Replace the
SENSOR SWITCH
ASSEMBLY.

When pressing WASH/RINSE and SOIL LEVEL at
the same time after draining, is  the water level
frequency 255?  
When pressing WASH/RINSE and SOIL LEVEL
buttons at the same time while washing, is the water
level frequency between 230 - 243 ?

Replace the MAIN PWB
ASSEMBLY.

Check the voltage between two pins while pressing
the POWER button. Is the voltage 220-240 V AC?

Repair the DRAIN HOSE
ASSEMBLY.

Is the drain hose twisted or frozen?

Remove foreign material.

Is the impeller of the drain pump clogged?

Reconnect or repair the
connector

Is the connector disconnected, disassembled?

Replace the DRAIN
PUMP ASSEMBLY.

Is the coil of the drain pump too high or low? 
(resistance of the coil is 10-20 1)

Replace the MAIN PWB
ASSEMBLY.

When checking voltage between connectors during
spin, is the voltage 120 V AC as in the figure? 

9-1. FILTER ASSEMBLY (LINE FILTER)

9. COMPONENT TESTING INFORMATION
