Listen, I've got like three minutes of enthusiasm for this job. I'll take an item and put it where it fits. Once both racks are populated the dishwasher starts. At least there's something in there getting clean.
I've never understood why some people simply must overfill the machine, ensuring that nothing gets properly cleaned. Literally just run the machine twice. It will still use way less water than hand washing, and it will do a better job.
"Properly loaded" means the dishwasher can still do it's job while loaded to maximum capacity. Just putting stuff wherever means you run the dishwasher more frequently which wastes resources.
Absolutely, though if you have to run it twice anyway you don't have to cram it full on the first go no matter what. But I've seen some truly horrific stuff, plates and bowls just stacked on top of each other, no way for the water to get in all the crevices
