Understanding the Problem
The top rack wheels (also called upper rack rollers or roller assemblies) support and guide the top rack along its rails. Over time the plastic wheels or their axles can crack, wear flat, or come off the axle, causing the rack to wobble, catch, scrape, or fall off the track. Damage typically occurs from regular use, heavy loads, or from debris trapped in the track. When one or more wheels fail the rack won’t slide in and out smoothly, dishes can shift or tip, and the dishwasher may run noisier. Left unaddressed, a damaged wheel can gouge the rack rail or break the rack adjuster, making the repair more expensive. Replacing the worn wheel or entire roller kit is a simple fix that restores proper function and prevents further damage.
Common Symptoms
Top rack slides unevenly or jams, rack tilts or falls when extended, loud scraping/grinding noise when moving the rack, visible cracked/missing wheels or wheels that don’t spin.
Common Causes
- Plastic wheel wear or cracking from age and repeated use
- Wheel axle or clip broken or missing, allowing the wheel to fall off
- Debris, hard water buildup, or damage to the rack rail that stops the wheel from turning

Helpful Repair Tip
Pull the top rack forward, lift the front slightly and inspect each wheel. Spin each wheel by hand — a damaged wheel will not spin freely, be visibly cracked, or wobble on its axle. Replace any wheel that is cracked, flat, or missing.
Frequently Asked Questions
Can I replace just one wheel or do I need the whole set?
You can replace a single damaged wheel if the other wheels and clips are in good condition. However, because wear commonly affects multiple wheels, many people replace the whole roller kit (wheels, axles, and clips) to ensure smooth operation and avoid repeating the repair soon.
Is replacing top rack wheels on a GSD2220ZBB a DIY job and how long does it take?
Yes — this is a DIY-friendly repair that usually takes 15–30 minutes. You’ll typically pull the rack out, remove the end stops or lift the rack to free the wheel assembly, snap out the old wheel/clip, and snap the new part in. Keep the dishwasher manual or parts diagram handy to confirm orientation and correct replacement parts. If rails are damaged or internal clips are broken, the job may take longer or require additional parts.
