The Whirlpool WPW10204141 Dishwasher Rack Adjuster allows convenient adjustment of the dishwasher rack height to accommodate different dish sizes. This replacement component attaches to the designated rack assembly and enables the rack to move between supported height positions. It allows users to create additional space for tall plates, cookware, glasses, and other items while arranging dishes for washing. A worn, cracked, or damaged adjuster may cause the rack to tilt, become difficult to move, or remain improperly positioned.
