A bottom spray arm repeatedly falling off usually indicates a worn-out, cracked, or stripped plastic locking nut, retaining ring, or central mounting support. Over years of high-temperature wash cycles and water pressure changes, plastic components degrade or lose their grip. Additionally, heavy food debris or hard water buildup can jam the rotation, placing abnormal torque on the locking clip. Always disconnect power to the appliance before performing any maintenance inside the tub. You can verify the fix is permanent when you install a new OEM retaining clip and test that the spray arm stays locked firmly in place while spinning freely by hand.
