6-3. DETAILED DIAGNOSIS
1. Driving Compartment Test Mode
A. Hold down the 2 and the 3 buttons simultaneously and then press the Power button 11.
(All of the LEDs light up and the display shows t1 in 2 seconds.)
B. The driving part can be tested when you press the push button dial 11 right after entering into the TEST MODE.
No Check Test Method Description
1
Motor
Check if the motor operates or check the
Motor terminals.
Motor Wiring (Red/White /Blue/Pink/Violet/White)
Resistance between Blue-Red, Red-White
and White-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
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.
