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.

Children may be injured with a tool or a disassembled part.
UNPLUG POWER
Unplug power cord for the work such as disassembling
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.
REMOVE DUST
Wipe off dust adhered to the plug of power cord.
Dust may cause a fire.
AVOID
INFLAMMABLE
Do not put inflammable into the washing tub.
Do not put cloths stained with kerosene, gasoline, benzene,
thinner, alcohol, etc. lt may cause a fire or explosion.
1 PRECAUTION

6
WARNING
DO NOT TOUCH
Do not touch the laundry before the spin basket stops
completely.
The laundry entangles your hand causing an injury even if
the basket rotates slowly. Pay special attention to children.
INSTALL
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
supply hose joint which shall not be loosened for no water
leaks.
The loose screw or hose joint may cause water leakage
resulting in an unexpected damage.

4.1 During the failure diagnosing and changing components, please do it as
following:
1)There is some static harm to the electrical parts from colophony in the
washing machine or humans. So it is better to eliminate the potential static by
grounding the humans or touching the plugs.
2)The rated voltage of the SCR in PCB is 220-240V, so it's possible to be electrical
shock. Please take care while strong and weak electricity is alternative. 3)The
design of PCB is out of failure, so prohibit to change the PCB panel according to
its alarm. Please do it according to the failure diagnose program.
