Inlet Valve
1. If water doesn’t come though the 
inlet valve works(electric sound 
occurs)
1) Check whether water mains is cut.
2) Check whether tabs are turned on.
3) Hot & cold tab are opposite
connected.
4) Wrongly select water temperature
option.
5) If there are no problems in the 
above, check the inlet valve filters 
after disconnecting the water supply
hoses.
6) If there are no problems in the 
above a diaphragm hole in the valve
is blocked  by foreign substance or 
the plunger in it is locked.
2. If the inlet valve doesn’t work(there 
is no electric sound)during filling 
cycle.
1) Check whether it’s connectors are 
taken off or they have poor 
connection. 
2) Check resistance of the inlet valve.

Drain Motor
1. Operate washer setting spin only, 
then  press the start/pause button 
when the  wash motor starts to work 
and then press the start/pause 
button again in order for the drain 
motor to work intermittently.
Controller
1. If mains voltage and the drain motor 
have no defects a defect of the 
controller is highly possible.
Reset happens
after the drain
motor works.
Defect of the drain 
motor (A noise 
generated when the 
internal relay 
works.)
Change the drain motor
Change the controller.
3) Reset during operation

Wrong Installation/Leakage
1. Check whether the drain hose is 
laying down on the floor. 
(For pump model)
2. Check where water leaks.
Ball Pressure Sensor
1. Check the pulsator is rotating when 
water fills continuously.
2. If there is no defect in the Ball
Pressure Sensor, check whether the
air hole of the outer tub is blocked.
Inlet Valve
1. Does water fills even though it is not
energized (power is off)?
Controller
1. Does water fill immediately after the
power switch turns on before pushing 
the start/pause button.
Drain hose 
laying down.
Water leaks 
from a part.
It doesn’t 
rotate.
Blocked.

Defect of the part.
Water pressure is
not sensed.
Air hole blocked.
Defect of the inlet
valve.
Short circuit of the 
triac of the 
controller.
The drain hose 
should be hung on the 
stand-pipe or the tub.
Change the part.
Repair it.
Check the tube of the  
Ball Pressure Sensor, it
is bent
or blocked, repair that.
Repair the blocked hole.
Change the inlet valve.
Change the controller.

Ball Pressure Sensor
1. Is there PE error on the display 
which means Ball Pressure Senosr
error
2. Check frequency of the Ball
Pressure Sensor without load if
wash is proceeding without filling.
Controller
1. Defect of controller is highly possible
if inlet valve and Ball Pressure
Sensor have no defects in the
above.
Reconnect the connector
or change leads. Change
the Ball Pressure Sensor
if coil is open. 
Change the pressure
switch.
Change the controller.

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.

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
