Lol at all the people who want to throw out the whole appliance. Wait until they find out how much former piss is in all sources of water, what allowances there are for gross things in prepared food, and what's on every surface in human environments. Earth is one big mixing pot.
Give it a steralise cycle and it'll be cleaner than the counters around it, by any objective measure.
I am curious about the almost nothing else bit. What got put in the poo-poo cycle?
Edit: Psychology is another thing, and that's valid I guess, but man I can't imagine having disposable dishwasher kind of money.
