LED  

                             

Drain Error 

 nd                                

Check for Foreign material entering the pump or hoses.  

Check to make sure the wiring harness is connected properly. 

Check the water pump terminal . 

Check for freezing. 

The water level fails to drop below the Reset Water Level

 

  within 30 minutes. 

                         

Power Error  

   2E             

Make sure to check the operating voltage. (An error occurs when 
under or over voltage is supplied.)   Check whether a plug recepta-
cle is used. When the connecting wires are too small (extension 
cord use), a momentary low voltage may drop up to 10 V 

Main PBA fault (sometimes) 

PF  

Momentary Power Failure 

                                 

Communica-

tion Error 

AE  

Check the wire connections and terminal contacts between the sub 
and main PBAs. 

Check for disconnected wires. 

Check whether the sub PCB is short circuited because of moisture. 
If the main PCB’s communication circuit is faulty, replace it. 

                              

Switch Error 

(Main Relay 

Error)  

  E2             

Check whether either the Power switch or a tact switch (any button)  
is stuck down. 

Check whether the service PBA holding screws are fastened too 
tight pinching the contacts 

If the main PBA switching IC on/off error has occurred, replace the 
main PBA. 

The “E2” error occurs if the main relay connections are incorrect. 
Check the connections. If there is no error in the connections, re-
place the main PBA  

  SR  

Door Error 

ds          

(Before 

operation)  

 

 

 

Check the door switch and latch alignment .  

Check the latch for damage 

Check the wiring harness to the latch.  

Check the door switch. Replace if faulty. 

Check the main PBA door sensing circuit. Replace if faulty. 

Finally verify he operation of the Main PCB
