We had a glass break on the bottom of the dishwasher, and now I'm paranoid about putting anything down there.
Heeeelp !
Heeeelp !
I think that all dishwashers come with that feature now.
I'm fortunate to have a dishwasher that I can turn off the heated dry. In fact, I never use the heated dry, the water is hot enough without it and everything comes out spotless.
