I was able to unscrew the two water intake pipes and noticed that the hot water had sand against the plastic filter. When removing the plastic filter, fortunately the manufacturer (LG) also has a finer mesh that also trapped some of the sand. It didn't appear there was enough sand to completely clog the line, but there was definitely enough to impede it and likely set off the warning.
I cleaned both the plastic piece and mesh, reinstalled, and have since run a couple of loads with no issue. I figured due to both the dual filtration and the fine mesh at the intake, any grains that their way into the unit were small enough to be discharged through the sprayers and likely out with the greywater.
Fingers crossed we're in the clear now. The folks at Mike Scott plumbing were very helpful and mentioned that the installed (Home Depot in our case) should have run the water through the lines for several minutes before connecting. To me, that's didn't seem necessary as one wouldn't expect sand in plumbing.
