Safety Information
Important Safety Instructions
WARNING
To reduce the risk of fire, electric shock, serious injury or death to persons when using your
washer, follow these basic precautions:
W023
1. Read all instructions before using the washerextractor.
2. Refer to the GROUNDING INSTRUCTIONS in
the INSTALLATION manual (supplied with your
washer-extractor) for the proper grounding of the
washer-extractor.
3. Do not wash textiles that have been previously
cleaned in, washed in, soaked in or spotted with
gasoline, dry-cleaning 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-extractor, 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 a washerextractor. Close supervision of children is
necessary when the washer-extractor is used near
children.
7. Before the washer-extractor is removed from
service or discarded, remove the door to the
washing compartment.
8. Do not reach into the washer-extractor if the wash
basket is moving.
9. Do not install or store the washer-extractor where
it will be exposed to water and/or weather.
10. Do not tamper with the washer-extractor’s
controls.
4

Section 3
Theory of Operation
Starting the Machine
Drain
The door lock will not allow a cycle to be started until
the door has been closed.
Standard models include a normally-open gravity-type
drain system. When the drain valve opens, the
perforated basket allows water to drain from it. A
pump drain is available as an option on the smallercapacity models.
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 or a
shell overflow and air gap prevents the backflow of
water.
Supply
In the event of a power failure, the drain valve will
open automatically and the machine will drain.
Standard models include a single drain valve. On dual
drain models, which are available as an option, the two
drain valves open and close together.
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.
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.
A variable-speed motor drives the basket's shaft with a
V-belt.
The bearing housing is mounted to the tub support's
brackets. The tub support is mounted onto the frame
with shock absorbers so it can move independently
from the frame.

5. Water Runs Continuously into the Washer-Extractor
NOTE: This information applies to the three main fill valves as well as the three supply valves. The first task in this
process is to determine which valve is staying on. This may be done by individually shutting off the water supply to
each valve. Find the location where the water is flushing into the machine and follow the hose back to the solenoid.
Once the valve has been identified, proceed as follows:
Turn the main
power to the
machine off.
Does the water
shut off?
Clean the valve or
install a repair kit inside
the valve if available. If
a repair kit isn’t
available, replace the
entire valve.
NO
YES
Turn the power
to the machine on.
Is there voltage (220 Volts)
between the two wires of the
solenoid on the water valve
that is staying on?
NO
1
For example, if the 1-5 (hot fill
on X18-75) is staying on, is
there voltage (220 Volts)
between the output (red) and
common (blue) wires of the
solenoid?
YES
Repair or replace the
main board (water)
harness as needed.
Is the
main board
(water) harness
connected correctly
as shown on the wiring
schematic and is it intact?
NO
Check the microprocessor
display to make sure that
the microprocessor isn’t
calling for the water
valve to turn on when it
shouldn’t be. If it is, turn
off the power to the machine
for at least 20 seconds and
then turn the power back
on. Make sure that the
display reads “CYCLE 00.”
2
YES
Note: Make sure there are
no wires loose, shorted
or disconnected
from the main
board (water)
harness.
If the microprocessor is
still calling for the water
valve to turn on when it
shouldn’t be, assuming
that all checks were done
correctly, replace the
main board or contact
Alliance Laundry Systems’
customer service
department to verify that
all checks have been done
correctly.
