A dishwasher arm works through rotational motion driven by water pressure. As water is pumped into the dishwasher, the arm spins, distributing water through holes along the arm to effectively clean the dishes. Ensure the arms are not obstructed by dishes and are free from debris for optimal performance. Regular maintenance, such as cleaning the nozzles, enhances the dishwasher's efficiency.
