 To prevent injury to the user or property damage, the following instructions must be followed.
 Incorrect operation due to ignoring instruction will cause harm or damage.
 Before servicing unit, be sure to read this service manual at first.
1.2 Warning
 Before use, the washer must be properly
installed as described in user manual.
 ALWAYS follow the fabric care instructions
supplied by the garment manufacturer.
 Do not wash articles that have been
previously cleaned in, washed in, soaked in,
or spotted with gasoline, dry-cleaning
solvents, other flammable or explosive
substances as they give off vapors that
could ignite or explode.
 Do not reach into the appliance if the basket
is moving.
 Do not install or store this appliance where it
will be exposed to the weather or freezing
temperatures.
 Do not tamper with the controls.
 Do not add gasoline, dry-cleaning solvents,
or other flammable or explosive substances
to the wash water. These substances give

 HYDROGEN GAS IS EXPLOSIVE. If the
hot water system has not been used for 2
weeks or more, before using a washer or
combination washer-dryer, turn on all hot
water faucets and let the water flow from

flame during this time.
 Keep the area underneath and around your
appliances free of combustible materials
(lint, paper, rags, etc.), gasoline, chemicals
and other flammable vapors and liquids.

RVs, aircraft, etc.
 Turn off the water faucets and unplug the
washer if the machine is to be left for an

 Always check the inside of the washer for
foreign objects before loading laundry. Keep
the lid closed when not in use.
 Plug the power cord into an AC 120V/60Hz
wall socket rated at 15amps or higher. Use
the socket for this washer only.
 Do not use an extension cord.

appliance, using a power strip, or
extending the power cord may result in
electric shock or fire.
- Do not use an electric transformer. It
may result in electric shock or fire.
