1. Precautions

When performing trouble - shooting 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
used when replacing parts. In particular, be sure to use
only designated parts in case of major safety parts
identified by the making.

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 ground it to the telephone line, lightning rod,

or gas pipe.

1-2 Servicing Precautions

1-2-1 Observe warnings

Be sure to follow special warnings and precautions that
are described on part labels and in the owner's manual.

1-2-2 Special Precautions for Parts Assembly

and wiring

When assembling parts that use safety - insulation
material (such as tube and tape), or when installing
internal wiring, be sure to restore all parts and wiring to
their original positions.
Take special care to avoid contact with sharp edges.

1-2-3 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 1û of grade) to prevent
vibration and noise during operations.

1-2-4 Insulation Check

Pull out the plug from the power receptacle, pour water
into the spin tub, and then set the timer. Check to see
that the insulation resistance between the terminals of
the plug and the exposed metal is greater, than 1 M½.

Note : When it is impossible to perform the insulation

check with a 500V insulation resistance tester,
use other testers for inspection.

4-4 Description of Technical Points

4-4-1 Weight Recognizing Function

1. Weight recognizing function works first washing
operating before water is supplied, not in WOOL
course and Manual function operation (Wash,
Rinse, Spin, •••)

2. Weight recognizing function is cancelled when
water level key is pressed prior to the completion of
weight recognizing function.

3. If the current water level is above lowest at the
beginning of weight sensing, it is automatically
decided as a high level.

4. If you change courses after sensing weight, the high
water level is automatically selected irrespective of
the water level decided by the sensing of weight.

4-4-2 Water Supplying Function

1. Relations between water level, frequency & water
supply capacity.

2. Relations between Hot/Cold selection & cycle.

3. If the water level does not reach to the water level
selected for 60minutes after starting water
supplying, the water supplying Error is displaying
on the display.

4. Supplementary water supplying is performed
every Washing or Rinsing operating. The steps are
as follows.

● supply water to the water level selected,

● perform the washing or Rinsing operation for 1.5

minutes.

● sense the present water level after stopping

Motor.

● compare the present water level to the water

level selected.

● if present water level < the water level selected,

supply water to the water level selected.

if present water level ≥the water level selected,

continue the washing or Rinsing operation.

● But total time of supplementary water

supplying is not over 30 seconds.

4-4-3 Soak Function

1. This course works only when Soak washing is
selected by course select key.

2. It works repeatedly during set time by every 5
minutes(operation for 1 minute and pause for 4
minutes) for 30 minutes after water is filled to
selected water level.

3. If water level is set higher during the Soak
procedure, Soak procedure stops and water is
refilled, and then, keeps on going the Soak
procedure.

4. Washing cycle of 20 minutes begins after Soak
function completion.
Rinsing times can be adjusted according to Soak
washing procedure.

4-4-4 Fuzzy Function

This function recognizes the quantity of laundry
load and selects the water level by itself and keep
on going washing operation automatically.
