2 year old LG washer high pitch sound during fill

New LG washing machine has a whistling sound or whine when filling with water.
The noise was not there, but I had to do some work in the back with the drain hose. While I was back there I swapped out the cold and water supply lines and I swapped out the water arrestors that started failing.
I never had the wall valve all the way open either, so I opened that all the way up to full open. Rather than 85% open. I had folks recommend leaving that valve at 100% open not having it slightly closed as I always do.
Now I hear the high pitch sound on fill.
I ca try to turn the wall valve to slightly shut, and I can see if there is any clog in the washing machine valve, like a screen or something? This sound makes me assume there is a flow restriction of some sort?
Thoughts?

My first guess is that it's just hitting the magical flow velocity to make something resonate/sing. Try partially closing the wall shutoff valve when the machine is filling. Just search for a valve position without the sound if the sound bothers you. Leaving it full open could allow the machine to fill faster though.
