Only on your silverware? Do you see it on plates and glasses? Are lou looking for it on other things?
My first guess would be rust in the system somewhere.
See it the spots are on anything else.

Nope, it cleans (and dries) everything else very well.

I had this problem with my steak knives. I'd wash them in the dishwasher. They came out clean but with rust spots on the blades. I'd rub the blades off with paper towels. Not sure where the rust came from. I believe they are made of stainless steel, definitely not silver or silverplate. This happened about five years ago. For some reason,it has now stopped. I do keep the rinse aid dispenser of my DW full of Jetdry.

I also use Jetdry, Cascade for detergent.

Hope this helps...
