Dishwasher: Why can't I adjust the dishwasher rack height?

Some dishwashers allow you to adjust the upper dishrack height so you can load taller items in the bottom rack. If you can't adjust upper dishrack height, check the upper rack height adjuster and replace it if damaged. The upper dishrack also sags to one side when the upper rack height adjuster breaks. If you can't adjust the rack so it sits evenly, replace the upper rack height adjuster.
