Strange, I only ever saw this happen on 20 year old dishwashers. Every modern dishwasher I have used, so long as your have correct plumbing and use a solid detergent requires no pre-washing. I put my dishes in caked in pasta and sauce and large food bits. The only things that don't go in are anything that would disrupt a disposal unit. No bones, no stringy things like tomato vines etc.
