When performing troubleshooting and part replacement during servicing, note the
following safety
precautions:

1.1 Safety Precautions

1.1.1 Use Genuine Parts
The components of the washing machine have safety features such as non-combustibility
and voltage with standing. Therefore, always use the same part as suggested by the maker.
In particular be sure
to use only designated parts in case of major safety parts identified by the marker.

1.1.2 Grounding
Connect the grounding wire to the shell plate ,and bury it under at least 25cm of earth:
alternatively, connect the ground wire to the appropriate pin on a properly grounded
power receptacle. Never connect the wire to a telephone line, lightning rod, or gas pipe.

1.2 Servicing Precautions

1.2.1Observe Warnings
Be sure to follow special warning and precautions that are described on part labels and in
the owner'
manual.

1.2.2 Parts Assembly and Wiring
Be sure to use insulation material(such as tube and tape).And be sure to restore all parts
and wires to their original position. Take special care to avoid contact with sharp edges.

1.2.3 Perform Safety Checks after Servicing
After servicing, check to see that the screws, parts, and wiring are restored to their
original positions, and check the insulation between the external metals and the socket
plug. In addition, place the washing machine in a level position (less than1 degree)to
prevent vibration and noise during operations.

1.2.4 Insulation Checks
Pull out the plug from the power receptacle, pour water into the spin tub, and then set
the timer.
Check to see that the resistance insulation between the terminals of the plug and the
externally
exposed metal is greater than 1M .

Note :When it is impossible to insulation check with a 500V insulation resistance
tester, use other testers for inspection.

which is not

unnecessary to power on . Do not hold the plug by a wet hand.

Failing to unplug may cause an electric shock.

USE REPAIR PARTS

Use the specified repair parts when repairing the product.
Otherwise , amalfunction or a defect may occur.
Also , a short circuit , ignition or other danger to the
customer may occur.

1 PRECAUTION

5

WARNING

CHECK INSULATION

RESISTANCE

After repair, measure insulation resistance between the
charging part(power cord plug) and the non-charging
metallic part (ground) with an insulation resistance meter
(500V).The resistance shall be 10M or more.
Failing to check the insulation resistance may cause a short
circuit, electric shock or other diseases to the customer.

DO NOT MODIF

Do not modify the product.
An electric shock or ignition may occur.

DO NOT MODIFY

Only a repair technician can disassemble and repair.
An electric shock, ignition or malfunction may cause injury.

USE EXCLUSIVE

SOCKET

Use an exclusive 110 VAC/15 A socket for the washing
machine.
Use an exclusive 220VAC/17A socket for the washing
machine.
Otherwise , an electric shock or ignition may cause. Sharing
the same socket with other instrument causes heating of a
branch socket and result in a fire.

CONNECT

GROUNDING WIRE

Connect the grounding wire.
Failing to do so may cause an electric shock when a short
circuit occurs.
Consult an electric work shop or a sales shop.

DO NOT USE WET

PLACE

Do not install in a bath room or a place exposed to wind or
rain.
An electric shock or a short circuit may cause a fire.

DO NOT SPLASH

WATER

Do not pour or immerse electrical parts into water or liquid
solution.
An electric shock or ignition may occur.

CAREFULLY

Ask an electric work shop to install the product.
Install the product securely and safely according to the
electrical equipment technical standard and the wiring
standard.
Incorrect work causes an electric shock and a fire.

DO NOT PULL

Do not pull the power cord when unplugging.
Hold the power plug to unplug.
An electric shock or short circuit may cause a fire.

DANGER HAND

Do not insert your hand under the washing machine during
operation.
There is a rotary part under the machine which may cause
an injury.

WATER LEAKAGE

Before starting washing, open the faucet and check water
