Detection contents
Open circuit or short circuit is caused in the
water heater circuit.
• Heater is not conducting in warm water
washing.
• Heater is conducting in except of warm
water washing.
The number of fan motor rotation is less
than 1,200rpm continuously for 30 seconds
during fan operation.
*The number of drum rotations is 2,000rpm
or more.
*Braking time is the specified time or less.
Bubble sensor 2 circuit had over or under
output voltage than specified data.
Bubble sensor 1 circuit had over or under
output voltage than specified data.
Data from the sensor are not obtained for
30 seconds during Spin operation.
Rapid temperature rise is detected.
(From 1minute 20 seconds after water
supply agitation has sterted during warm
water washing.)
It judge there is no water in the drum.
Detected the number of drum rotations
decreases 100 rpm or more.
(Compared to the specified drum rotaions
that is reached during Spin operation.)
Open circuit or short circuit is caused in the
P.C.board thermistor.
• Error data is memorized only.
• Error is not displayed.
obtained for 2 minutes during washing
(motor on condition).
Input voltage is 310V or more.
• Error data is memorized only.
• Error is not displayed.
Input voltage is 130V or less.
The demagnetization current detection
circuit operates the specified times during
the washing process.
The demagnetization current detection
circuit operates the specified times during
the fan motor operation.
The number of the circulation fan rotations
does not reach the rated number of
rotations.
Check point
(Open circuit of water heater circuit.)
• Check the relay connector has not come
off or if contact failure.
• Open circuit failure of the relay.
(Short circuit of water heater circuit.)
• Short circuit failure of the relay.
• Chenk the connector has not come off.
• Check the contact failure of connector.
• Replace the fan.
• Reset the V belt.

• Check the installation condition of the
motor.
• Replace the controller unit(Power side). Power button off and
• Replace the controller unit(Power side). Power button off and
• Check the connector has not come off.
• Check the contact failure of connector.
• Check the breakage of lead wire.
• Replace the 3D sensor(Acceleration
sensor)
• Find out the cause of no-water heating,
such as clogging of the air trap, and
take necessary action.
• Check the clothes lean to one side.
• Replace the 3D sensor(Acceleration
sensor).
• Replace the motor.
• Replace the controller unit(Power side).
• Replace the controller unit(Power side). Continued the
(Motor is not rotating)
• Replace the controller unit(Power side),
if there is no operation output from
controller to motor.
• Replace the motor, if there is operation
output from controller to motor.
(Motor is rotating)
• Check the Rotation sensor connector
has not come off.
• Replace the motor, if the connector has
not come off.
• Check the power supply voltage.
• If the power supply voltage is normal,
replace the controller unit(Power side).
• Check the power supply voltage.
• If the power supply voltage is normal,
replace the controller unit(Power side).
• Check the operation of the washing
motor and replace it if necessary.
• Replace the controller unit(Power side).
