I will try vinegar then.  Some folks here said it was a good step, but I understand how it could be a problem if left to soak too long.  The only problem is I think the sprayer arms have gunk in them.  I believe this as I can see some hard water crust where the two halves on the plastic spray arm meets.  I may try them in the sink upside down as the vinegar in the bottom of the tub will do nothing for the spray arms in the terms of soaking.

Holes are clear, but I will clean the arms as well.  Vinegar is in the dishwasher well soaking already.

I did have a few bit of "stuff" that came out of the bottom spray arm.  I put masking tape over the holes and filled the arm with vinegar, which worked fairly well.  Running the vinegar cycle right now (which soaked overnight) and to get the full use of the vinegar, I disconnected the drain pump for the first three drain time and then reconnected it.  So I did notice a big difference with more water in the tub.  But I still do not know what the normal sound or water level should be.  And of course I did hear a difference as it even tripped the overflow sensor due to missing that first drain cycle (or 3 to be correct). 

Of my many questions, would adding enough water to trip the overflow sensor after the start-up drain cycle help in the following wash/rinse cycles as the rest of the drain cycles are shorter than the first cycle? I will have to move stuff and clean the basement to prepare for the call to the water company to solve the low pressure, or low volume issue as I have no idea what they will do to fix it, if anything.  I have heard of a test that will let you know how many gallons/min are being delivered to the unit which from memory involves a measured container and a stop watch.  But my question would be what is the required minimum volume for my dishwasher?

 There is still "dirty" water in the quite sump area after this vinegar run.  Is it normal after a complete normal wash cycle to have dirty water in the quite sump?  How does the quite sump ever really get clean?  What does the turbidity sensor do in the terms of actions the dishwasher will take if it senses the water is dirty?  Can I test the sensor with a multimeter?  I am soaking the heating element which has some hard water crust on it with paper towels soaked with vinegar.  Hopefully that is the cause of the dirty water in the sump this time.  And then I will run a complete cycle without any dishes but with soap, adding water after the first drain and see the condition of the quite sump water.  Then run a complete cycle with clean glasses on the top shelf and see if they are clean or dirty, but any help before hand that would guide me in the run direction would be great.  Thanks

Could your fill valve not be opening fully during the fill? I know you said you checked the screen but couldn't deposits(mineral) inside the valve prevent a full flow?
I have also read where some people remove the flow restrictor in the valve without any problems when they have low water pressure.

Is there an easy way to check to see if it is flowing as it should? Do all models of dishwashers have restrictors?  I will check the donor unit (same make, model and year) to see if it has a restrictor as I cannot remember seeing one when I check the inlet filter but I was not looking for one at that time.  Thanks for the help.

If you could rig it up to fill with the door open, then you could see how well it pours into the machine, otherwise just have to go by how much is in the bottom after it stops filling.
 
The restictor is inside the valve at the bottom of the strainer-at least on a Kenmore/Wpool. And Yes I do believe all of them have restrictors.

All it takes on my model is to use a screw driver to push in the latch on the door to trick it to work with the door open.  I will do a visual on the fill, but have no norm to base my results on. I checked the donor unit fill valve and did not see anything that looked like a restrictor. Is it just a washer with a smaller hole in the center?

Best I remember on mine, it was like an o ring that fit around a plastic disk(?)-the disk has holes in it and the strainer fits over this. When you pull the strainer out then you see the other piece(disk) in the bottom of the valve.
 
Maybe just switch the valve off the donor onto this machine and see if you get more water or you might just need a new valve.
