Description of Photo
Switch
(Main Relay)
bC2
• The Power button is
continually pressed.
• A button other than the
Power button is continually
pressed.
• Main PCB relay fault
• Check whether either the Power
switch or a tact switch is continually
pressed.
• Check whether the service PBA
holding screws are fastened too
much. If they are fastened too
much, loosen them a little.
• If the main PBA switching IC on/
off error has occurred, replace the
main PBA.
Check the contact between the control panel buttons
and their corresponding tact switch.
- There must be a gap between a control panel
button and its corresponding micro switch.
Otherwise, an error occurs after approx. 30
seconds has passed.
GAP
Cooling
CC
• Washing Temperature
sensor fault
• Description of PL hazard
prevention
• This error occurs if the water
Temperature is more than 50 ˚C in
draining. Check the temperature.
• If the water temperature is normal,
this error is due to a temperature
sensor fault. Replace the washing
heater.
When replacing the washing
heater, take care to prevent water
leakage.
Check the resistance on the Heater.
(For faulty features)
Check the voltages both terminals of the Heater
while washing.
Check 25.19 ~ 27.84Ω on both terminals and the
voltage of the Heater.
Door
dC
dC1
dC2
• Door switch fault
• Main PCB fault
• If a dC error occurs, check whether
it occurs during the Boil cycle.
- If it is detected that the door is
open, close the door.
• The 220V is directly connected
to the door. Check and repair
the power wire connections and
insulation state.
• Check the door switch. Replace if
faulty.
• Check the main PBA door sensing
circuit. Replace if faulty.
• Check the drain Pump wire
connection.
▶
Type1
The resistance of Nos. 3 and 5 of the DOOR LOCK
SWITCH must be approximately 1000Ω±50%.
3 5
▶
Type2
The resistance of No. 2 and 3 of the DOOR LOCK
SWITCH must be approximately 155~200Ω
( In state of pushing slider)
