Everything works except the washing cycle. Could it be the motor?

Dishwasher will not clean dishes or even rinse spent detergent. I have manually filled it to rule out and inlet problem, also cleaned filter and checked for blockages but still no luck. I believe I have to replace the motor and or pump assembly. Any advice or input on where to best invest my time and money?

Unit cycles through but very little water is being pumped. No noises etc but not getting volume or pressure from the pump. Does drain OK. Is the pump and motor sold as a unit or can one buy pump alone?

Why still some remaining water inside at the bottom of the dishwasher after finishing ?

During the last cleaning cycle of our dishwasher, the normal cleaning sounds were abruptly replaced by a loud constant buzz, like something that was moving may have locked up. When opening the door, everything looked normal inside. We shut the door, cancelled the cycle, and waited for everything to drain out (no unusual noises). I have taken everything apart and found no blockages, nothing broken, or any other obvious problems. Looking at the wiring diagram, it says that the wash pump motor has a run winding (3-7 ohms) and an aux. winding (6-10 ohms). Removing the wash pump motor connector, I saw 3 blades (2 silver in color, each w/rounded ends and one gold in color w/a square end). The resistance between the 2 silver blades is 6.2 ohms. Gold blade to either silver blade is open, so I figured bingo-I lost one of the 2 windings, bad motor. Now that I have the motor fully removed, it looks like the gold colored blade is just a ground. If so, how do I check the 2nd winding (to verify this is a bad motor) with just 2 blades? The shaft does turn easily, with no bearing noise or end play. The 23.5 uF (+/- 5%) capacitor tests in spec. at 22.6 uF. The dishwasher is 25 months old and is probably used 6-8x a week. The drain pump motor shows as 15-19 ohms on the electrical drawing, I measure it at 19-21 and it also turns easy for a 1/4 turn and then is noticeably harder to turn the next 1/4 turn and keeps alternating between easy and hard a quarter revolution at a time. A little weird, but wasn't this motor used (without the noise) to remove the water in the bottom of the tub when the cycle was cancelled?
