i love dishwashers. i got my parents a new one...holy shit, it's been nearly ten years ago now. but the old one we had (which hilariously was only about ten years old then, but i guess it goes to show the builders putting the cheapest one in the house vs. me getting a quality brand and not the economy model) was just ridiculous. i love rice. but i'm pretty good about getting all the grains off before putting a bowl in the dishwasher. i could've gone weeks without having any rice, and still there'd be a couple grains that would then be sitting on top of the cups after it was run. new dishwasher and boom, never happened since.
it was one of those christmas gifts that my mom asked for jokingly and didn't expect me to actually do, but it's benefitted everyone, so why not. better than getting some crap someone uses twice and then sits in the back of a closet collecting dust.
