AC 220-240V

BLACK

When checking the voltage between
connector during whites washing. is the
voltage 127V~?

After power off, is the resistance of wire
(YELLOW-BLACK) connectors between
10Ω~30Ω?

After power off and the heater terminal is
disconnected, is the resistance 10Ω~30Ω?

When pressing Water Temp. during, is the
displayed temperature is over 10

higher

than the selected temp?

Is the resistance between Thermistor
Comectors 2.5kΩ~180kΩ)

When checking THERMISTOR on the tub is the
THERMISTOR loosened above 2mm from the
rubber?

Replace the MAIN PWB
ASSEMBLY.

Normal

Replace the HEATER
ASSEMBLY.

Check if inlet hose is
connected to a hot
faucet; otherwise, replace
PWB ASSEMBLY(Main)

Replace Thermister

Push the THERMISTOR
tightly to the rubber.

Check on the spinning, is the frequency of the
water level 248 or more. The frequency can be
checked by pressing the Rinse and Spin
buttons at the same time on the program.

When pressing Rinse, Spin and POWER
buttons at the same time after power off,
press the Start/Pause button 1 times, is the
drum low speed spin?

Is it disconnected, or disassembled?
[Red:3pin(1), GY:4pin(2)]

Replace the MAIN PWB ASSEMBLY

Resistance of terminal:

: About 5 Ω ~ 15 Ω

Check the motor connector, is the resistance of
the terminal same as the figure?
MOTOR TERMINAL (1)

Does the spring of Latch Hook actuate?

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

Is DOOR SWITCH ASSEMBLY broken?

Check the S.PRESSURE SWITCH 
ASSEMBLY or HOSE (Pressure).
