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
Read all instructions before using the
appliance.
Use this appliance only for its intended
purpose as described in this owner’s
Manual.
Before use, the washer must be properly
installed as described in this manual.
ALWAYS follow the fabric care instructions
supplied by the garment manufacturer.
Do not wash or dry 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 allow children to play on or in the
appliance.
Close supervision of children is necessary
when the appliance is used near children.
Before the appliance is removed from
service or discarded, remove the lid of the
washing or drying compartment.
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 repair or replace any part of the
appliance or attempt any servicing unless it
is specifically recommended in the user-
maintenance instructions or in published
user-repair instructions that you understand
and have the skills to carry out.
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

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

Installation Steps
These instructions should be retained for future reference.

-------------------------------------------------------------------------------------------------------------------------------------------------------
－ 13 －
Follow the followings STEP by STEP to ensure a successful installation.
STEP 1: Select a location
Before you install the washer, make sure the location:
- Has a hard, level surface without carpeting or flooring that may obstruct ventilation.
- Is away from direct sunlight.
- Has adequate ventilation.
- Is not exposed to freezing temperatures (temperature under 32°F or 0 °C.
- Is away from heat sources such as oil or gas.
- Has enough space so that the washer doesn’t rest on its power cord.
STEP 2: Connect the water hose
The water supply hoses are not supplied with your washer and must be purchased separately. Before installing
the water supply hoses, make sure there are rubber gaskets inside the fittings at both ends of each new water
hose. Installing the water supply hoses without rubber gaskets can cause water leakage. When you initially install
the washer, be sure to use new hoses. Failing to do so may result in a water leakage or overflow and may damage
your property. Do not connect multiple water supply hoses together to increase the length of the supply hose.
Hoses connected this way can leak and the leakage can cause electrical shock. If a hose is too short, replace the
hose with a longer, high pressure hose.
1. Connect the ends of the water supply hoses to the HOT and COLD faucets.
2. Tighten the fittings by hand until they are snug, and then tighten them an additional two-thirds of a turn with
a wrench.
When you fasten the fittings, do not fasten them too tightly or apply tape or sealant to the faucets or water supply
intakes. This can damage the fittings. After you have connected the water supply hoses to the faucets, ensure
that they are connected correctly by pulling the water supply hoses downwards.
3. Place the unconnected ends of the hoses into a bucket and open the faucets connected to the two water supply
hoses for 10 or 15 seconds to remove any foreign substances from the hoses. Close the faucets before continuing.
4. Connect the ends of the water supply hoses to the water supply intake connections at the back of the washer.
The water supply hose connected to the HOT faucet must be connected to the hot water supply intake and the

Service manual for Washing Machine
-------------------------------------------------------------------------------------------------------------------------------------------------------
－ 14 －
water hose connected to the COLD faucet must be connected to the cold water supply intake.
5. Tighten the fittings by hand until they are snug, and then tighten them an additional two-thirds of a turn with
a wrench. Confirm that the water supply hoses are not twisted or bent. If the hoses are twisted or bent, the hoses
can leak and cause electric shock due to the water leakage.
To ensure the correct water usage, connect both the HOT and COLD water faucets. If either or both are not
connected, an error code can occur. If you do not want to use the HOT water supply hose, insert the water intake
cap into the HOT water supply intake hole. In this case, you must select the Tap Cold option for the water
temperature.
6. Turn on the HOT and COLD water supplies and check all the water supply intake connections and the faucets
for water leaks.
STEP 3: Connect the drain hose
1. Put the Drain Hose out of the Clamp.
2. Position the other end of the drain hose.
It can be positioned in three ways.
A. Over the edge of wash basin
Secure the guide to the side of the basin wall with a hook or to the tap with a piece of string to prevent the
drain hose from moving.

Service manual for Washing Machine
-------------------------------------------------------------------------------------------------------------------------------------------------------
－ 15 －
B. In a standpipe
The standpipe must be no shorter than 39 in.(99cm) and no longer than 96 in. (245cm).
C. In a laundry tub
The laundry tub must be no shorter than 39 in. (99cm) and no higher than 96 in. (245cm).
Make sure that the connection between the drain hose and the wash basin, or standpipe, or laundry tub is not
airtight.
STEP 4: Leveling your washer
Determine if the washer is level by checking the position of the tub or using a level.
1. Slide the washer into position.
2. Open the lid of the washer, and pour the water into the tub to the leveling circle. If the washer is level ,the
water will touch the leveling circle all the way around. If the washer is not level, the water will only touch part
of the leveling circle.
2. If the washer is not level, carefully tilt your washer just enough to adjust the leveling one the bottom front
of your washer. Extend the feet only as much as is necessary. If the feet are extended too much, your washer
may vibrate.
DO NOT use your washing machine without leveling. It may result in malfunction caused by the production
of excess vibration and noise. Use the leveling feet only when you level the washing machine. If you raise the

Service manual for Washing Machine
-------------------------------------------------------------------------------------------------------------------------------------------------------
－ 16 －
leveling feet unnecessarily, it may cause abnormal vibration of the washing machine.
STEP 5: Powering your washer
Plug the power cord into a 3-prong, well grounded 120Volt 60Hz approved electrical outlet protected by a 15-
amp fuse or comparable circuit breaker.
Your washer is grounded through the third prong of the power cord when plugged into a 3-prong grounded
electrical outlet.
STEP 6: Running a test cycle
Run a test cycle as following to check if your washer is properly installed.
1. Load about 6 pounds of laundry into the tub.
2. Select the Cycles to turn on your washer.
3. Select the cycle by turning the.
4. Press the button to start the test cycle.
5. The washer should not rock or vibrate excessively when water is supplied or when washing or spinning, and
should drain well during the spin cycle.
If water leaks while water is being supplied or drained, check the water connections. Refer to the “Connect
the water hose”and “Connect the drain hose”section for instructions.
If the washer rocks and vibrates excessively, level your washer again. Refer to the“Leveling your washer”
section for instructions.
