Question about LG 24 in. LDS 5811ST Stainless Steel Built-in Dishwasher
Dishes are not getting clean. Low water pressure coming out of spray arms. Arms do not rotate. Water spray out of lower arm holes is about 4 to 5 inches high with no rotation. Screens clean. Nothing in impeller. All arm holes clear. Water pump turns by hand. Water drips from nut that holds upper arm in place. No water spray from upper arm. Upper arm does not rotate. Noise that sounds like something draging on impeller for a few seconds, then goes away. Happens three or four times at start of each wash cycle. Sound like something starts to rotate, then stops. Whats wrong? Thanks for your time and help!
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 would start with watching the operations of the dishwasher if you can before trying my fix. start with a few sandwich bags and flashlights. I had a small video camera to record the operations of the dishwater so I know whats wrong. My upper arm didn't spin as it had little water coming out causing my dishes to be dirty.
This is a easy fix for any dishwasher with this problem. Remove all the screws on the lower pump assembly. underneath you will see two white wheels. The taller white wheel is what changes the water flow. I believe it only turns one direction so rotate this until the closed part is against the wall thus opening both ports. This wheel is what controls the water flow for both lower and upper sprayers. Reassemble the cover carefully with the gasket in place.
This job is really easy to do so just take your time.
Moving forward I wouldnt use the half load option on your dishwasher as this might cause this problem again.
Hope this helps fix your dishwasher.
