1. Check whether the drain hose is laying

down on the floor. 

2. Check where water leaks.

1. Check the pulsator is rotating when

water fills continuously.

2. If there is no defect in the Ball Pressure

Sensor(Pressure Switch), check
whether the air hole of the outer tub is
blocked. 

1. Does water fills even though it is not

energized (power is off)?

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.

Water fills.

Wrong installation.

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 (Pressure
Switch), it is bent or blocked,
repair that.

Repair the blocked hole.

Change the inlet valve.

Change the controller.

How to repair & settle

1. Is there PE error on the display which

means Ball Pressure Senosr (Pressure
Switch) error

2. Check frequency of the Ball Pressure

Sensor(Pressure Switch) without load if
wash is proceeding without filling.

1. Defect of controller is highly possible if

inlet valve and Ball Pressure Sensor
have no defects in the above.

PE Error displayed.

Less then 26.2 kHz

Connector is taken off, or
lead or coil is open.

Defect of the Ball Pressure
Sensor (Pressure Switch)

Reconnect the connector or
change leads. Change the
Ball Pressure Sensor
(Pressure Switch) if coil is
open.

Change the Ball Pressure
Sensor (Pressure Switch).

Change the controller.

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 motorworking 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.

∞ Ω

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.

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.

1. Check whether the drain hose is put in a

narrow space and kinked.

2. Check whether the drain hose is

blocked by foreign objects. It may

happen in case of the hose is a little

kinked.

There is pump

working sound.

∞ Ω

Defect in connection

part.

Connection part has

no defects.

Kinked.

Blocked.

Drain pump is blocked by

foreign objects.

It’s coil is open.

Defect in connection part.

Defect of the controller.

Defect of installation.

Blocked hose.

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.

Remove the objects and

reinstall so that it can’t

be kinked.

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

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.

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.

1. Check whether the drain motor or the

drain pump works immediately after
power is turned on.

Blocked.

Bellows deformed.

Defect of PV Bellows.

Defect of the controller
(Triac defect)

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)

1. In the case that the wash motor does

not  spin during spin extraction;

1) Check there is motor working  sound,or

There is motor
working sound.

Defect of the capacitor or
Mechanically locked.

Change the capacitor after
checking defect of
capacitor. check whether
the washing clutch or the
washing tub is blocked if the
motor rotates after removing
the V-belt. Check whether
the motor is locked if the
motor does not rotates even
though the V-belt being
removed.
