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.

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. Replace worn power cords and/or loose plugs.
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.
NOTE: The WARNINGS and IMPORTANT
SAFETY INSTRUCTIONS appearing in this
manual are not meant to cover all possible
conditions and situations that may occur. Common
sense, caution and care must be exercised when
installing, maintaining, or operating the washer.
Any problems or conditions not understood should be
reported to the dealer, distributor, service agent or the
manufacturer.

Operator Safety
To ensure the safety of machine operators, the
following maintenance checks must be performed
daily:
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.
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.
b. Close the door without locking it and attempt
to start the machine. The machine 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.
3. Do not attempt to operate the machine if any of
the following conditions are present:
a. The door does not remain securely locked
during the entire cycle.
b. Excessively high water level is evident.
c. Machine is not connected to a properly
grounded circuit.
Do not bypass any safety devices in the machine.
Safe Operating Environment
Safe operation requires an appropriate operating
environment for both the operator and the machine. If
questions regarding safety arise, contact the
manufacturer immediately.
Environmental Conditions
•Ambient Temperature. Water in the machine will
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.
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.
•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.
If the relative humidity is below 30%, belts and
rubber hoses may eventually develop dry rot.
This condition can result in hose leaks, which
may cause safety hazards external to the machine
in conjunction with adjacent electrical
equipment.
•Ventilation. The need for make-up air openings
for such laundry room accessories as dryers,
ironers, water heaters, etc., must be evaluated
periodically. Louvers, screens, or other
separating devices may reduce the available air
opening significantly.
•Radio Frequency Emissions. A filter is available
for machines in installations where floor space is
shared with equipment sensitive to radio
frequency emissions.
•Elevation. If the machine is to be operated at
elevations of over 3280 feet (1000 m) above sea
level, pay special attention to water levels and
electronic settings (particularly temperature) or
desired results may not be achieved.
•Chemicals. Keep stainless steel surfaces free of
chemical residues.
NEVER insert hands or objects into
basket until it has completely stopped.
Doing so could result in serious injury.
SW012
WARNING
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.
