Dishwasher rack rollers are the wheels that allow the upper or lower rack to slide smoothly in and out of the dishwasher. They ensure stable movement of the basket, even when fully loaded.

Worn or broken rollers can cause the rack to jam, tilt, or come off the rails. Replacing damaged rollers restores proper movement and prevents further wear to the guides. When selecting a part, check the dishwasher model and rack type to ensure compatibility.
