Faeryn Savage's post was accurate except for the plastics. I personally would not stick plastics in the dishwasher or the microwave. In fact, if you can avoid having your food and water contact plastics at all, then that would be best for your health. Also, any dishwasher I have used is not useful because in order for it to work, you have to wash the dishes before/after running them through the dishwasher (which makes no sense to me). I have often called them dish dirtiers.
Machines for washing clothes do a much better job of actually washing the clothes.
Dishwashers just create a large amount of needless conflict and redundancy. If I were you, I would pare down the amount of dishes that I own and just wash those by hand.
