What kinds of simple machines are in a dishwasher?

Well, honey, a dishwasher is a magical contraption that's got all sorts of simple machines working together like a well-oiled machine. You've got your humble inclined plane in the form of the door, some good ol' fashioned wheels and axles in the racks, and let's not forget about those handy dandy screws holding everything together. It's a regular simple machine party in there!
