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.

if it is just affecting the upper rack i doubt it is just a plugged spray arm (though i could be wrong). more likely than not you have a blockage on the intake of your spray pump motor. a series of bones, toothpicks, foreign material, etc could be blocking the entrance of the pump causing it to starve for water so to speak. you will more than likely need to remove the lower rack and spray arm to be able to disassemble the strainer and gain access to the sump. a complete model number would help bunches to.. alas
The broken bottom arm is probably preventing any water / water under pressure to get to the upper arm.
After you replace the lower arm, you should have much better cleaning in the top shelf.
While you are in there replacing the lower arm, recommend you remove the filter under it and clean the filter and any debris you find. Be careful of broken glass!
Good Luck!
A humming sound can be a failing wash motor (that drives the water pump) or it can be as simple as a blockage in the the pump area beneath the lower spray arm, under the filter.
Remove the spray arm and the filter top (screws will need to be removed)
Use a flashlight and inspect all over the sump area for debris that is blocking/jamming the impeller area. Reasemble and test with a short cycle.
If the dishwasher continues to make the same humming, it is time to replace the wash pump.
Good Luck! Post back here if you would like more guidance.
Could be a a couple different issues.. Not filling with enough water or food chopper broke or food chopper filter screen clogged.
Check water level: Run the DW and wait for the main wash to start (water will fill. pause then complete fill) The water should be no more than 1/4 inch below the heating element. If not there..replace water inlet valve.
Inspect food chopper: Remove lower spray arm and rear water supply tube to upper spray arm. Remove torx screws that secure the sump cover. Remove the rounded cover on the left side to expose the chopper assembly. Inspect for breakage of blockage. There may be an additional plastic screen to remove first.
CHECK THE SPRAY ARM HOLES,ARE THEY CLOGGED ??IF THERE NOT YOU MAY NEED THE PUMP REPLACED (NO PRESSURE).........BY THE WAY THE POWER DRIVE UNIT IS NOW REFERED TO AS A > MOTOR/PUMP WHICH IS NOT INCLUDING THE PUMP.IT'S THERE WAY OF ADDING CONFUSION WHEN WE ORDER PARTS. 1ST LOOK FOR CLOGGED SPRAY ARMS. LEAVE A RATING !!
I assume you are having spray issues, or a grinding noise. If odor is your issue, go to the bottom of the message.
For the dishwasher pictured above, Open the door. Remove the lower rack.
Push in the tabs holding the upper basket rail end caps and slide the caps up and out. Remove the upper rack. Clean the holes in the upper (or middle) spray arm.
Hold the lower spray arm still and rotote the thumb tab clockwise. Remove the lower spray arm. Clean the holes in the lower spray arm.
Use a small flat screwdriver to release the tabs holding the upper spray tube from the dishwasher inner wall and ceiling. Rotate the spray tube to the right and remove the tube.
Using a # 20 Torx bit, remove the (about 10) small screws holding in the top of the sump assembly. Remove the top section with the fingers all around it.
Using a # 15 Torx bit, remove the screw holding the round cover over the pump suction. Remove the cover (grab the tab sticking off the corner with a pliers and pull up.)
Anything stuck in the sump will now be visible. If the screen is completely clogged up, then the blade isn't wiping the screen clean. In this case, the screen should be replaced.
The screen is removable, but difficult to re-install. If you need to re-place it, put an open end wrench between the screen and the rotating blade to hold the spring compressed. Also, notice the screen isn't round. The flat edges fit only in the slots they came from.
If it's odor or white powder you want to clean out, use a dishwasher cleaning product such as Dishwasher Magic.
I tell every dishwasher customer: "You do not need to rinse your dishes before washing. But you do need to scrape them off."
