Error Type

For USA

Causes

Remarks

Water Level 

Sensor

1C

-  The part of the hose where the water level sensor is located is 

damaged (punctured). 

-  The hose is clogged with foreign material.
-  The hose is folded.
-  Too much lubricant has been applied to the insertion part of the 

air hose. 

-  Hose engagement error. (disengaged)
-  Part fault. (Faulty internal soldering)
-  The water level sensor terminal is disengaged.
-  Main PBA fault.

Motor Driving 

Error and Hall 

Sensor Error

3C

-  The PBA connector terminal is not connected.
-  The motor spin net is not engaged.
-  The motor’s internal coil is damaged. (short-circuited or cut)
-  The hall sensor terminal is not connected.
-  Foreign material (a screw) has entered the motor.
-  Motor overloaded due to too much laundry. (Non-sensing)
-  The motor hall sensor terminal is not connected.
-  PBA fault.
-  The motor driving error from the PBA is weak.

Unstable relay operation, etc.

-  This occurs due to erroneous operating signals from the motor 

hall sensor.    

-  The IPM terminal of the main PBA is not connected.
-  The DD motor cover is out of place.
-  The PCB housing terminal is not connected.
-  PBA fault.
-  DD motor fault.

This error occurs 

because of restrained 

revolutions.

 

 

This error occurs when 

an interference is 

generated due to too 

much laundry, etc. 

Water Supply 

Error

4C

-  Foreign material is entering the water supply valve.
-  The water supply valve terminal is not connected. 

 

(Wire disconnected)

-  The warm water and rinse connectors are wrongly connected 

to each other.

-  This occurs if the PCB terminal from the drain hose to the 

detergent drawer is not connected. Check whether the 

transparent hose is folded or torn.

4C2

-  The cold and warm water supply hoses are wrongly engaged 

into each other.

-  The water temperature is sensed as higher than 50 ˚C in the 

Wool or Lingerie courses.

Drain Error

5C

-  The pump motor impeller is damaged internally.
-  The wrong voltage is supplied to the parts.
-  Part fault.
-  This occurs due to freezing in the winter season.
-  The drain hose is clogged. (Injection error, foreign material) 
-  Clogged with foreign material.
-  The water pump terminal is not connected: rubber band, bills, 

cotton, hair pins, coins have collected inside the drain pump 

ASSY. 

Power Error

9C1,9C2

-  Check the consumer’s power conditions.

:  Make sure to check the operating voltage. Connect a tester 

to the internal power terminals during the Boil  operations 

and observe the washing machine’s operation carefully.

:  Check the voltages. 

 

(An error occurs when under or over voltage is supplied.)

:  Check whether a plug receptacle is used. 

 

When the connecting wire is 1m, a momentary low voltage 

may drop up to 10 V

-  Main PBA fault (sometimes)
