No dishwasher is perfect, and neither is its drying cycle. You're not always going to experience a perfectly dry load every time you run it. For instance, plastics don't dry as well as silverware or other dishes. But that doesn't mean you can't do some things to help your dishes along. Make sure you use a rinse aid, load the dishwasher properly, don't overfill it, and make sure your heated dry cycle is on before you consider any other more complicated problems.
