Go to StoreThis Dishwasher Middle Spray Arm rotates and sprays water to clean the dishes inside the dishwasher tub. If it has been damaged, and is no longer connected to the pump, you may need to replace this part. To access the part, remove the lower rack out of the dishwasher and press the tab on the existing spray arm retainer to remove. Replacing this part will require minor disassembly of the appliance and novice repair experience. Remember to unplug the dishwasher or shut off the house circuit breaker for the appliance before installing this part. You must also turn off the water supply underneath the sink before installation.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.
