This Dishwasher Center Wash Arm Assembly rotates and sprays to evenly distribute water during the cleaning cycle. You will need this part if your spray arm is damaged and requires replacement. Replacing this part will require no disassembly or repair experience. Remember to unplug the dishwasher or shut off the house circuit breaker for the appliance before installing this kit. You must also turn off the water supply underneath the sink before installation. Helpful Tip: We 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.
