Error Type
Display
Causes
Remarks
Water Level
Sensor
- 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.
Motor Driving
Error and Hall
Sensor Error
- 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)
- The hall sensor terminal is not connected.
- Foreign material (e.g. a screw) has entered the motor.
This error occurs because of restrained
revolutions.
Water Supply
Error
- 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 incorrectly
switched with 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.
- The cold and warm water supply hoses are incorrectly
switched with each other.
The water supplied for 1 minute drying
cycle is 0.3 ~ 0.4 L.
- The water temperature is sensed as higher than 50 ˚C
in the Wool or Delicates/Hand wash for 8 seconds
Drain Error
- The pump motor impeller is damaged internally.
- 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)
- The water pump terminal is not connected: rubber
band, bills, cotton, hair pins, coins have collected
inside the drain pump ASSY.
Commnication
Error
- The signals between the sub and main PBAs are not
sensed because of commuication 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.
Switch Error
(Main Relay
Error)
- The Power button is pressed continually. (for more
than 12 seconds)
- A switch is jammed or stuck due to be pressed
unevenly due to deformation of the control panel or
button.
- This error may occur when the screws that hold the
sub PBA in place are tightened too much.
- A button other than the Power button is continually
pressed. (for more than 30 seconds).
- Deformation of an internal plastic injection part.
- A screw for assembling the sub PBA is tightened too
much.
