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.
DANGER
WARNING indicates the presence of a
hazard that can cause severe personal
injury, death, or substantial property
damage if the warning is ignored.
WARNING
CAUTION indicates the presence of a
hazard that will or can cause minor
personal injury or property damage if the
caution is ignored.
CAUTION
To reduce the risk of fire, electric shock,
serious injury or death to persons when
using your washer, follow these basic
precautions: W023

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 electric shock or fire, DO
NOT use an extension cord or an adapter to
connect the washer to the electrical power source.
13. Use washer only for its intended purpose,
washing textiles.
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 electrical
supply before attempting any service. Disconnect
the power cord by grasping the plug, not the cord.
16. Install the washer according to the
INSTALLATION INSTRUCTIONS. All
connections for water, drain, electrical power and
grounding must comply with local codes and be
made by licensed personnel when required.
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 and
cleaning cloths, must not be put into the washer.
These flammable substances may cause the
fabric to catch on fire by itself.
18. Do not use fabric softeners or products to
eliminate static unless recommended by the
manufacturer of the fabric softener or product.
19. Keep washer in good condition. Bumping or
dropping the washer can damage safety features.
If this occurs, have washer checked by a qualified
service person.
20. If supply cord is damaged, it must be replaced by
a special cord or assembly available from the
manufacturer or its service agent.
21. Be sure water connections have a shut-off valve
and that fill hose connections are tight. CLOSE
the shut-off valves at the end of each wash day.
22. Loading door MUST BE CLOSED any time the
washer is to fill, tumble or spin. DO NOT bypass
the loading door switch by permitting the washer
to operate with the loading door open.
23. Always read and follow manufacturer’s
instructions on packages of laundry and cleaning
aids. Heed all warnings or precautions. To reduce
the risk of poisoning or chemical burns, keep
them out of the reach of children at all times
(preferably in a locked cabinet).
24. Always follow the fabric care instructions
supplied by the textile manufacturer.
25. Never operate the washer with any guards and/or
panels removed.
26. DO NOT operate the washer with missing or
broken parts.
27. DO NOT bypass any safety devices.
28. Failure to install, maintain, and/or operate this
washer according to the manufacturer’s
instructions may result in conditions which can
produce bodily injury and/or property damage.

Introduction
Introduction
The “B” electronic control is composed of the
electronic control unit and the control fuse board with
wiring harness. Only an authorized person should look
inside the machine. First TURN OFF POWER, open
lid and remove any cover present. The components are
described below.
Electronic Control Unit
This portion of the control contains the “intelligence” –
the micro-controller and the miscellaneous components
on the printed circuit (PC) board. The board has a
metal cover, which MUST be in place at all times
during machine operation. Operation of the machine
without this cover installed will void the warranty.
The control unit monitors and responds to input, gives
information about the status of the washer and
monitors and responds to inputs from the user
interface (keypad). The control provides signals to the
control output unit, which in turn operates the
components that control the machine functions. This is
located behind the machine control panel.
Control Output Fuse Board
This portion of the control contains the power supply
for the control unit, and also the switching devices
which power the components in the machine, all of
which are on the output PC board. The switching
devices are controlled by the control unit, and are solid
state.
Harnessing
Wiring harnesses are modular – harnesses common to
various configurations are similar, while those specific
to a certain configuration can be added. There are
harnesses for inputs to the control unit, for outputs
from the control power/output unit to the machine
components, and for the main incoming power to the
control power/output unit.
Communications
The control will accept communications with a Card
Reader in order to perform vending transactions when
a card is inserted to pay for cycles. The Card Reader
can also allow the owner to program and collect audit
information.
For detailed information on the Card Reader
Communications, refer to the third party Card Reader
manufacturer.
