Understanding the Problem
The lower rack wheels (rollers) allow the dishwasher's bottom rack to slide smoothly in and out. Over time the plastic wheels, axles, clips or roller assemblies can crack, wear down, or the retaining clips can fail. When that happens the rack can stick, wobble, fall off the track, scrape metal, or damage the spray arm. A damaged lower rack wheel is a simple, common problem and usually an easy DIY repair. Replacing the failed wheel, roller assembly, or track clip restores smooth operation. Be sure to match the replacement part to your dishwasher model—wheel designs and attachment methods vary by brand and model series.
Common Symptoms
Rack sticks or doesn’t roll smoothly, rack drops off the track, loud grinding or scraping when sliding the rack, wobbling rack, wheel visible as cracked/missing while rack is removed.
Common Causes
- Plastic wheel or roller worn from normal use
- Broken or missing retaining clip/axle that secures the wheel to the rack
- Cracked wheel housing or melted/deformed plastic from heat or detergent
- Bent or damaged rack track/rail that prevents proper wheel engagement

Helpful Repair Tip
Pull the lower rack completely out and inspect each wheel: spin them by hand, check for cracks or missing tabs, and look for broken clips on the rack rail. If one wheel is damaged, replace the corresponding wheel assembly (or both wheels on that corner) with the exact part for your model.
Frequently Asked Questions
Can I replace just one wheel, or do I need to replace the whole rack?
You can usually replace just the damaged wheel(s), axle, or housing—these are inexpensive and available for most models. Only replace the whole rack if the rack wire is severely rusted or the housing attachment points are broken beyond repair.
How hard is it to replace the lower rack wheels, and do I need tools?
Replacing lower rack wheels is generally an easy DIY job that takes 10–30 minutes. Tools required are minimal—often just needle-nose pliers or a small screwdriver to remove a retaining clip or pin. Always unplug power or disconnect power at the breaker before working if you'll be moving the dishwasher, and consult your model's parts diagram to order the correct replacement.
