Causes
Corrective Actions
1
Water Level
1C
- 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
part of the air hose.
- Hose engagement error. (disengaged)
- Part fault. (Faulty internal soldering)
- The water level sensor terminal is disengaged.
- Main PBA fault.
• Water level sensor fault.
• The water level sensor terminal is
disengaged.
• The part of the hose where the
water level sensor folded.
• Main PCB fault.
2
Motor
3C
- The PBA connector terminal is not connected.
- The motor spin net is not engaged.
- The motor’s internal coil is damaged. (short-circuited
or cut)
- Foreign material (a screw) has entered the motor.
- Constrain because of Foreign material between
PULSATOR and BOWL.
• Washing motor fault.
• Check Washing motor connector.
• Washing motor rotor/stator fault.
• Main PCB fault.
3C1
- Motor overloaded due to too much laundry. (Non
sensing)
- PBA fault.
3C2
- The motor driving error from the PBA is weak :
Unstable relay operation, etc.
3C3
- The IPM terminal of the main PBA is not connected.
- The DD motor cover is out of place.
3C4
- The PCB housing terminal is not connected.
- PBA fault.
- DD motor fault.
3
Water Supply
4C
- 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 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.
• Water supply valve fault.
• Main PCB fault.
• Freezing by winter season.
4C2
- The water temperature is sensed as higher than 50 ˚C
in the Wool or Lingerie courses.
-
4
Drain
5C
- 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.
- 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.
• Drain pump fault.
• Freezing by winter season.
• Check inside foreign material of
drain pump.
• Main PCB fault.
5
Communication
AC
- The signals between the sub and main PBAs are not
sensed because of a communications error.
- Check the connector connections between the sub
and main PBAs carefully. → Check for incorrect or
loose connections, etc.
- Remove the sub PBA C/Panel and check for any faulty
soldering.
• Main PCB and Sub PCB Signal
Detection fault.
• Main PCB and Sub PCB wire
connection fault .
