I am banned from the dishwasher because of this. Threw in a set of valve covers and was drinking beer out in the garage. Too many beers and I forgot all about the valve covers. The next day wife opened up the dishwasher to get a coffee cup or something. Morning after many beers and 3 hours sleep waking up to a pissed off wife is not good. Needless to say she got a new dishwasher.
