I usually piss in the dishwasher right after loading it up and before turning it on. Never had any issues at all, the dishes come out just as clean and dry as if I don't piss in the washer, and honestly it makes the rather tedious chore of doing the dishes more fun! I can say the same about the laundry basket when I'm about to do a load of laundry, after all if you wash it right away you don't notice any difference at all.
