LG Tromm model wm2277HS?

I just expierienced this same problem, took the top panel cover off and discovered the 3 way mixing valve that the hot water hose is attached to has 3 solenoids on it and one was the leak. took it apart and there is a black washer inside each one that needs to be replaced. going to hunt down the washer later in the week.
hope this helps you.
