6-3. DETAILED DIAGNOSIS
No Check Test Method Description
1 Motor
Check if the motor operates or check
the Motor terminals.
Motor Wiring (Red/White①
/Blue/Pink/Violet/White②)
Resistance between Blue-Red, Red-White①
and White①-Blue should be 2.0Ω±10%.
2
Water
Valve
Check if it supplies water or check the
Water Valve terminals.
Check resistance of the Water Valve
terminals.
3 Drain Pump
Check if it drains normally or check
the pump terminals.
Check resistance of the Drain Pump
terminals.
4 Door S/W
Check if it works at the Cotton course
or check the Door S/W terminals.
Check resistance of the Door S/W terminals.
5 Heater
Check if it works by changing
temperatures at the Cotton course.
Check resistance of the Heater terminals.
6
Water
Pressure
Sensor
Refer to Page 14.
(Water Level Table at each Course)
Check frequency (Hz) between the Water
Pressure Sensor terminals.
7 Thermistor Check its resistance.
It varies according to temperatures.
(If it is ∞ or 0, replace it.)
8 MAIN PCB
1.Press the buttons on the display.
Check if all of the LEDs work.
2.Check if voltage between the white
and the black terminals is 220V~240V.
1.Replace the SUB PCB.
2.If not, replace the Noise Filter.
