Upper rack is not cleaning. Greasy dishes on top seem that dishes are not being washed. Seems the upper water turning dispenser is not working, Bottom rack seems ok. I guess I only have half a dish washer ?

could be a few things clean inside filters and screens listen to it does the wash motor during wash sound strong like it tossing water around in there open the door during the wash see if kicks some water out at you. If it sounds and seems like its working ok then some units have a rubber check valve little flapper in the tube that goes up the back wall to the upper spray arm i have seem break off and clog that tub not allowing any water to the upper spray arm.

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!

Make sure the center loading is not obstructing the water jet to the top shelf. Top shelf is only for glasses and saucers , use Jet-Dry .Pre rinse and clean bottom pan strainer from dirt debris.

Possible that the motor impeller has good particles in it, causing poor water pressure, which would be most evident on the top rack. You would have to remove the spray arm, then the filter, then the torx screws to get at impeller....unfortunately, that model of dishwasher isn't the greatest in the first place for washing, since it only has the one spray arm.

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!

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 Regards Gizokieth

possibly low water pressure...

racks might be in backwards if it's an older model with wheels on shelf system... rubber bumpers should face out...

could be a blockage in the upper sprayer arm... or the upper arm had come off and was remounted in a position that doesn't line up with the jet of water from below...

could be bad loading technique... sounds simple enough but you should never put large bowls or pots that lay horizontally on the lower rack because it really screws up the cleaning effectiveness. Large items should always go on the top rack or be washed by hand if they don't fit on the top rack.

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,

check water level in machine
may be not filling enough and the wash pump is starved from water thus not pushing water to upper arm
drain water from machine dismantle and clean out air tube to pressure switch take off air tube at pressure switch and blow back into sump then pinch air tube with fingers to stop air from flowing back up tube then refit to p/s
run and see if that solves problem

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.
