Whirlpool Dishwasher Upper Rack Falling Off Track, Wobbling, or Won’t Slide? Rack Wheel WPW10078214 – Fix Rack Failures Fast

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.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dishwasher powers on and wash cycles run normally
• ✔ Lower rack slides and operates correctly
• ✔ Upper rack rail tracks confirmed intact and not bent or cracked
• ✔ Upper rack adjuster clips confirmed functional (if applicable)
• ✔ ONLY problem is upper rack wobbling, falling off track, or not sliding smoothly due to broken or missing wheels
