6) Pulsator doesn’t rotate normally.
Where, what & how to check?
Result of Check
Possible Cause How to repair & settle
Pulsator rotates at one 
direction
.
1. The Pulsator rotates normally at the 
beginning of wash cycle, but is it not
rotate at clockwise direction (locked) 
after some wash cycles though there
is motor-working sound?
2. In the case the pulsator doesn’t 
rotates either clockwise or 
counterclockwise from the beginning
of wash cycle:
1) Check resistance of the wash 
motor if there is no motor-working
sound.
2) Check belt tension & whether the 
clutch rotates normally if there is 
motor-working sound.
3. The pulsator doesn’t rotate at both 
directions.
1) Check whether motor rotates at 
both directions if there is motor-
working sound when it’s 
energized.
2) Check resistance of the motor if 
there is no motor-working sound.
Clockwise
rotation locked.
Resistance 
is normal.
V-belt is loose.
Clutch locked.
Motor rotates 
at both
directions.
Motor doesn’t 
rotates at both
directions.
Normal 
resistance.
Unusual operation.
Defect of 
controller or poor 
contact of 
connectors of 
motor leads.
Loose the belt.
Defect of the
clutch.
Loose the belt.
The plusator 
locked.
Defect of the 
clutch.
Defect of the 
capacitor.(check
the capacitor’s 
capacitance)
Defect of the
motor. 
Motor coil is open.
Contact defect of
the leads.
Turn the power off 
and on again then that 
symptom disappears.
Explain “Don’t run wash 
only continuously”.
Change the controller if 
there are no contact 
defects in the leads of
the motor.
Adjust belt tension by 
changing motor fixing 
location and change the 
belt if it is impossible to 
adjust belt tension. 
Change the clutch if the 
clutch pulley is locked 
when making it rotated 
clockwise and 
counterclockwise by 
hand.
Adjust belt tension or 
change the belt if it is 
impossible to adjust.
Remove cause 
locking the pulsator
Change the clutch.
Change the motor if the 
motor is locked when 
having its shaft rotated 
by hand.
Change the capacitor if 
there is no contact defect 
in capacitor’s lead
Change the motor.
Remove the causes.

4. Pulsator weakly rotates.
1) Check voltage at the power outlet
where the washer is plugged into.
2) Check capacitance of the 
capacitor.
Less than 85%
of rating.
Indicating 
needle rises and
immediately 
indicates 
The needle is
stopped after it
is raised.
The needle 
doesn’t move.
Lower voltage.
Capacitor is 
normal.
Lack of 
capacitance of the
capacitor.
Capacitor is fully
discharged.
Explain the causes and a
transfomer should be
used if necessary.
Change the capacitor. 
Change the capacitor.
7) Water does not drain.

Drain Pump
1. Check whether there is drain pump
working sound.
2. Check resistance between terminals
if there is no working sound of the 
drain pump.
3. Check connection parts of the leads 
if there is no working sound and its 
resistance is normal.
Drain Hose
1. Check whether the drain hose is put 
in a narrow space and kinked.
2. Check whether the internal drain 
rubber asm is bent.(For Non-pump 
model)
3. Check whether the end of the drain 
hose submerged into water or 
higher than required.
(For non-pump model)
There is pump
working sound.
Defect in 
connection part.
Connection part 
has no defects.
Kinked.
Bent.
Submerged or 
higher than 
required.
Drain pump is
blocked by foreign 
objects.
It’s coil is open.
Defect in 
connection part. 
Defect of the 
controller.
Defect of 
installation.
Defect of the drain
rubber asm.
Defect of 
installation. 
Disassemble the drain
pump cap and remove
the foreign objects in the
pump casing.
Change the drain pump.
Repair defected 
connection.
Change the controller.
Reinstall so that it should
not be kinked.
Change the drain rubber
asm.
Re-install so that it can’t 
be submerged or not 
higher than required.

4. Check whether the drain hose is 
blocked by foreign objects. It may 
happen in case of the hose is a little 
kinked.
PV Case
(for Non-Pump Model only)
1. Check whether the PV asm is
blocked by foreign objects.
Drain Motor
(For Non-Pump Model only)
1. Check resistance of the drain 
motor if it can not pull the PV link.
Blocked.
Blocked.
Resistance is 
normal.
Blocked hose.
Drain motor coil is
open.
Contact defect in 
connection parts 
or defect of the 
controller.
Remove the objects and
reinstall so that it can’t
be kinked.
Separate the drain motor
from the PV link,
disassemble PV cover
and then remove the
foreign objects within 
PV case.
Check the washer works
normally after repair 
and reassembling them.
(PV link & drain motor
lever should be 
assembled accuratel.)
Change the drain motor 
Check the washer 
works normally after 
reassembling.
(PV link & drain motor 
lever should be
assembled accurately.)
Change the controller if 
there is no defects in the
connection parts.

Drain Motor
(for Non-Pump Model only)
1. Check whether the drain motor is 
normally returned after turning 
power off.
(It is considered normal if the lever 
of the drain motor is fully pulled out 
by the PV spring)
PV Case
1. If water drains though the drain 
motor is normally returned, check 
whether PV asm is blocked by 
foreign objects or the bellows in 
the PV asm is deformed.
Controller
1. Check whether the drain motor or 
the drain pump works immediately
after power is turned on.
Blocked.
Blocked.
Bellows
deformed.
Works. 
Defect of the drain
motor.
Defect of PV 
Bellows.
Defect of the 
controller(Triac 
defect)
Change the drain motor.
Remove the objects in 
the PV asm.
Change the PV bellows.
(The bellows may swell 
up if it contact petroleum
or petrochemical 
substance because it is 
made of rubber)
Change the controller.
9) Drain error happens while water drains normally.
