Water Inlet Fault

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.

It is possible that the machine does not start off the cycle because there are errors due to feedback from the inputs. For the program to start up the main program controller must initiate the INLET/MOTOR/DRAIN pump/ valve to open up and allow each function to be driven starting from the flow of water into the drum as also the drain valve to open to exit the water at the point of the program cycle. If this does not happen then the voltage at the valve/motor/pump must be checked or the fault relates to no voltage from the controller. This means the controller is a suspect.

If the water flows though the inlet then the flow pressure should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. Once the water comes into the system the WATER LEVEL SENSOR - normally a pressure switch- must activate at the preset/chosen level to give the signal to the program controller to switch on the motor. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor for rinse and wash.

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the dry spin with the drain valve/pump activated so as to drain off all the water from the clothes during the spin.

If the flow meter does not register 10 and 1/2 gallons of water in 8 minutes the FH code appears.
Could be a bad flow meter, sensor, wiring harness is loose or a bad CCU Central Control Unit.
At the RINSE cycle if water enters the machine you must time the water fill for 8 minutes or less.
If water does not enter the machine suspect the CCU as bad.
