Question about Dishwashers
I found the problem to be neither blockages of the upper arm or roof spray arm or the upper basket arm hitting the the back of the dishwasher. the problem was that the pump inlet where the food scraps are macerated was blocked with all manner of gunge including small chicken bones plastic and other detritus. Removal of the macerator housing under the upper filter housing using 2 different sizes of torx driver easily fixed the problem. Probably why the upper dish rack cleaning degraded overtime, Directly proportional to the amount of detritus blocking the intake screen behind the macerator.ator. See pics

I found that the end bottom angled jets of my upper arm was rubbing the pipe that enters the water feed tube at the back of the dishwasher. When you push the upper rack in and close the door, the angle created between the upper rack (which holds the upper arm) and the tube that enters the water feed tube blocks that upper arms and won't spin freely. To check if that can be the case, remove the lower rack and start your dishwasher. After the water fills up the dishwasher, let it run for a 5-10 seconds and open the door quickly. Check if the bottom angled jets of the upper arm rubs the entering pipe as the position of the upper arm will be facing the door. You can try it a few other times by moving the upper arms in another position and turn your dishwasher on again (keep the water in for faster troubleshooting - don't drain after each time). If the upper arm is still facing the door, you found your problem.
Fixing it can be difficult, but I did something that did fix it temporarily. I pulled out the upper rack and try to bend it down slowly a bit to open the angle created between the upper arm and the pipe entering the water feed tube. It's working fine for now, but will be watching it on a regular basis.

The arm rotated by water jetting thro angled jets at each end. even if other jets in arm are ok, if the end jets are blocked, the arm will not rotate. best to take the arm out and run water thro the middle hole
