Is This the Right Part?

Common Symptoms

• Upper rack binds or is difficult to insert or remove
• Rack rollers come off the track or move off-center
• Rack support rail is visibly cracked, detached, or damaged
• Upper rack feels unstable during loading or unloading

Check Before Replacing

• With the dishwasher empty and unloaded, slowly slide the upper rack in and out and observe whether it binds or leaves the rail.
• Visually inspect the WP3385089 rail for cracks, detached sections, distortion, or missing end-stop components.
• Check that the upper-rack rollers remain seated on the support rail throughout the rack’s travel.
• Compare the affected rail with the opposite-side rail for obvious damage or abnormal alignment.
• Do not force the rack; stop if it catches and inspect for obstructing dishes, rollers, clips, or rail damage.
