Understanding the Problem
Over time the plastic wheels, axles, and clips that let the dishwasher's lower rack slide in and out wear out, crack, or snap off. When a lower rack wheel is damaged the rack can bind, tilt, scrape the tub, or fall from the track — causing noisy operation and possible tub damage. Often only the wheel or the small roller assembly needs replacing, not the whole rack. Different manufacturers use slightly different wheel assemblies (snap-on roller clips, axle pins, or two-piece rollers). Dirt, hard water deposits, or impact from heavy pots can speed wear or break the retaining clip. Before buying parts, confirm the exact wheel style by removing the rack and inspecting the roller housing and how it clips or screws into the rack frame.
Common Symptoms
Rack not rolling smoothly, scraping/noisy operation, rack tilting or sagging, wheel missing or visibly cracked, rack falling off track
Common Causes
- Plastic wheel, axle or retaining clip worn, cracked, or broken from age or impact
- Debris, hard water scale, or food buildup jamming the roller or track
- Incorrect reinstallation after cleaning or loading heavy items that bent the wheel assembly

Frequently Asked Questions
Can I keep using the dishwasher if one lower rack wheel is missing?
Short-term you can run it, but it's not recommended. A missing or broken wheel lets the rack sag and rub against the tub, which can scratch or chip the finish and lead to more damage. Replace the wheel soon — replacement rollers are inexpensive and typically easy to swap yourself.
How do I replace a lower rack wheel?
Steps overview: 1) Pull the lower rack out and remove it from the rails. 2) Identify the wheel style (snap-on roller housing, axle pin, or screw). 3) Remove the old wheel/clip (usually snaps or lifts out; some use a small retaining pin). 4) Clean the track of debris/hard water buildup. 5) Install the new wheel/roller and secure the clip or pin, then reinstall the rack and test. Always match the replacement to your dishwasher model for correct fit.
