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.

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.

2-2

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.

3-2-1. Level Specifications and Wall - Clearance Distances

1) Install the washing machine on a solid and level floor.

2) Place the machine at least 15cm away from the wall.

3) Placement on an inclined, weak or rough floor may
cause abnormal noise or trembling.

3-2-2. Positioning the Drain Hose

1)When there is no threshold, the length of the
drain hose should not exceed 3m.

2)When it is necessary to connect the drain hose
with the drain outlet far away, connect the
extension hose and
applicable parts
available from
dealers or service
centers.

3) Do not install the drain hose where it must exceed
over a threshold of 3cm or more ; do not install

where there is a

threshold
and the hose
must exceed for
more than 2m.

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)

7. CHECK POINT AFTER REPAIR

After repairing, be sure to make the following trial operation to see if the washer operates normally.

Check Point Inspection & Judgement

1) Insulation resistance Unplug the cord from the power outlet and turn on all the timers. Then
measure the insulation resistance between the plug (both of 2 pins) and
grounding wire of the machine.
The measured value should be more than1MΩ􀈳
In the following case, check sufficiently.

1)Replace the electrical parts with new ones.

2) Used in a moist place.

3)Used more than 5 years.

2) Safety device Check the full stop time of the spin basket.
Braking time should be as follows.

3) Safety designated

parts

Replace with the designated parts in the case the used parts are not proper.
(Refer to '*" marked parts in the parts list)

4) Wiring Check to see if the lead wire is properly connected without looseness or
overtension and taping and setting are firmly performed.

5) Screws and Nuts Check to see if the screws, nuts, etc. are firmly tightened and the screw locks
are
applied.

6) Removal of useless

matter

Check to see if useless matters (Screws, bits of wire, etc.) are left inside the
machine.

7) Leakage of oil and

water

Check to see if oil or water leaks out around bellow-spinning, gear box, motors
and connection of d.v-case.

8) Power-cord Check to see if the cord, the plug, the outlet etc, are not damaged. Do not use
table
Tape with multi-wiring.

9) Level Installation Check to see if the machine installed horizontally.
