Thank you for your suggestions. Sorry for the long delay and the long post.
1. I generally use the Normal or Heavy cycles - Normal for small loads, heavy for large loads. I do not believe that I am using the wrong cycles. Using the sanitize option makes the dishes dry so quickly that it nearly bakes soil deposits onto the glasses so I don't use it very often.
2. Yes, cleaning performance has never been optimal.
3. Dishes are scraped, but generally not rinsed before being loaded. Large particles are not allowed as the dishwasher will just chop them up and leave them on dishes. Re-deposition seems worse on the top rack. Anything burned on gets soaked and scrubbed before being loaded.
I was not able to find any kind of obstruction in the spray arms and the machine fills up with the proper amount water. In the past I have used machine cleaners and CLR cycles because I noticed mineral deposits on the heating element with no improvement to wash performance.
I have played around with adding additional detergent with positive results! I have a bottle of finish gel and have been adding about 2 Tbsp to the floor of the machine before starting in addition to 1 detergent pack in the main dispenser. Instead of large spots and stuck on redeposits, I now have much smaller spots.
Here are some pictures. Most all glassware comes out like these pictured. These deposits will come off if you scrape them with a fingernail. Very annoying to have to do this to every glass, especially wine glasses.
The surface of these glasses felt smooth to the touch, so I don't think they are pitted...
I think it's safe to assume that the glassware is not the problem since we never had these issues with previous dishwashers while using the same dishes.
