Re: upper rack dishes dirty
Is it filling with enough water. Look or if you don't know how much water is supposed to be there , Just add a gallon of hot water to the machine after it fills. If this solves the problem check the filter in the fill valve or replace the valve.

Check the screen area around the sump right below the lower spray arm if it is built up with lime deposit then the wash pump is starving for water and cannot pump water to the upper spray arm this would also starve water to the drain pump.
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.)
#1 check the upper spinner arm to see if it is clogged with particles if it is, clean the holes outi f they get clogged the arm-sprayer will not clean the upper rack
#2 if it is not clogged got to your local Grc.chain and purchase a bottle of dishwasher cleaner for about 8.00 follow all instructins on bottle make sure water is hot by running hot water tap closest to dishwasher.use it in an empty dishwasher.You will be amazed how clean your dishes will come out after the first wash
maybe not... if unit is incorporating more than one spray arm,chances are the upper spray arm is not getting water.pull top rack forward,gaze under top rack near rear manifold.slowly push rack back in.notice if manifold inserts into upper wash feed.if so,possible motor issue. if not,bingo was his name-o!
Make sure you get water to the dishwasher. Check to see if the water
shut-off valve (located under the sink) is open. If you get water to
the dishwasher, but there is still no water inside during the fill
cycle, the problem might be with a faulty water valve (located at
the bottom of the dishwasher, behind the kick panel, on either
side), in which case replace the water valve.
If there is not enough water, the dishes would not get cleaned. This
could be caused by a partially closed water shut-off valve (located
under the sink), or a faulty dishwasher water valve (located at the
bottom of the dishwasher, behind the kick panel, on either side).
There is usually two, sometimes three spray arms in a dishwasher.
Make sure there is no debris blocking the holes inside each spray
Can you remove the upper spray arm (is yours under the upper rack?)-mine unscrews and then you have to wiggle it off. Run faucet water into the arm; sometimes little bits of crud get stuck in the holes that spray the water out, and this prevents a complete rinse. I just had to clear these holes myself due to same problem (I might have a different machine, though). You can do the same for the lower arm.
I had this problem twice with my Bosch and both times required different fixes but they both worked.
1. I got this one out of the manual. Make SURE that you push the upper rack totally back. There is a connection back there that fits into a fitting on the back of the rack and pushes the water through the upper arm.
2. I had taken off the extra rack that attaches to the back of the lower rack. Then I put it back on wrong. It should not have the prongs appearing behind the rack.
Both of these situations caused cloudy/dirty dishes. Also, because of the lack of water, it clogged up the filters. Remove the filters and clean them well. Then make sure you have neither of these issues going on. My dishwasher returned to great washing.
brittgee, there has been a number of service flashes on this model. One that has to do with the upper spray arm assy. Complaint is poor washability; gritty glasses, food redeposited on glasses, especially in the corners. They redesigned the upper spray arm to improve water spray to all corners of the upper rack. The new part number is 8269022. They also redesigned the third level spinner for more consistant rotation and better washability. This was also under a service flash. Part number.8193768. Other reasons for poor wash would be; low water temperature, rinse aid disp. not working, loading etc. Catriver...post back.
