Where, what & how to check?

Result of Check

Possible Cause

How to repair & settle

1. Measure mains voltage at the wall outlet

2. Meaure voltage at the extended
outlet that the washer is plugged in
if the extended outlet is used and
voltage at the electrical outlet
is normal in the above.

1. Measure the secondary voltage of the

transfomer.

2. Defect of LED driving circuit.
3. Defect of micom.

smaller or many loads are
connected at the same
outlet

Defect of the transfomer

Defect of controller.

To explain that it is
caused by low voltage in
electric supply and
recommend using a
transfomer if voltage has
been continuously low.

To use a transfomer
having a enough capacity
if using a transfomer.

Possible Cause

How to repair & settle

1. Measure voltage of the outlet that the

washer is plugged into during wash and
spin.

2. Reset symptom happens at specific time

zone repeatedly.

3. Check whether a transfomerlent power

cut happens. (Fluorescent lamp is
transfomeriently blinked)

Less than 80% of the
rating.

Mains voltage is too low
or size of a lead wire is
too small.

External noise inrushed.

Explain that it is caused
by low voltage in electric
mains and recommend
using a suitable size of
leads.

Explain it is caused by
using environment.
(It happens when
equipment with high
frequency is used
around)

Explain it is a problem of
electric supply
environment.

Result of Check

Possible Cause

How to repair & settle

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.

Water mains cut.

Dont tumed on.

Connected opposite.

Selected opposite.

Filters blocked by

foreign substance.

A connector is taken

off.

∞ Ω

Mains cut.

Mistake of use.

Wrong installation.

Mistake of use.

Don’t clean.

Defect of the inlet valve.

Defect of contact.

Coil is open

Explain.

Turn on the tap.

Correct their locations and

turn on the tap.

Explain how to use.

Clean them by brush and

explain cleaning regulary

them.

Change the inlet valve.

Reconnect it or remove

the causes to make poor

connection.

Change the inlet valve.

Result of Check

Possible Cause

How to repair & settle

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.

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.

Where, what & how to check?

Result of Check

Possible Cause

How to repair & settle

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.

Where, what & how to check?

Result of Check

Possible Cause

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.

Result of Check

Possible Cause

How to repair & settle

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
