Here's my take. I don't put any pots and pans in the dishwasher as the cleaning process can be too harsh, sometimes affecting the finish.
Our dishwasher goes off once, every evening, filled with everything used during the day. Modern dishwashers are energy and water efficient. To clean everything in our dishwasher by hand would need two or three changes of hot water, soap etc. And even with hand washing, the crockery still has to be put into the bowl, washed, dried and then stored away, so there's no saving there. And 'yuk' to dirty water in the washing up bowl.
