Check
Mode
- A switch contact check because of a deformation of the door
hook.
- When the door is pulled by force.
DC
- This occurs in the Boil wash because the door is pushed due
to a pressure difference from internal temperature changes.
- The door lock switch terminal is connected incorrectly.
- The door lock switch terminal is broken.
DC1
- This occurs intermittently because of an electric wire leakage
- Main PCB fault.
- This occurs if the Power switch is turned on/off
DC2 continually and too much heat is generated (This
check is difficult to be reproduced.)
- The washing heater is short-circuited or has a wire
disconnected.
- The washing heater in the tub has a check.
(Contact check, temperature sensor fault)
HC
- If the water level sensor operates without water because water
HC1
is frozen or for any other reason and the temperature sensor
HC2
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.
- The drying heater is short-circuited or has a wire disconnected
- Heater engagement fault. (out of place)
- The air hose is out of place and water leakage occurs during
the spin cycle.
- The tub back at the safety bolts fixing part is broken.
- Water leakage occurs at the front with foaming because of too
much detergent.
- Water leakage occurs because the connecting hose to the
detergent drawer is connected incorrectly.
LC
- The drain pump filter cover is engaged incorrectly.
LC1
- Water leakage occurs at the drain hose.
- The duct condensing holding screws are worn.
- The nozzle-diaphragm is engaged in the opposite direction or
the rubber packaging is omitted.
- Water leakage occurs because the screws that hold the tub
back and front in place are fastened incorrectly.
- The leakage sensor is faulty
- Water is supplied continually because the water level detection
does not work.
- Because the drain hose is clogged and there is an injection
check (at a narrow section), the water level detection does not
work and water is supplied continually.
OC
- Water is supplied continually because of freezing or because
there is foreign material in the water supply valve.
- This check may occur when the water level sensor is
degraded.
Causes Remarks
When the door is not
opened after the door
open operation.
When the door is not
locked after the door
close operation.
If the heater has no
check, this occurs
because of a PBA relay
malfunction.
This check occurs
because the water
level sensor terminal is
out of place.
