It rotates during the wash cycle, spraying water through strategically placed openings to reach dishes, glasses, and cookware. Proper water distribution supports thorough cleaning and reduces leftover debris. Replacing a damaged or clogged spray arm can restore water coverage and improve washing results when the original part is faulty. Designed for compatible dishwasher models, this replacement part supports consistent cleaning performance. Check your dishwasher’s model number and the part number before purchasing to confirm compatibility.
