I use the finish powerball tablets with the red powerball and they are brilliant!!!!

I don't use a rinse aid as the little dispenser thing on my machine is broken but I never have any streaks or powdery residue left on the dishes.

I don't rinse them but make sure they are scraped really clean.

every now and again I put the little bottle of finish dishwasher cleaner through on an empty cycle but not that often and the dishwasher seems pretty clean.,
