Main v
oltage
1. Measure mains voltage at the wall
outlet.
2. Measure 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.
To explain that it is
caused by low voltage in
electric supply and
recommend using a
transformer if voltage has
been continuously low.
To use a transformer
having enough
capacity if using
a transformer.
Change the controller.

Mains Voltage
1. Measure voltage of the outlet that the
washer is plugged into during wash and
spin.
2. Reset symptom happens at specific
time of day repeatedly.
3. Check for brown-out or power cut.
Less than
80% of the rating.
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
