The Dishwasher Lower Wash Arm Bearing is an upper nylon radial bearing that sits on top of your dishwasher's lower spray arm and helps the spray arm rotate freely. Remove the lower dishrack and unscrew the retainer holding in the bearing counter clockwise. Installing this part will require no disassembly of the appliance or repair experience. Helpful Tip: We also recommend using affresh® Dishwasher Cleaner (item W10282479) to help remove limescale and mineral build-up that can be unsightly and affect your dishwasher’s performance. *affresh® brand products are owned and distributed by Whirlpool Corporation.
