This Dishwasher Upper Rack Adjuster Kit allows you to move the upper rack of your dishwasher up or down to provide more space. If a wheel bracket breaks, the dishwasher will sag to one side. This kit includes two adjuster arms, two adjuster actuators, two gray adjuster covers, two gray adjuster housings, four screws, and one instruction sheet.Replacing this part will require basic hand tools, some disassembly of the dishwasher and novice repair experience. You must unplug the dishwasher or shut off the dishwasher's water supply underneath the sink before installing this part.Helpful Tip: We also recommend using Affresh® Dishwasher Cleaner (item 1373065) to help remove limescale and mineral build-up that can be unsightly and affect your dishwasher's performance.
