Compressor motor sounds weird not filling up tank....making a really high pitched noise

How deep do you want to get into this?It sounds like the wash pump motor bearings that are worn.You can pull the unit out flip it over and wd40 the bearings in the motor or you can replace the bearings.Try to lube them first.

debris caught iside pump assy is what it sounds like

A loud high pitch whine while running the dishwasher means that there is something caught in the chopper assembly. To get to the chopper assembly you need to take the racks out and take the pump apart from the inside of the dishwasher. The chopper assembly looks like a metal grate with holes in it. And it might not even be stuck in the grate but somewhere in the pump area due to the water being pumped out, so the best idea is to take the whole thing apart and clean everywhere. However I do not recommend doing this unless you are completely certain you will remember where the screws and gaskets go, otherwise you risk damaging your pump or house from a leak or improper installation. You have been warned.

I had exactly the same problem. Just turn down the water pressure @ the valve on the water inlet line. While you have the toilet lid off, you may want to remove the fill valve (1/2 turn counterclockwise on the plastic nut attached to the water-in line), and clean the rubber diaphrams (there are 2). They will sometimes get gritty and this will cause some fill noises and leaking.

try washing on hottest cycle it may be the seal in the spray pump somethimes the rinse aid can put a glaze on the seal if that doesnt work you can replace just the front part of the motor( in australia) dont know where you are.
