I have a brand new (Dec 1st 2006) Kitchen Aide KUDP02CRBL2 and the glasses on top shelf are not getting clean. Center arm is free but turns very very slowly. Sears repairman checked all tubing and jet holes and all were wide open. We then tried to catch the center arm rotating by yanking open the door while running but we could not discern any rotation; however the arm might have moved about 45 degrees in 30 seconds. Repairman then told me that that is how it was designed. I don't believe him. If I yank the door open really fast while the dishwasher is running I might catch the middle arm moving about an inch or two before it stops. I think I should see it move at least 90 to 180 degrees before it stops with at least some water spewing out.
Do I have a case for getting a new pump? or repair/replacement of unit?

Re: top shelf not cleaning
Kenp, did the repairman check the screen where the chopper is located? If this screen becomes clogged with gunk, water will be restricted going to the center arm and you will either have slow or no roatation. He would of had to remove the lower spray arm, filter and accumulator assy. to get to this. I had one the other day with the exact same problem and the chopper screen was plugged completely. If your dishwasher is not working right, you have 1 year warranty, parts and labor. You have a case for them to come back. Catriver...post back

Make sure to clean it the best you can and they have my types of cleaning products available and run one or two through depending on water type or dirty ness of machine fire this should clean for better water flow and the spay arms should distribute water better that's getting your upper and lower shelves in your dishwasher cleaner and your dishes squeaky clean
Check your upper wash arm.... check the holes, especially the ones at the end of the arm. Are they possibly clogged with debris or hard water? This is the usual cause of dishes on the top rack not getting clean. The holes at the end of the wash arm are angled to eject the water at an angle to use the reaction to push the wash arm around. If those holes are clogged, then the arm won't rotate, and only those few dishes or glasses right under the arm will get clean, and the remaining 80% of the dishes on the upper rack won't get clean!
Check the center wash arm assembly. If the center wash arm isn't getting water, all of the dishes in the upper rack will come out dirty. Check to be sure the center wash arm assembly is mating properly with the water supply nozzle in the back of the dishwasher. Also check to be sure the little holes in the center wash arm aren't clogged or blocked.

There is a pipe/tube that runs up the back of the inside of your dishwasher. This provides water for the top spray arm. The spray arm has a feeder tube that covers the pipe in the back. If for some reason the feeder tube has come dislodged, the water just drips back down into the dishwasher, never touching your upper shelf. My kids used to jam cutting boards and other large items into the lower shelf and in so doing, would dislodge the upper spray arm feeder tube. Just pull out the upper shelf and check to see that the tube is in the correct position. This should solve the problem. If not, then the spray arm may have debris in it that keeps the water from being forced through the jets. You'll need to flush the arm with the spray attachment on your kitchen sink. I sometimes use tweezers or a toothpick to dislodge bits of peelings, paper, or bone that manage to get into the sprayer arm. I hope one of these tips helps. If it does,please come back to fixya and rate my answer.
I have an older dishwasher also and recently my wife also complained about it not cleaning right... so me being the man I am tried in vain to clean the things... Bought new spray arms online and installed them in minutes...now the thing works like new... However I have also found that if the heating element goes bad then that also can mess things up bad... So I would buy new spray arms, and also check out the heating element to make sure it is working... Here is a tip that will help you with the online buying... Dishwasher Spray Arms not Spinning
Probably a blocked spray arm. Remove the top spray arm 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. Might also be worth checking the other 2 spray arms at the same time.
the chopper sceen gets pluged and wont pump good.it's kinda ticky to get to you will need #15 torx bit to remove grab center of the spray arm and twist til arm will lift out, the tube going from center to back twists clockwise careful not to break it, take all the screws out of cover and take it out. in the sump tward front left down in bottom is 1 more screw if you have a wet vac or turkey baster to get water out to see it. it holds down a half round lift straight up you will see the screen clean it out and put everthing back
The broken bottom arm is probably preventing any water / water under pressure to get to the upper arm.
After you replace the lower arm, you should have much better cleaning in the top shelf.
While you are in there replacing the lower arm, recommend you remove the filter under it and clean the filter and any debris you find. Be careful of broken glass!
