Whirlpool Dishwasher WPW10078214, Replaces 4444444444444444
A cracked or broken upper rack wheel is the most common cause of a Whirlpool dishwasher upper rack that falls off its track, wobbles during the wash cycle, or won’t slide in and out smoothly. In most Whirlpool, KitchenAid, and Maytag dishwashers, the upper rack rides on a set of plastic wheels that roll along the rack rails — when one or more wheels crack, chip, or break off entirely, the rack loses its support, tips to one side, and can fall off the track mid-cycle. ⚡ Common wear item in Whirlpool-built dishwashers after several years of use. Part WPW10078214 is the genuine OEM replacement wheel that restores smooth, stable upper rack operation immediately — no modification required.

A broken wheel that has been running for a while can gouge or crack the plastic rail track it rides on — inspect both rail tracks for damage before installing new wheels. A damaged track will cause new wheels to crack again quickly, and the track is inexpensive to replace at the same time.
