Detected
- 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.
- 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.
- 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.
- The drain pump filter cover is engaged incorrectly.
- 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
error (at a narrow section), the water level detection does not
work and water is supplied continually.
- Water is supplied continually because of freezing or because
there is foreign material in the water supply valve.
- This error may occur when the water level sensor is degraded.
- The washing heater sensor in the tub has an error.
(Contact error or temperature sensor fault)
- The connector is connected incorrectly or is disconnected.
- If the water level sensor operates without water because the
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.
- As laundry causes this error, check the laundry.
- Find the reason for the unbalance and solve it as directed in
the user manual.
- This occurs when too much foaming is detected. It is also
displayed while foaming is removed. When the removal is
finished, the normal cycle proceeds.
"Sud" or "SUdS" is displayed when too much foaming is
detected and "End" is displayed when the removal of the
foaming is finished.
(This is one of the normal operations. It is an error for
preventing non-sensing faults.)
Causes Remarks
When the door is not
opened after the door
open operation.
When the door is not
locked after the door
close operation.
This error occurs
because the water
level sensor terminal is
out of place.
Heater sensor fault
: When the connector
is connected
incorrectly or has a
wire disconnected or
contact error
