Flash 

This may occur when 

the drain pump is 

defective. 

•  If the drain pump revolutions are 

restrained due to freezing in the 

winter season, check the method to 

remove the freezing and remove as 

directed. 

•  Check whether the revolutions of 

the drain pump motor are restrained 

by foreign material, and remove as 

directed. 

•  Check the wire connectors on Main 

PCB and Drain Pump ASSY. The 

connector or wire may have poor 

physical connection.

•  Check the drain pump resistance.

Check the drain pump resistance.
(Check whether the impeller of the drain 

pump motor are restrained by foreign 

material . 

Resistance : 13.5 ~ 16.5Ω) 

This may occur due 

to frozen water.

Check if there is 

any alien substance 

inside the draining 

pump.

This may occur when 

the main PCB is 

defective. 

Communication 

code

Warm LED 

Flash 

The signals between 

the sub and main 

PBAs are not sensed. 

•  Check the wire connections and 

terminal contacts between the sub 

and main PBAs.

•  Check for disconnected wires.
•  Check whether the sub PBA is short-

circuited because of moisture.

•  If the main PBA’s communication 

circuit is faulty, replace it.

-

Incorrect wire 

connections 

between the sub and 

main PBAs. 

Water 

Leakage code 

High

LED

Flash 

This may occur when 

an alien substance is 

in the DV Case. 

•  Since this occurs when an alien 

substance is in the Draining Bellows, 

for natural draining, remove the alien 

substance.

•  If the drain motor is defective, replace 

the motor.

•  Check if the water leaks from the tub 

connection part. 

-

This may occur due 

to a defect of the 

product’s internal 

hose or from the part 

assembly. 

Switch code

(Main Relay 

code) 

Eco Warm 

LED Flash

The Power button is 

continually pressed.
A button other than 

the Power button is 

continually pressed. 

•  Check whether either the Power 

switch or a tact switch is continually 

pressed.

•  Check whether the service PBA 

holding screws are fastened too tight. 

If they are fastened too tight, loosen 

them a little.

•  If the main PBA switching IC on/off 

code has occurred, replace the main 

PBA.

•  The “Eco Warm LED” flashes if the 

main relay connections are incorrect. 

Check the connections. If there is 

no flashing LED in the connections, 

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 code occurs after 

approx. 30 seconds has passed.
