water washing.
(Open circuit of water heater circuit.)
• Check the relay connector has not come
off or if contact failure.
• Open circuit failure of the relay.
Power button off and
on again.
(Short circuit of water heater circuit.)
• Short circuit failure of the relay.
Not necessary (In
case of short ciruit).
* unit automatically
off the operation.

on again.
H42 No-water heating of
water heater. 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. • Find out the cause of no-water heating,
such as clogging of the air trap, and
take necessary action.
Power button off and
on again.
H44 Abnormal vibration. Detected the number of drum rotations
decreases 100 rpm or more.
(Compared to the specified drum rotaions
that is reached during Spin operation.) • Check the clothes lean to one side.
• Replace the 3D sensor(Acceleration
sensor).
• Replace the motor.
• Replace the controller unit(Power side).

operation and
unnecessary to clear
the error.
H51 Overload on the motor. Data from the Rotation sensor are not
obtained for 2 minutes during washing
(motor on condition).
(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.

high voltage. Input voltage is 310V or more.
• Error data is memorized only.
• Error is not displayed.
• Check the power supply voltage.
• If the power supply voltage is normal,
replace the controller unit(Power side).
Not necessary
*Unit automatically
off the operation.
H53 Supplied abnormal low
voltage. Input voltage is 130V or less. • Check the power supply voltage.
• If the power supply voltage is normal,
replace the controller unit(Power side).
Power button off and
on again.
H57 Demagnetizing current
failure.
(Washing Motor) The demagnetization current detection
circuit operates the specified times during
the washing process. • Check the operation of the washing
motor and replace it if necessary.
• Replace the controller unit(Power side).

on again.
H59 Demagnetizing current
failure. (Circulation fan
motor) The demagnetization current detection
circuit operates the specified times during
the fan motor operation. • Check the operation of the circulation
fan motor and replace it if necessary.
• Replace the controller unit(Power side).
Power button off and
on again.
Malfunction of
Circulation fan motor.
