Code
- The signals between the sub and main PBAs are not
sensed because of a communications error.
- Check the connector connections between the sub
AC and main PBAs carefully. → Check for incorrect or
loose connections, etc.
- Remove the sub PBA C/Panel and check for any faulty
soldering.
- A button other than the Power button is continually
pressed (for more than 30 seconds).
BC2 - Deformation of an internal plastic injection part.
- A screw for assembling the sub PBA is tightened too
much.
- When the temperature of the water is greater than or
equal to 55 ℃, this code appears when the machine
does not drain. (reason : It is unsafe for hot water to
CC
drain as may burn if touched).
- Temperature sensor fault, or incorrect use.
- A switch contact error because of a deformation of the
door hook.
- When the door is pulled by force.
dC
- This occurs in the hot washes because the door is
pushed due to a pressure difference from internal
temperature changes.
- S/W contact fault because of LID TC "L" transformation.
- The door lock switch terminal is connected incorrectly.
- The door lock switch terminal is broken.
dC1
- This occurs due to Low insualtion of the wiring assy
- Main PCB fault
- This occurs if the Power switch is turned on/off
dC2 continually and too much heat is generated (This error
is difficult to be reproduced.)
HC - The washing heater is short-circuited or has a wire
disconnected.
- The washing heater in the tub has an error.(Contact
error, temperature sensor fault)
- If the water level sensor operates without water
because water is frozen or for any other reason and
HC1
the temperature sensor engaged at the bottom to
prevent overheating for the washing heater detects
a temperature of 100 to 150 ˚C, the washing machine
turns the input power off.
- This error occurs when the red temperature sensor at
the center of the dry heater operates (at a temperature
higher than 145 ˚C)
: C orrective action – Press the button at the center
lightly.
HC2
The washing machine will operate normally.
Alternatively, replace the temperature sensor ifthe
temperature sensing is unstable because of functional
degradation.
Causes Corrective Actions
• M ain PCB and Sub PCB Signal
Detection fault.
• M ain PCB and Sub PCB wire
connection fault.
• When pressed Power button.
• W hen pressed button except for
power button.
• Main PCB relay fault.
• W ashing temperature sensor
check.
• D escription PL Accident
prevention.
• Door lock switch fault.
• Drain pump fault.
• Dry duct fan motor fault.
• Main PCB fault .
• Heater fault.
• R ed temperature sensor at the
center of the dry heater.
• Steam function fault.
• Freezing by winter season.
