So If any of you have had to use a dishwasher before you know what I am talking about.It is suppose to wash your dishes when you put them in but you have to wash the dishes before you put them in?I mean what is the point of a dishwasher if you have to clean the dishes anyways?I mean isn’t this a really pointless device they created?

And she is not a pointless device at all.
I always only ever held stuff over the garbage can so loose stuff would fall there, then put it in even without rinsing.
Except for certain stuff sometimes, it always comes out fine!
I guess you may have a seriously outdated model? Or you are doing more than you need? Have you ever tried not cleaning beforehand and see what comes out?
Seriously though, you just have to scrape of the cheese or whatever from the dishes and throw away the solid food. It's nowhere near as labour intensive as washing and drying your own dishes.
