coin drop, blow compressed air
through the coin entry and along the side of the coin drop. Refer to Figure 2.
4. Insert a coin into the coin drop. If the coin does not fall through the drop, continue
to step 5.
5. Remove the cotter pin from the top of the drop. Refer to Figure 2. Save the pin for
reinstallation when the cleaning of the coin drop is complete.
Yes
Refer to the
installation manual
supplied with the
machine for
instructions on
leveling the
machine.
6. Move the metal clip closer to the sensor so that it comes off of the frame. Refer to
Figure 2.
No
Is the
machine
level?
7. Remove the coin return from the coin drop frame. Refer to Figure 3.
8. Check the path in the coin drop for lint and residue. If lint or light residue is present,
use a cotton swab to remove it. If heavy residue is present, it may be necessary to
first scrape off the excessive residue and then to use a cotton swab dipped in water
or isopropyl alcohol to remove the remainder of the residue. Refer to Figure 4.
Yes
Is the coin
drop clean?
No
9. Check the return pendulum to verify it swings freely. If the pendulum does not
swing freely, spray the pendulum pivot point with Teflon-based lubricant and move
the pendulum back and forth 3 times. An additional application of Teflon-based
lubricant may be necessary to ensure the pendulum swings freely. Refer to Figure 5.
10. Check the coin drop sensor for dust or dirt on the eyes. Wipe the eyes with a dry
cotton swab. Refer to Figure 6. IMPORTANT: Do not use isopropyl alcohol to clean
the electronic sensor or eyes.
11. Reinstall the coin return onto the coin drop frame.
12. Reinstall the metal clip and slide toward the coin insert slot. All cotter pin holes
must line up.
13. Reinstall the cotter pin.
14. Place the coin drop on a level surface to verify that coins follow the correct path to
the coin drop. It may be necessary to lift the coin drop to allow the coin to follow
through the sensor.
15. Reinstall the coin drop into the machine.
16. Reconnect electrical power to the machine and coin drop.
17. Insert a coin into the coin drop to verify that the coin drop is operating properly.
If the coin drop does not operate properly after the above steps have been
completed, corrosion of the metal or vandalized components within the coin drop may
be preventing it from functioning properly. Replace the coin drop.
