Cold water continues to run during entire wash cycle
The washing machine fills as should; but when it kicks the water off, the cold water still runs even at a trickle. If you are not carefull it can overflow the tub if you are using an ex-large load..when the cycle is completely finished the cold water shuts off after the spin cycle but it does take alittle time for it to completely stop...not for sure if we need a new switch or inlet valve or something else....thanks for any help at all.

Re: cold water continues to run during entire wash cycle
Adrea, sounds like you need a new valve. When it's doing this leaking, unplug the washer. If it's still leaking you know for sure it's the valve. Part number for the model posted is 22002360. Catriver..post back.

Sears Parts Direct is one source of the parts diagrams, https://www.searspartsdirect.com/model/1vc37q1bdj-003204/lg-wm3987hw-washer-parts . See the Dispenser assembly parts diagram for the water inlet valve. If you can watch the entire cycle, try turning off the shut-off valves for the washer inlet hoses after the rinse cycle and before the dry cycle starts. Water should not flow into the washer/dryer with the shut-offs closed.
I've seen inlet valve solenoids fail in the open position or in the closed position. I've never seen a control board that sent open messages randomly. (Sometimes, there is damage to the control board or corrosion or damaged wiring that stops the control board from sending the open/closed message to the solenoid.)
usually the wash is a mix of hot and cold and the rinse is just cold, that said, it is most likely a problem with the cold water supply. check to make sure the cold water valve is all the way open and the hose isn't kinked. If those are ok turn the water supply off and remove the supply lines on the machine side, you will see a screen inside the washer that may be clogged with sediment. If so, just clean it out and put it back together. You may also want to run a wash cycle on cold only to see if it fills slowly for the wash cycle. If it does fill slowly on cold you have low pressure on the cold side.
the timer, if your washing machine fills with water and begins
agitating, but the timer never advances--or if the washer is in a spin
cycle and the timer won't advance. Then you need to replace the timer.
may be a cold-water supply problem, if the washing machine fills with
water, agitates, drains, and spins, but then doesn't fill with rinse
water. See There's no cold water.
