Question about Whirlpool 24 in. DU1100XTP Built-in Dishwasher
My dishwasher is not cleaning, and the soap dispenser clogs up, and gets residue on the dishes. I have looked at some DIY sites, and everyone tells me to remove the lower spray arm. I can't get it off! There's a plastic screw in the middle of the assembly that I do not seem to be able to move, it just spins and spins.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Make sure your water is hot, at least 120deg f. Also, use least amount of soap you can get away with. Usually around 2 tablespoons for soft water. Use powdered soap not gel. Gel leaves a tiny residue each load and will clog up plumbing in dw after 4,5,or 6 years. Rinse agent such as Jet Dry is highly recommended.
Try the "Tang" trick. Orange Tang drink mix is mildly acidic. With an empty dishwasher, start and fill, then normal drain. On second fill, add a full jar of Tang then let the dishwasher run for a few minutes. Crack the door to stop the dishwasher and let it sit for several hours or overnight. Then close the door, push start and let the dw run through the remaining cycle. This will sometimes clean out the crud in the water lines.
Hope this helps! Ken

There is a screw at bottom of arm. Try turning arm before taking screw out. I believe water pressure turns the arm, so if the arm doe not tur while machine is working then you either have a blockage from pump to arm or pump not working properly.
