This Dishwasher Upper Rack Adjuster Kit allows you to move the upper rack of your dishwasher up or down to provide more space. If your dishwasher's upper rack is sagging to one side, replacing this part may alleviate the issue. This high-quality and easy-to-install kit includes (2) adjuster arms, (2) adjuster actuators, (2) gray adjuster covers, (2) gray adjuster housings, (4) screws, and an instruction sheet. Replacing this part will require basic hand tools such as a multi-screwdriver, some disassembly of the dishwasher, and novice repair experience. Before installing this replacement part, remember to unplug the appliance or shut off the house circuit breaker to ensure safety. Also, make sure to turn off the dishwasher's water supply below the sink. Helpful tip: We recommend using affresh® Dishwasher Cleaner (item W10282479) to help remove limescale and mineral build-up, which can be unsightly and affect your dishwasher’s performance. *affresh® brand products are owned and distributed by Whirlpool Corporation.
