The first thing to do is visually check to make sure the water connections from the sump assembly to the top spray arm is all in good shape and connected, also make sure the spray arms ports are clear of any foreign material. Make sure that the top rack is seating properly to the water tube in the back of the machine. If this is all good it is possible that the diverter valve is malfunctioning. If it comes down to the diverter valve I would recommend that an authorized repair company assist you as they can be a trick and quite involved.

spin the top rotary arm to make sure it spins freely also take it off to see if its blocked (run it under tap) check all other filters too and when you load dishes make sure they do not obstuct top rotary arm if none of this works then it's time for an engineer im affraid good luck

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

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...!

I know this isnt the same model, they dont carry your manual as of yet. But it does have some suggestions to look at on page 17. I had the same problem and I looked really carefully and found my sprayer arm was blocked. I cleaned it out and havent had a problem with it again. I do check it regular now.
