My LG washer WT1201CW does not stop filling with water until it overflows

SOURCE: LG WFT1022TP top loader washing machine

the system which controls water level is an air chamber with a small diameter pipe which goes to a pressure stat. when the correct level is reached, the pressure in the air chamber switches the pressure stat and cuts the water off. the things to look for are: gunge in the air chamber split in the pipe. faulty pressure stat to test, get a similiar length of small diameter pipe and connect it to the pressure stat instead. with the machine filling, blow gently into the pipe and see if the water intake cuts off

SOURCE: Washer constantly fills with hot water even when turned off.

Sounds like a bad mixing valve. To verify that it is the valve you need to turn off the washer when it is filling. If water keeps running, replace the valve, Cost is under $50. for most washers.

This is probably a control board failure, which should be replaced by someone familiar with them.
If you are handy, you can do it yourself.
If you need assistance, let me know.

Set the water level selector to a lower level. The sensor will always work if the water level is much higher than the trigger level. However, the "much higher" condition is never reached if the water is about to overflow.

if the water was overflowing from the top of the tub it sounds like the pressure hose came loose. tilt the control panel back and you will prob see the hose that connects to the left side (where you adjust the water level) has come loose. cut about 1/4 inch off of it and re-connect it.
