I'm getting an OE error on my LG washer diplay

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.)

I hope this helps.

Keeping in mind that the soap & bleach gets dispensed into your wash on the second to last rinse cycle and that most all rinse cycles are in cold water. Is your cold water valve screen plugged causing your washer to rinse poorly? Are you using the HE detergent? If not maybe the washer is sudsing up to much and having a hard time rinsing all the suds and bleach out and leaving the clothes soapy.

Fill the washer up with no clothes in it on a cold/cold wash setting does it take a long time to fill the washer up? Also when it is full and agitating is there suds in the washer?

Last suggestion is if the drain is hose is a lot higher than the top of the washer it might have a hard time draining out all of the soap water before the next load

if you go to spin only cycle, does it drain and then spin? if yes, then most likely control board.

i believe if the water outlet is still good,,,,,u will have to loose out the pump from its cup , mayce something hooked its propeller inside the i cup or replace the water pump

OE is normally down to blocked drain pipes, mcalpine (connection under the sink) or a blocked front filter. empty the machine and unscrew the filter behind the flap at the bottom right hand side, check for any obstructions, icoins, hair grips etc are normally blocking here

Broken or has come off. Drive belt

Check and see what type detergent you are using. I bought regular liquid detergent and the machine began making noise during the spin cycle and the drum would not spin. I was informed that you have to use detergent that is labeled HE (High Efficiency). The regular liquid detergent will suds up during the wash cycle which then causes the drum to slip and not spin during the spin cycle. What you are hearing during the spin cycle is the drum slipping. Unplug your washer for 30 minutes and let it reset. This lets the suds dry out. Run a cycle with no spin to rinse out the drum. This should eliminate your problem. If you have clothes in the machine, run a cycle with no spin, just don’t add any more detergent. Then run the normal cycle with spin a second time with no detergent. I hope this cures your problem.
