So... my parents always do this. I never do and they get cross and take out the plates I have put in there to rinse them before turning the thing on. When I lived away from home I never had any issues with the dishwasher. I accept you have to clean the filter after each use but I argue rinsing one filter is more time/water efficient than rinsing every plate!!!!!
So - poll - rinse 'em or just shove 'em??
