So I posted the other day about this LG model and determined that the water valve in the door was bad. the valve was bad. I returned today with the new valve and the water valve solenoid stays on. There is 110 volts constantly going to the water valve in the door. I suppose thats why it burnt out.
The valve in the back that goes to the filter is not energized.
If I push the water lever, then the rear filter valve is energized and water comes out.
If the lever is released, the power stays on at the water valve in the door, but not the filter valve in the back.
My assumption is that a relay on the main board is stuck, sending constant power to the valve in the door.
Any help is once again appreciated.
