4-6. HOW TO DIAGNOSE AND REPAIR BY SYMPTOM
1) Washer is not energized.
Where, what & how to check?
Result of Check
Possible Cause
How to repair & settle
Household Power supply
1. Check whether connection between the
plug and the electrical is poor
2. Measure voltage of the electrical.
Wiring of the Washer
1. Measure resistance between both ends
of the power supply cord with both the
plug pins short-circuited.
2. Check whether every connector in the
bundle of connectors has a good
connection.
3. Check resistance of every wire to find
out a open wire.
Electrical component
1. Check resistance with power relay
switch turned on
2. Check the secondary voltage of the
transfomer.
3. Check whether the fuse is open.
Controller
If there are no defects in the above, 
it should be defect of the controller.

Switch
Change the
transfomerformer.
Change the fuse.

2) Defects on displaying funcion
Where, what & how to check?
Result of Check
Possible Cause
How to repair & settle
Main voltage
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.
Controller
1. Defect of LED.
2. Defect of LED driving circuit.
3. Defect of micom.
Less than 85% of the
rating
Less than 85% of the
rating
Low voltage
The dia of the lead wire is
smaller or many loads are
connected at the same
outlet
Defect of controller.
Change the 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.
3) Reset During operation
Where, what & how to check?
Result of Check
Possible Cause
How to repair & settle
Main voltage
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)
Controller
1. If mains voltage and the drain motor
have no defects a defect of the controller
is highly possible.
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.
Change the controller.
