The chopper blade assembly with in the pump housing is either clogged or broken, to get to it, you must remove spray arm and remove screws from filter housing. These are size 20 torx, inside sump are 2 more screws size 15 torx, after these are removed you can clean out chopper or replace it.

If the dishwasher won't clean dishes, check the lower wash arm assembly. If the lower wash arm isn't getting water, all of the dishes in the lower rack will come out dirty. Check to be sure the lower wash arm assembly spins freely. Also check to be sure the little holes in the lower wash arm aren't clogged or blocked.
I had the same problem I own a Kenmore Elite dishwasher. Diverter motor needs to be replaced. The diverter motor is connected to a plate that controls the flow of water to each washer arm. When the plate moves it has holes that align to the proper tube that supplies water to a washer arm. When the diverter motor is broken it is unable to rotate and cannot direct flow of water. When this happens water will only be able to come out of one spray arm in my case the back sprayer or turbo wash. The diverter motor is located under the dish washer and the diverter plate is located under the bottom sprayer arm.
Your sprayer arms may be clogged. The upper arm attaches to a tube in the back of the dishwasher. If the support clamps come loose, the upper spray tube will not be flush with the tube and can't carry water to the sprayer arms. Also the sprayer arms can become clogged with paper remnants, bone fragments, or pieces of peeling. You'll need to remove the sprayer arm and flush it at your sink. If there is a jet that is clogged, tweezers will help remove the residue. Finally, the bottom of the door INSIDE the washer often get covered with gunk. Be sure and gently wash the bottom of the door INSIDE. You can open the door, spray some window cleaner on the bottom and then gently brush away the 'gunk.' Rinse with hot water from a pitcher or your sink sprayer and this can eliminate some of the residue that is showing on your dishes. I hope this helps.

These spray arm will only get water several times in the wash and rinse cycle.They do not turn at the same time the lower (bottom large spray arm under the bottom rack).
There is a chamber that diverts water either to the bottom sprayer or to the top sprayers, not to both at the same time.
If your top spray arms never get water, then there must be an issue with that chamber motor to divert the water. A new sump assembly that has all the new parts.
Sprayers require water to pass through the jets to provide motion to the arms.
Remove the sprayer from the machine and look for blockages. (Removal should be easy, at it is expected that the user will need to clean the jets occasionally; If you have any problems removing it, consult your manual).
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?
Open the dishwasher, remove the bottom rack, then remove the thumb nut in the middle of the unit that secures the lower wash arm and housing. Look for debris and clear any you find. Try again. If no joy, you will have to repeat the first step and also remove the wash pump upper housing that is secured with torx head screws. Same thing after you remove it - look for debris in the impeller area and remove it.
If you have to remove the wash impeller, you will need a 1" offset box wrench and as I recall a 1/4" socket. The 1" offset box wrench is needed to keep the impeller from turning while you remove the center nut. You will also need to remove the upper discharge line retainer clip to get that out of your way. Inspect the impeller for any debris and especially cracks or missing blades. If the impeller is damaged it will need to be replaced.
While you have this thing apart, check the lower wash arm and upper wash arm discharge pipe assembling for any obstructions.
I am assuming the motor runs ok and the timing cycles seem normal.
The strainer is located directly under the lower sprayer arm. When the strainer becomes clogged with food and detergent debris, the dishwasher may flood or overfill. On some dishwashers, the strainer is a plastic or metal component consisting of two semicircular halves. To remove this type of strainer, pry it up. On other dishwashers, the strainer is a one-piece component. To remove this type, remove the cap that holds the sprayer arm on its shaft. Then remove the sprayer arm and the strainer.
Wash the strainer in the kitchen sink with water and a mild household detergent. Use a fairly stiff brush to get all the debris out of the holes and slots in the strainer. Rinse the strainer well and replace it. If part of the strainer lifts out for regular cleaning, check it and clean it -- if necessary -- after each load of dishes is washed.
The pump in the dishwasher is supposed to provide enough water pressure to turn the spray arms and make them rotate. The pump is faulty and not giving enough pressure or the arms are stuck. Try spinning the arms, if they rotate smoothly, you will need to replace the pump.
