Dishwaher does not clean, upper rack

\015 Whirlpool Dishwasher Mod DU1145XTPQ7, won't clean dishes placed in upper rack. Lower rack cleans acceptably. Is there possible a clogged water line?\015

Answers :

The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm.
Assuming\015\012the top spray arms are clear of debris, remove the lower spray arm to\015\012access the wash motor. Remove the 4 torx screws and the filter\015\012(accumulator assembly). Remove the torx screw and the inlet protector\015\012that covers the chopper assembly. Make sure the chopper is not broken\015\012(broken chopper will fill with debris and block water flow). While\015\012holding the chopper blade, reach inside the "D" shaped opening on top\015\012of the motor and spin the wheel/motor by hand in each direction to make\015\012sure either the chopper gear or the motor gear that drives the chopper\015\012is not broken. Replace the chopper if necessary (part # 8268383). If\015\012the motor gear is broken, replace the sump and motor assembly (part #\015\0128535150). Remove any debris from the sump area in the process.
You\015\012don't have to shut the power off to the dishwasher because the door will be open, but if you feel more\015\012comfortable, do so.
Good luck!

My Kitchen Aid KUDS01DJSS0 seems to have water going to the upper spray arm (I see water coming out of the unit just beneath the upper rack), but the pressure doesn't seem to be high enough to clean the upper rack. No evidence that water is coming out of the spray arm on the very top. Lower rack dishes seem to clean OK. I have already removed the whole upper spray arm assembly and inspected the flapper valves that the middle sprayer goes into. I suspect that it's not making good enough contac

The dishes in my dishwasher are not getting clean, particularly on the upper rack. It seems to be because the upper water arms are not spinning during the wash cycle. The bottom spin arm is working fine. I have cleaned out both upper arms as best as I could without removing them (above and attached below to the upper rack), as it does not appear that these arms are easily detachable. I am thinking maybe water is not making it up the line to the upper arms? I also have a lot of dirt in the b

My LG dishwasher upper rack has stopped cleaning. The uppermost arm is seemingly getting no water at all and the arm on the underside of the upper rack is getting some water, but not enough to turn it. I have already disassembled and cleaned all the way down to the diverter assembly and it has not fixed the problem. I think this is a problem with a the (?) diverter pump or perhaps a sensor that sends water to the upper arms. I am trying to figure out how to further diagnose the problems. The

Top rack not coming clean. It looks like the water pipe that carries water up to the upper spray nozzles has 2 big holes in it. One I can see to recieve the top rack nozzle when the rack is slide into place, but should the other one be covered to prevent all the water from dumping out before getting to the upper nozzles?

I have a Whirlpool Gold Quiet Partner III that is 8 years old and recently stopped cleaning top rack dishes. I remember finding a mylar like piece in the bottom of the tub and threw it away thinking it came off of something we washed (I know, bad thinking.) The mylar piece measured roughly 3-4inx2in and was folded in half. Anyways....the upper arm does not spin and the detergent doesnt get fully dispensed so dishes dont get fully cleaned.
