CONTENTS

1. PRECAUTION
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 withstanding. 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
1-2-1. Observe Warnings
Be sure to follow special warning and precautions that are described on part labels and in
the owner's 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 than 1(one) 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 perform insulation check with a 500V insulation
resistance tester, use other testers for inspection.

indicates prohibition (act must not be conducted).
Specific instruction is followed by a graphic or characters in or near
Symbol left warns not to disassemble.
UNPLUG
• indicates forcing (act must be conducted).
Specific instruction is followed by a graphic or characters in or near • .
Symbol left warns to unplug the power cord.
WARNING
OUT OF CHILD
• Advise the customer to keep children out of the work place.
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, a malfunction or a defect may occur.
Also, a short circuit, ignition or other danger to the customer may occur.

2. CAUTIONS FOR SAFETY
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 MODIFY
• Do not modify the product.
An electric shock or ignition may occur.
DO NOT
DISASSEMBLE AND
REPAIR
• 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.
(AW-B651B/B657B/B761S/B757S)
• Use an exclusive 220 VAC/17 A socket for the washing machine.(Except
above models)
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.

2. CAUTIONS FOR SAFETY
WARNING
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.
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.

3. DESCRIPTION OF PARTS
3-2-3. Grounding
1) Upon installing grounding,make sure if power socket is out
of power outlet.
2) Grounding should be connected to eithermetal water
supply
pipe or copper grounding pole deeper than 25cm in the damp
ground. (Fig 1)
3) If water pipe is a plastic, no protection is obtained from
a possible electric shock.
4) If the power outlet is available with grounding connection,
grounding in the washingmachine should be firmly connected
to
the connection of the outlet. (Fig 2)
5) You should not connect, the grounding to the gas-pipe
because
it will cause an explosion. (Fig 3)
6) If the grounding is connected to either telecommunication
line
or lightning-arrest line, an extreme hazard is caused therefore,
no connection should bemade to such lines. (Fig 4)
