My dishwasher just started leaving a white film on my dishes and leaving some food and discolloring my silverware after 10 years of cleaning without a problem

I replaced the water inlet valve that did not fix the problem. I took all of the jet rinse out and replaced it with new. That didn't work either. I put some vinegar in my dishwasher and that did better. I am at a stand still. It should just be simple. I took the whole dishwasher apart and no residue or hard water build up that I thought I would find. Looked brand new in motor and filter.
