There are several distinct schools of thought involved in the proper operation of dishwashers. In fact, there ought to be a degree program for the whole automatic dishwashing syndrome (ADS) and half the course would be dedicated to negotiating with those who share or have access to your particular device. People tend to take their dishwashers very personally.
Individual members of western culture can be divided into two categories - those who don't mind emptying (but don't like loading) and those who don't mind loading (but don't like emptying). Hopefully, there is at least one of each in your household. Otherwise, you'll have a lopsided burden of unwanted responsibility contributing to inevitable resentment and frustration.
That doesn't even begin to compare to the enormous and unresolved controversy of cutlery up or down. Do you put handles down first? If so, you will have to grab forks, knives and spoons by the "business" end of the cutlery - the part that delivers food into your assimilation port. Or do you put handles up? If so, it makes them easy and more hygenic to grab, but some people argue the cleaning process is hindered by the cutlery tray itself as well as the logjam of utensils making contact together. There is absolutely nothing worse than spoons on top of spoons. Who can contradict what contentious domestic disputes have not been initiated with accusations about cutlery placement?
Then there are the "sweet spots" and favoured locations for specific vessels, plates and assorted items. Would anyone disagree orientation is one of the most extreme priorities? Angles must be correct in order to avoid unforgivable lingering residual moisture. Then, of course, any points of contact must be circumvented in order to escape permanent damage. Not only does it chip and crack your favourite dishes, broken pieces of crockery or tableware can contribute to a bottleneck in the kitchen drain.
