the only way you can tell if the upper rack is not getting enough water is to turn a glass right side up in each corner. then run for 2 minutes and see if there is water in each cup.
if you still dont get water, then you have checked the pump, the only thing left is that you are not getting enough water into the unit.
start the d/w at a normal cycle, let it fill and go into the wash cycle, takes about 3 minutes, then check to see if the water level is just below the heating element. if so then it has to be the wash pump being plugged.
if not enough water then you should change the water inlet valve. some times they do get plugged but also make sure you are getting full water pressure to the unit as that could cause not enough water into unit. the faucet under sink could be at fault i have seen valve work but not let enough water in, so dont be surprised if you need a new valve.

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.

Check the riser tube coming from the pump assembly and be sure it isn't blocked or that something else isn't obstructing the pump intake area. Make sure the upper wah arm assembly isn't excessively loose on the spindle and losing pressure because it's leaking. You may have to remove the lower rack, lower wash arm and cover to see.
If everything is clear, it could be a worn or damaged pump impeller. If the machine drains normally, it's not the motor.

I'm having the same problem. Did some testing and found that the sprayer on the top rack is not even moving and hence not getting any water. Not sure what to do.
