Fixing a malfunctioning dishwasher spray arm depends entirely on the specific problem you are experiencing. If the spray arm is clogged with white hard water scale or food debris, remove it and soak it in warm white vinegar for thirty minutes before clearing the tiny nozzles with a toothpick. If the spray arm keeps falling off or fails to spin, inspect the central plastic retaining nut, snap-in locking clip, and support bearing for cracks or wear, and replace any broken parts. Always verify that loaded dishes do not physically collide with the rotating arm during operation.
