Check the connectors at the
main PCB, the heater and the
thermistor. Are the
connectors loose or
disconnected?

Is the connector connected to
thermistor disconnected or
disassembled?

[Note]
The temperature sensing circuits on the main
PCB are very simple, consisting only of resistors
and capacitors. Problems with wiring or
connections in the thermistor circuit are the
most likely cause for this error. Be sure to
check ALL connections and wiring thoroughly.
The main PCB should only be replaces as a last
resort, as it is unlikely to be the cause.

Check the thermistor
resistance. Is the resistance
correct according to the
chart?

(Refer to 9-7 thermistor
assembly.)

Are the thermistor terminals
dry and free of corrosion?

Check the resistance of the
heater. Is the resistance
between 12

and 18

?

(Refer to 9-6 Heater
assembly.)

THERMISTOR
ASSEMBLY.

Reconnect or
repair
the connector.

Proceed to next step at right

Check the connectors below.
Is the connector disconnected
or disassembled?
(motor hall sensor connector,
motor drive connector.)
- part of main PWB

Reconnect
the connector.
(connector /
wire / motor )

Replace
the ROTOR.

Is rotor magnet cracked?

Magnet

Replace
the STATOR.

Is the resistance values
in the range of 5 to 15 

Ω?

(U-V, V-W, W-V
:U=1, V=2, W=3)
- After pull out the RD4

connector, check the
terminal of the connector
in wire. (Red 3P, male)

Replace
the Hall
sensor.

Is hall sensor out of
order? 

(Refer to 9-3

Stator assembly/Hall
sensor.)

Replace the
MAIN PWB
ASSEMBLY.

Check the IPM in the
controller.

Is the connector connected
to door switch or main PWB
disconnected?

Reconnect or
repair
the connector.

Is there clicking sound once
or twice when the
START/PAUSE button is
pressed to start the cycle?

Replace the
PCB
ASSEMBLY.

Is DOOR SWITCH
ASSEMBLY broken?

Replace the
DOOR
SWITCH
ASSEMBLY.

Does the spring of Latch
Hook actuate?

Replace
Door
Assembly.

[Note] Environmental check list
1) The machine must operate with all the doors

completely closed and locked.

2) The washing area must operate with a water

temperature not higher than 45 Celsius and
must not have more amount of supplied water
than it should.
