How does a dishwasher work?

A dishwasher saves you the trouble of having to wash dirty plates, cups, and dishes after every meal. The dishwashing process is simple. All dishes and cutlery are loaded into the built-in racks and the machine is switched on.

A dishwasher begins its operations by spraying hot water (around 150˚ F) at the dishes to dislodge food particles. A mixture of detergent and water is run over the dishes to clean them followed by another spray of water to remove all traces of detergent residue. A single dishwashing session will involve multiple wash and rinse cycles.
