Your dishwasher probably isn't level front to rear. As for the track problem, there could be a missing stop or some damaged hardware. The racks are supposed to be removable but not on their own.
Let’s assume the dishwasher is working correctly because it turns on but nothing else works. If a dishwasher does not fill with water at the correct level, it will not continue to advance. You’re not getting water. Check hot water valve under sink. The one for dishwasher. Maybe someone shut it off on accident. Also, Water deposits like lime, calcium will build up and clog the screen on the dishwasher’s hot water intake valve. That would need cleaned out. The valve itself will go bad alone. Regardless, once it’s getting water the dishwasher will run. Please let me know!!
Check for bent drain hose, make sure it’s not push in to far down in to drain trap, if it’s hooked up to garbage disposal check for blockage at that connection and what u want to do is see how good of the stream comes out from the end of drain hose just get big enough backer and fill unit by start cycle then drain unit by canceling cycle will put unit into drain mode This will give you some ideas we’re to look for problem
