Why does my lg washer not stop filling with water?

Unplug the washer removing all electrical power from the machine. Turn the water back on and confirm that water is still entering the machine.

If the condition is true no power to washer and water enters machine it is very likely that the fill solenoid has failed.

this part is not that difficult to replace.
Water Inlet Valve part 5220FR2008F LG Washer Repair

HI,

From your description, it sounds like there may be a problem with the inlet water solenoid valve(s). They can stick after several years of use. The se valves are located in the machine, just inside where you connect the water hoses.

Bad water valve or main board. the water valve closes when it stops receiving voltage from main board. If it's not closing then valve is bad.

if it fails to stop running only at the rinse part of the cycle it is probably in the timer as the solenoid valve has to cut the water off when the washer fills for the wash cycle too. fills for wash cycle and cuts off water, washes and drains, refills for rinse cycle and water just keeps running? does this every time you run it? that's in the timer. bad solenoid (water inlet valve) would keep running even on wash fill up. hope this helps.

Are you using HE soap?

When you blew into the tubing, you destroyed the water level sensor. You will need to change the water level sensor to stop the unit from over filling. That part number is 6601ER1006E. As for the LE error code, you one of 2 things go bad. Either the motor sensor has failed or the control board has failed. Chances are the motor sensor has failed and is the cheaper part to replace. The part number for that is 6501KW2002A
Good luck

Hi from retired Englishman in SW France,
This is symptomatic of a malfunctioning (not closing completely) water control valve- the hot water one, if the washer is hot and cold fill, and the cold one if it is just cold fill!
Sorry but it needs replacing and a service call ;-0(
Good luck,

Try adjusting the water lvl going into the washer. Adjust accordingly. If you have a meter, just the resistance of the valves. Unplug of course. It should read about 1.4k ohms ish. Could be higher or lower but roughly that.

If water runs in when the machine is OFF but stops when the tap is turned off it means a faulty watervalve.replace water valve. Probably a double valve. Dont mix up the hoses or the wires........Nomess
