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.
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

13) Vibration, Noise or Unbalance Error happens during spin.
Where, what & how to check?
Result of Check
Possible Cause How to repair & settle
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.)
Safety Switch
1. Check whether the lever of the
safety switch touchs the outer tub if
touching noise happens.
Damper
1. Check whether the outer tub cover 
hit the top cover without load
during spin. 
Not leveled.
Laundry is 
unbalanced.
The pulsator 
rotates initially 
then the inner tub
rotates.
The lever is
bented
Hit
Defect of 
installation
Defect of the 
clutch
Defect of the
safety switch
Defect of the 
damper
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.
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)
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.
