I bought a new home and the former owner replaced the old dishwasher with the GE GSD2100V50BB.  When I first used it, it would not dry the dishes fully and would leave some soap spots on many of the dishware inside.  However, that issue soon remedied itself after buying rinse aid. The dishwasher does leave  residue and food particles on the dishes that needs to be rinsed/ washed off from time to time, but overall works fine and gets the dishes clean.
