Motor
1. In the case that the wash motor
does not spin during spin extraction;
1) Check there is motor working
1) Check there is motor working
sound,or
2) If there is no motor-working
sound;
Check frequency of the
Ball Pressure Sensor, under
no load, or
Is placed the magnetic in
Lid-B.
Check resistance of the motor.
Drain Motor/Clutch
1. In the case the motor rotates but the
inner tub does not rotates;
1) Check resistance of the drain
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.

Main voltage
1. Check voltage at the power outlet
where the washer is plugged into.
Starting Capacitor
1. Check the capacitance of the
starting capacitor.
Clutch Assembling
1. Check the clearance between the
PV link and the brake lever and
clearance between the clutch lever
and the adjustment bolt.
Blocked by foreign objects
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.

Using conditions such as
installation etc.
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.)
Damper
1. Check whether the outer tub cover
hit the top cover without load
during spin.

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

14) Power is automatically turned off during operation or immediately
turning on the power switch.
Where, what & how to check?
Result of Check Possible Cause How to repair & settle
Main voltage
1. It is mostly caused by noise from
mains or transfomerient power cut.
Auto Off switch or
Controller
1.Check whether power is
automatically turned off when
turning on the auto off 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 auto off switch.
Automatically
turned off
Defect in main.
Mechanical defect
of the auto off
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 auto off
switch.
Change the controller.
