The term 'dishwasher stages' refers to the different steps involved in the dishwashing process. The most common cycle is the 6-letter cycle, which includes pre-wash, wash, rinse, and dry. Pre-wash involves removing any large food particles from the dishes before they are placed in the dishwasher. Wash is the main cleaning stage, where detergent and hot water are used to remove dirt and grime from the dishes. Rinse follows the wash stage and uses hot water to remove any remaining detergent residue. Finally, the dry stage uses heated air to evaporate any remaining moisture from the dishes.
