Causes Corrective Actions
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
6
SWITCH
(Main relay )
BC2
- 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.
• When pressed Power button
• When pressed button except
for power button
• Main PCB relay fault
7 COOLING CC
- When the temperature of the washing is greater
than or equal to 55
℃
, Appears when do not drain.
(reason : When hot water drainage Can cause
burns if it touches the body)
- When the water temperature is more than 55
℃
in
a particular course, proceeds the drain until reset
water level
- Temperature sensor fault, or incorrect use.
• Washing temperature sensor
check
• Description PL Accident
prevention
8 DOOR
dC
- A switch contact error because of a deformation of
the door hook.
- When the door is pulled by force.
- This occurs in the Boil wash because the door is
pushed due to a pressure difference from internal
temperature changes.
- S/W contact fault because of LID TC “L”
transformation.
• Door lock switch fault
• Drain pump fault
• Dry duct fan motor fault
• Main PCB fault
dC1
- The door lock switch terminal is connected
incorrectly.
- The door lock switch terminal is broken.
- This occurs intermittently because of an electric
wire leakage.
- Main PCB fault
dC2
- This occurs if the Power switch is turned on/off
continually and too much heat is generated (This
error is difficult to be reproduced.)
9 HEATER
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 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.
• Heater fault
• Red temperature sensor at the
center of the dry heater
• Steam function fault
• Freezing by winter season
HC1
HC2
- This error occurs when the red temperature sensor
at the center of the dry heater operates (at a
temperature higher than 145 ˚C)
: Corrective action – Press the button at the center
lightly.
The washing machine will operate normally.
Alternatively, replace the temperature sensor
ifthe temperature sensing is unstable because of
functional degradation.
