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 insertion
1C
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.
3C
- The motor's internal coil is damaged (short-circuited
or cut)
- Foreign material (a screw) has entered the motor.
- 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
- 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.
4C
- This occurs if the PCB terminal from the drain 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 50 ˚C
4C2
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.
