• Read all instructions before using the washer.
• Do not wash articles that have been previously
cleaned in, washed in, soaked in, or spotted with
gasoline, dry cleaning solvents, or other
flammable or explosive substances, as they give
off vapors that could ignite or explode.
• 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.
• Under certain conditions, hydrogen gas may be
produced in a hot water system that has not been
used for 2 weeks or more. HYDROGEN GAS IS
EXPLOSIVE. If the hot water system has not been
used for such a period, before using the washing
machine, turn on all hot water faucets and let the
water flow from each for several minutes. This will
release any accumulated hydrogen gas. As the gas
is flammable, do not smoke or use an open flame
during this time.
• Do not allow children to play on or in the washer.
Close supervision of children is necessary when
the washer is used near children.
• Before the washer is removed from service or
discarded, remove the door to prevent children
from hiding inside.
• Do not install or store the washer where it will be
exposed to the weather.
• Do not tamper with controls.
• Do not repair or replace any part of the washer or
attempt any servicing unless specifically
recommended in the user-maintenance
instructions or published user-repair instructions
that you understand and have the skills to carry
out.
• See Installation Instructions for grounding
requirements.
• ALWAYS follow the fabric care instructions
supplied by the garment manufacturer.
• Do not place items exposed to cooking oil in your
washer. Items contaminated with cooking oils may
contribute to a chemical reaction that could cause
a load to catch fire.
• Do not use fabric softeners or products to
eliminate static unless recommended by the
manufacturer of the fabric softener or product.
WARNING
To reduce the risk of fire, electric shock, or injury to persons when using the washer, follow basic
precautions, including the following:

This appliance must be grounded. In the event of malfunction or breakdown, grounding will reduce the risk
of electric shock by providing a path of least resistance for electric current. This appliance is equipped with
a cord having an equipment-grounding conductor and grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
• Do not use an adapter or extension cord.
• Do not remove ground prong.
• If you don’t have the proper outlet, consult an electrician.
GROUNDING INSTRUCTIONS
WARNING
Improper connection of the equipment-grounding conductor can result in risk of electric shock.
Check with a qualified electrician or serviceman if you are in doubt as to whether the appliance is
properly grounded. Do not modify the plug provided with the appliance - if it does not fit the outlet,
have a proper outlet installed by a qualified electrician.
