Information
Code
- The part of the hose where the water level sensor
is located is damaged (punctured).
- The hose is clogged with foreign material.
- The hose is folded.
- Too much lubricant has been applied to the
1C
insertion part of the air hose.
- Hose engagement error (disengaged)
- Part fault (Faulty internal soldering)
- The water level sensor terminal is disengaged.
- Main PBA fault
-
The PBA connector terminal is not connected.
- The motor spin net is not engaged.
- The motor's internal coil is damaged (short-
3C
circuited or cut)
- Foreign material (a screw) has entered the motor.
- Constrain because of Foreign material between
PULSATOR and BOWL
- Motor overloaded due to too much laundry (Non
sensing)
3C1
- PBA fault
- The motor driving error from the PBA is weak :
3C2
Unstable relay operation, etc.
- The IPM terminal of the main PBA is not
connected.
3C3
- The DD motor cover is out of place.
- The PCB housing terminal is not connected.
3C4 - PBA fault
- DD motor fault
- PBA fault
3CP
- Pulsator motor fault
- Foreign material is entering the water supply valve.
- The water supply valve terminal is not connected.
(Wire disconnected)
- The warm water and rinse connectors are wrongly
connected to each other.
- This occurs if the PCB terminal from the drain
4C
hose to the detergent drawer is not connected.
Check whether the transparent hose is folded or
torn.
- This occurs Water pressure is weak, a certain time
delay.
- This occurs Water Valve by freezing in winter
season.
- T he water temperature is sensed as higher than
4C2
50 ˚C in the Wool or Lingerie courses
- The pump motor impeller is damaged internally.
- The wrong voltage (220 V → 110 V) is supplied to
the parts.
- Part fault
- This occurs due to freezing in the winter season.
5C
- The drain hose is clogged. (Injection error, foreign
material)
- Clogged with foreign material.
- The water pump terminal is not connected : rubber
band, bills, cotton, hair pins, coins.
