I have Circulon hard anodised saute pans that are dishwasher safe. The one I use most has been in the DW about twice a week for at least five years without damage.
I also have cheap ikea frying pans that aren't dishwasher safe so may get damaged eventually but I'm happy to replace them every couple of years rather than wash them by hand.
I would say yes to the fridge shelves etc. Has anyone mentioned the washing machine soap drawer and kitchen bin yet? When I had a gas cooker, I also put the frame things in there, also BBQ grill.
My current (cheapest available Bosch) dishwasher has an extra spray head where you remove the top basket, attach the spray head at the back and it can be used to wash things too big to fit in otherwise - brilliant.
I think a lot of longetivity and success with dishwashers is down to your water hardness - I am lucky that mine is very soft - I usually use Aldi all in one tablets but if they are out of stock, I just get the normal ones and don't bother with salt or rinse aid and everything is fine.
My first dishwasher lasted 13 years of almost daily use and appalling treatment before dropping dead suddenly. I never rinse anything and only do the most basic scraping. Everything including pans comes out clean apart from things with egg on them.
Maybe not baking trays but I stupidly used to hand wash baking trays because I got some lovely ones in the sale from Sainsburys that I wanted to keep nice before realising that I hate washing them so am now going to put them in the dishwasher and if they get ruined throw them away and use disposable ones - lifes really too short to spend ages scrubbing baking trays and I am a 'low consumer' of lots of other things (hardly ever buy clothes and wear them for years for example) so I will allow myself this one wasteful thing that makes my life easier.
