LG refridgeator- Water Dispenser

I have a LG fridge model number LFX25971ST. The water in the door dispenser quite working. The ice maker still works.
It worked off and on for a few months then finally quit for good. When pressing the button you can hear it click and try to pump but no water comes out. I replaced the filter but it dident help. I think I may need a water valve or solenoid? I found the part number AP4443785 for the solenoid and three different water valves for the same model. Part Numbers AP4441311 and AP4639308 and AP4451762.
What part do you reccomend I try first? Also can you send me a drawing of where it’s located?
Thank you very much !

Did you ever fix the problem. My same model refridgerator is doing the same thing. We just bought a new filter as well. If you did can you tell me what exactly you did to fix it please? Thank you.

Nope, no one ever got back to me.
