The Whirlpool WP8270019 upper dishrack wheel assembly helps the dishwasher’s upper rack slide smoothly in and out for convenient loading and unloading. Designed to attach to the upper rack and engage with the dishwasher’s guide rails, this assembly allows the rack to move while supporting its proper alignment during everyday use. Functional wheels help reduce sticking, uneven movement, and difficulty accessing dishes and utensils. Replacing worn, cracked, broken, or missing wheels can restore smoother rack operation and improve the dishwasher’s usability.
