WARNING!
• 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

Level floor
Allowable slope under entire washer is 1˚.
Power outlet
Must be within 60 inches (1.5 m) of either
side of the washer. Do not overload the
outlet with more than one appliance.
Time-delay fuse or circuit breaker is
recommended.
It is the personal responsibility
and obligation of the customer
to have a proper outlet installed
by a qualified electrician.
Minimum installation spacing
• Additional spacing of 1 in. (2.5 cm) on all
sides of the washer is recommended to
reduce noise transfer.
• Most installations require a minimum 4 in.
(10 cm) clearance behind the washer.
• Companion appliance spacing should also
be considered.
Installation place requirement
Positioning
• To minimize noise and vibration, the washer MUST be installed on a solidly
constructed floor.
• Carpeting and soft tile surfaces are not recommended.
• Never install the washer on a platform or weakly supported structure.
A firm, solid floor is even more critical to a front-loading washer than to a top-loader.
If your floor is wood and/or frame construction, you may need to reinforce it. Frontloaders use substantially faster spin speeds than top-loaders, causing greater
vibration. If the floor is not solid, your washer will vibrate. You will hear and feel the
vibration throughout your house.

1. Fabric Care Labels
Look for a care label on your clothes. This will tell you about the fabric content of your
garment and how it should be washed.
2. Sorting
To get the best results, sort clothes into loads that can be washed with the same wash cycle.
Different fabrics need to be washed in different ways.
Always sort dark colors from pale colors and whites. Wash separately as dye and lint transfer
can occur causing discoloration of white clothing. If possible, do not wash heavily soiled
items with lightly soiled ones.
Soil (Heavy, Normal, Light) Separate clothes according to amount of soil.
Color (White, Lights, Darks) Separate white fabrics from colored fabrics.
Lint (Lint Producers, Collectors) Wash lint producers and lint collectors
separately.
3. Check before loading
WARNING - To reduce the risk of fire, electric shock, or injury to persons, read the
IMPORTANT SAFETY INSTRUCTIONS before operating this appliance.
Combine large and small items in a load. Load large items first. Large items should not be more
than half the total wash load.
Do not wash single items. This may cause an out-of-balance load. Add one or two similar items.
• Check all pockets to make sure
that they are empty. Things such
as nails, hair clip, matches, pens,
coins and keys can damage both
your washer and your clothes.
• Close zippers, hooks, and strings
to make sure that these items don’t
snag on other clothes.
• Pre-treat dirt and stains by
brushing a little detergent dissolved
in water onto stains like collars and
cuffs to help shift dirt.
Do not wash or spin water-proof clothes.
!
Before the first washing
Select the Normal cycle, add about 1/2 the recommended amount of detergent in the dispenser, and allow
the unit to wash without clothing. This will remove any residue from the drum that may remain after
manufacturing.

• High efficiency (HE) detergent is
recommended for this washer.
• Use the manufacturer's recommended
amount.
• If high efficiency (HE) detergent is not
available, a reduced amount of regular
detergent may be used.
• Because reducing the amount of
detergent may reduce cleaning, it is
important to pretreat stains, sort carefully
by color and soil level, and avoid
overloading.
• Detergent usage may need to be adjusted
for water temperature, water hardness,
size and soil level of the load. For best
results, avoid using too much detergent.
• Detergent is dispensed at the beginning of
the cycle.
4. Detergent usage
