The dishes began two weeks ago not cleaning properly with deposits left inside the glasses and cups on the upper rack. I checked the lower spray arm and found I can spin it manually but the wash cycle will not spin it. I saw that water is shooting out the holes, just no rotation. There are no obstructions to the arm.

Re: lower arm won't spin
The arm only rotates with water shooting out of the angled jets at the end of the arm and these are probably blocked ( i assume it is free to totate manually)
take the arm out and run water into the centre hole and this will help push whatever is blocking it to a visible position - usually rice or sweetcorn. you say there are no obstructions in arm but when no water flowing, the blockage tends to slump back into the main body of the arm and out of sight

Make sure that that upper arm is free to turn. Check it while you have dished installed, because sometimes, dishes on the lower rack may stick up too high and hit it. Otherwise, check the back of the water-supply tube attached to that upper rack.... Is it lining up with the water feed port or hole at the backof the dishwasher? Is there a gasket that is either ripped or missing? And check that wash arm carefully.... Might it be split or bent? Are the holes on the bottom clear? (Those holes are usually angled to push the arm around; if they are clogged, the arm won't rotate.)
Hello, check the sprayer arm on the top of the dishwasher inside and to see if it spins. Don't block this spray arm with glasses or dishes that could block the operation of this sprayer cleaning arm.
Now, if it not spinning, check out the fitting arount hing bolt. If this wore out then you will have water pressure lose. Replace if need be. Also, check the feeder water spout that runs the upper spray army, it could be pluged. GB...stewbsion
Probably a blocked spray arm (part that spins around). Remove each of the spray arms and check and clean all the holes as this is where the water sprays out from to clean the dishes and glasses. When they are blocked you get poor wash results. Hope this helps
With the LG LDF6810 model, this is not a common problem.
Please try the following test, With and empty dishwasher, add a small to normal amount of dry dishwasher powder and run an (empty) load.
Check to see if any soap remains in the dispenser cup.
If any remains, here are three things to do:
1.) Upgrade your dishwasher detergent to a name brand powder (e.g.: Electrosol or Cascade)
2.) When you load the dishwasher, do not place large items in the front, near the door/soap dispenser.
3.) Before you load the dirty dishes for the next several loads, with your hand, turn both the upper and lower wash arms so they point at the door. Load as you normally do and push the racks fully in. Before you close the door, spin both the upper and lower arms and confirm that they spin freely and neither hits anything. if either does not spin freely, pull out the rack and arrange so the arms can spin freely.
I find that the only time I have left over detergent powder is when the wash arms do not spin freely.
This is a common problem on most every energy star/water conserving dishwashers.
Please report back what you find, OK?
try c.l.r. to clean dishwasher check and clean lower and upper spray arms out, run no detergent you can also run vinegar in it as well about a cup full,let the machine start to run then stop dish washer for a few hours then restart see if this works for you use a short cycle.
ok so If your dishwasher has worked fine in the past but, suddenly, your
dishes aren't clean after the dishwasher completes all cycles: 1) Check your water heater's temperature dial to
be sure it hasn't been changed recently. 2) Be sure dishes haven't prevented the detergent
dispenser from opening properly during the wash cycles or kept the spray arms
from turning, the lower arm from rising, or the spray from reaching the upper
rack's dishes. 3) During the wash cycle, listen to the spray arm
spinning inside. If it seems to be spinning poorly, clean out the spray holes
in the spray arm(s) with a stiff piece of wire; wait for the machine to cool,
and then remove the spray arm(s) by unscrewing the hub cap and lifting the
arm(s) off RegardsGizokieth
Check the upper arm for free spinning, then remove the arm and check that the seam between the upper and lower halves has not split somewhere. Also check all the small holes for debris plugging. Run the machine in wash cycle for a little while with the upper arm off--that should flush out anything blocking the pipe up to the arm. If still nothing from the upper arm, tear down the lower arm assembly down to the deck while noting position of all parts removed. Clean the big screen at the bottom in white vinegar and hot water. Inspect the holes in the bottom for anything blocking them.
Had similar problem with our Maytag dishwasher--we removed all spray and screen components to the inner case, cleaned the intake screen below the lower spray arm, repaired a split upper spray arm, and inspected everything for cracks or other distortion. All of this helped some, but finally improved things by changing from liquid detergent to a "packet" type. Our water is somewhat hard and builds deposits on the screen at the bottom. Run a no-dish cycle with a cup of white vinegar in the bottom.
Almost all of the problems mentioned above will be solved by having the owner buy a name brand detergent powder (like Electrosol or Cascade) and using a little less than you think you should.
For those who continue to have problems with poor cleaning, you need to remove the lower spray arm (pull straight up firmly, then out) and then remove the 9 screws that hold the filter in. Using a flashlight, inspect everywhere in the sump area (be careful of broken glass!) Remove all debris and especially look for something blocking the white check valve that is driven by the Vario motor to control the alternation between the upper sprayer arms and the lower arm. Reasemble and test.
If inside dishwasher is a mess with white mineral deposits, recommend you place a bowl filled with white vinegar on the rack of your empty DW. Start a quick cycle with no detergent added.
Check out how clean it is when you are done!
If you have problems after this, please post back what you are seeing.
id try removing hte lower filter plate . 5 torx 15 screws will gain oyou acess to lower sump and 2 more torx screws that will acess you the chopper assy, prhaps filled with debris not allowing good water flow,
