LG LDS5811WW Low pressure out of spray arms
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?
Good Luck!
Brand new LG LDF6920 makes a whistling/high pitch
I had a brand new Dishwasher do that, it wasn't an LG it was a Frigidaire i think, turned out to be some bits of plastic from the manufacturing process that were in the pump. I had another one that made thumping noises and turned out to be a little piece of the tape, you know all that blue or green tape they hold everything in place with when its new. Did you run it through a few cycles and see if the noise quit? Believe it or not when i called about the one that was squealing their customer service said to run a couple cycles to remove anything that might be in the pump from manufacturing, sure enough midway through the second wash cycle it just went quiet and never made another noise again after two years.
