Either the pump is not able to pump due to clogged pump or there is not enough water in the tub after filling to get up to the upper spray arm.

Top dish rack dishes don't get clean model 8575637


Most dishwashers have a rotating spray bar underneath the upper rack. Over time bits of food can clog up the holes and then dishes won't get clean in the upper rack. Check to make sure all the holes in the spray bar are clear and that it is rotating freely.

Water is not spraying on top rack


Assuming the rotating assembly comes out when you slide out the top rack:
Verify the nozzle mates correctly when the top rack is slid back in
Verify the holes in the rotating assembly are clear and open
You can remove the rotating assembly and pour some water into the nozzle to see if water comes out of the holes in the rotating assembly. Perhaps you have something plugging the nozzle.
If the holes are plugged, there is a product that you can put into the dishwasher to clean it - Home Depot, Lowes, Menards, and many grocery stores here in the states sell the stuff.

Top level rack pots are not cleaned, spray head does not rotate but water coming out of sprayhead, no obstruting parts


Check and see whether it freely rotates, when turned manually. The spray arm rotates under water pressure from the pump inside the machine.

Check inlet water pressure and clean the strainer at the inlet hose end near th inlet to the machine. Check and clean the spray arm axle housing also

Dishes not clean. Lower spray arm possibly not moving.


Remove the lower basket so you can access the lower arm.

Does it spin freely? If not, remove and clean the rotating point. Make sure the spray nozzles are not clogged and there as no chunks of stuff inside the spray arm.

Kenmore Elite Ultra Wash Dishwasher - top rack arm not spinning


Hi: I just posted a similar problem, but found a solution. After taking the arm, etc. apart (and verifying no blockages), I thought maybe the lack of water pressure was being caused by the fact that there are TWO holes for the top spray arm (higher and lower rack setting) on my model. ie. that water was being forced out of both holes, causing a drop in water pressure, which was causing the top spray arm to stop spinning. I plugged the unused hole with a wine bottle cork (to keep the water from spraying out the unused hole), and voila, it now works.

I wish all appliance fixes were this easy...!

Top rack not cleaning


Some dishwashers have a telescoping nozzle in the center on the bottom. If this is blocked by a large pot in the middle of the bottom tray, the nozzle will only extend up into the pot, and not be able to spray the entire top rack.

Also, some models have an arm mounted in the top. Check and see if it can spin freely, and if it's nozzles are clogged.

De-clog by soaking the part in vinegar.

I replaced the spray arm seal, but the arm still wont spin. I get water but not enough pressure to turn the top arm. The bottom arm works fine. Should the top arm turn easily when pushed by hand. It...


arms should turn freely. spray arms are only rotated by water spraying out from angled jets at end. check for blockage in spray arms - sweet corn and rice are the worst offenders. take spray arms off and run water in centre hole and see it runs out of all the jets freely

Water not going through spray arms


1.does motor run? no. replace motor. 2.open door and leave the bottom rack inside dw.spin the spray arm underneath the bottom rack by hand. it should spin freely without binding. if it doesnt spin freely take out the bottom rack and try again. if it does spin freely then your bottom rack is laying on your sprayarm preventing it from rotating. 3.you could also not be getting enough water into your dw.
