A lot of people who have automatic dishwashers don't use them, but they might save money on water and electricity if they did.
Even though 68 percent of homeowners own dishwashers, about 20 percent use them less than once a week, suggesting people are hand washing dishes.

Except for removing large particles of food, pre-rinsing can actually hinder dishwasher cleaning, says the makers of Cascade. Enzymes in Cascade are designed to attach to food particles. Without particles, they have nothing to attach to, according to the Wall Street Journal.
Dishwashers made by Whirlpool have 'TargetClean' options in which sensors detect soil on dishes. Jet sprays focus on those casserole dishes and power off baked on food.
