On the LG LDF xxxx dishwasher family, the Vario feature uses a motor/check valve to switch between "full power" cleaning from _either_ the lower or the upper spray arms, never at the same time. So, not seeing the upper arm spin during the lower arm spinning is standard operating procedure.
But back to your problem. Step one would be to remove the filter assembly again and make certain that there is nothing (debris, broken glass) blocking the white areas where the check valve rotates to switch between upper/lower spray arms. A blockage there ~could~ cause impotent spraying/cleaning.
If there is no blockage and the impeller remains in good shape, suspect a failing wash pump motor. Try to isolate the noise to that motor.
Watch for error codes on the display and report back what you find, OK?

I have an LG LDF8922ST model with the same exact problem (16 months old as well). I think you are right about the vario spray system. Seems like the repair guys that come out are clueless and get very little assistance from LG customer assistance. I will never buy another LG product again.

Hey friend, thank you for your inquiry!
You should remove the spray and clean it out with warm water to assure that no debris or dirt has clogged the arm from functioning. Additionally it could be a problem with the arm being blocked, check for any items nesting on top of one another. I hope this helps to some degree. -Matt
