2) If there is no motor-working sound;

Check frequency of the Ball Pressure
Sensor (Pressure Switch), under no
load, or

Check contact defect of the safety
switch, defect of connection parts and
whether the lid is open if door error is
displayed.

Is placed the magnetic in Lid.

Check resistance of the motor.

1. In the case the motor rotates but the

inner tub does not rotates;

1) Check resistance of the drain motor if

the drain motor doesn’t work,or

2) Check gap between the PV link and the

brake lever if the inner tub does not
rotates while the drain motor works.

Less than  26.3 kHz

Reconnect the conncetors.

Explain “The lid is close

Change the Lid

Change the Ball Pressure
Sensor (Safety Switch).

Change the motor.

Change the drain motor.

Change the controller after
checking connection parts.

Reassemble the drain
motor or the clutch to
keep the clearance.

Change the clutch.

Where, what & how to check?

Result of Check

Possible Cause

How to repair & settle

1. Check voltage at the power outlet where

the washer is plugged into. 

1. Check the capacitance of the starting

capacitor.

1. Check the clearance between the PV

link and the brake lever and clearance
between the clutch lever and the
adjustment bolt.

1. Check whether the PV asm, the drain

pump & the drain hose are blocked by
foreign objects so that it makes water-
splashing noise in the tub.

Less than 85% of
rating

Lack of capacitance

The clearance is less
than 2.0mm or more
than 3.5mm

Bolt clearance is out
of range 1.9 

0.1mm

Tool low voltage

Defect of capacitor

Defect of the clutch

Explain the cause and
recommend using a
transfomerformer if
necessary.

Change the capacitor

Adjust PV lever bolt and paint
it red.
Reassemble the drain motor
or the clutch.

Adjust the bolt clearance.

Remove the foreign
objects.

Where, what & how to check?

Result of Check

Possible Cause

How to repair & settle

1. Check whether the washer is leveled.

(Check clearance with out tub and out
case the left gap is the same as the right
and the rear gap is 1.5~2 time bigger
than the front gap, between the cabinet
and the wash bowl, when it is leveled.)

2. Check whether laundry in the wash bowl

is out of balance that can cause severe
vibration & noise.

3. Check whether the pulsator doesn’t

rotate during spin.(To check that,
remove the front lid and than run the
spin only cycle.)

Not leveled.

Laundry is
unbalanced.

The pulsator rotates
initially then the inner
tub rotates.

Defect of installation

Defect of the clutch

Level the washer.

Explain that it is not out of
order and it may happen
when big & long laundry is
washed.

Change the clutch spring-B
or the clutch asm.

Result of Check

Possible Cause

How to repair & settle

1. Check whether the lever of the safety

switch touchs the outer tub if touching
noise happens.

1. Check whether the outer tub cover hit

the top cover without load during spin.

The lever is bented

Hit

Defect of the safety switch

Defect of the damper

Change the safety switch.
Don’t repair and reuse it
because it creates another
problem if it is wrongly
repaired.

Change four dampers
simultaneously.
In assembling, check
the position to damper
asm)

Where, what & how to check?

Result of Check

Possible Cause

How to repair & settle

1. It is mostly caused by noise from mains

or transfomerient power cut.

1. Check whether power is automatically

turned off when turning on the POWER
switch after unplugging the power cord
from the outlet

2. It would be defect of the controller if

power is automatically turned off
immediately when turning on the power
switch even though there is no defects
in the POWER switch.

Automatically turned
off.

Defect in main.

Mechanical defect of the
POWER switch.

Explain the cause. (It
happens specially when a
high frequency equipment is
a used around the washer or
in the case voltage fluctuation
is big)

Change the POWER switch.

Change the controller.

It is very important to find out what kinds of noise & where comes from to settle noise during spin and accumulately service
experiance.
