Understanding the Problem
Many Kenmore dishwashers use plastic wheel/roller assemblies on the upper rack to allow it to slide in and out smoothly. Over time the plastic wheel, axle or clip can crack, wear down, or fall off, causing the rack to wobble, derail, or stick. Diagnostic steps: 1. Remove the upper rack completely: pull the rack forward to its stops, then lift the front of the rack to release it from the track (some models require releasing a stop clip or pressing a small tab). Pull the rack out of the tub. 2. Inspect the rollers and axles: look for cracked plastic, missing wheels, flattened tread, broken or bent axle pins, or a loose wheel that wobbles on the axle. 3. Inspect the track and end stops: check for cracks in the track or broken end caps that let the rack exit the track. 4. Spin each wheel by hand: a good wheel will rotate freely and smoothly; a failing one may bind, squeak, or wobble. Replacement/repair steps (how to fix): 1. Purchase the correct replacement roller(s): look up your Kenmore model number (on the tub rim or door) and buy the matching upper rack roller assembly. Many rollers are sold in pairs and include the axle clip. 2. Gather tools: flat-head screwdriver, needle-nose pliers, work gloves, and the replacement rollers. Optional: small putty knife if clips are tight. 3. Remove the damaged roller: for most Kenmore models the wheel snaps off an axle or the axle pin is held by a plastic clip. Use a flat screwdriver or needle-nose pliers to pry off the retaining clip or release the tab, then slide the wheel off the axle. Keep any small clips if they are reusable, but replace if damaged. 4. Install the new wheel: align the wheel assembly on the rail/axle and press until it snaps into place. If your replacement uses a new clip, secure the clip over the axle until it clicks. 5. Reinstall any track end caps or stops if removed: ensure they seat fully so the rack cannot roll off the rail. 6. Slide the rack back into the dishwasher: make sure it runs smoothly on the track. Cycle it in and out several times to confirm there is no binding or skipping. 7. Test a short wash cycle to ensure the rack remains aligned during operation. Safety note: always disconnect power to the dishwasher (unplug or switch off the circuit breaker) before working on it. Wear gloves to protect your hands from sharp edges and use eye protection if prying brittle plastic pieces.

Helpful Repair Tip
Confirm the roller is the problem by removing the rack and spinning the wheel. If it wobbles, binds, or the wheel piece is visibly cracked, replace that roller—you can often replace only the wheel and clip rather than the whole rack.
Frequently Asked Questions
How do I find the correct replacement roller for my Kenmore dishwasher?
Locate your dishwasher model number on the inner door rim or on the tub edge. Use that model number on manufacturer parts sites or major parts retailers to find the compatible upper rack roller assembly. Many listings show photos so you can match the shape of the wheel and clip.
Can I replace the upper rack rollers myself or should I hire a technician?
Yes — replacing upper rack rollers is usually a straightforward DIY job that takes 10–30 minutes per wheel for most people. It requires only basic tools and no plumbing or electrical work. Hire a technician if the track itself is cracked or if multiple components (rack, track, and clips) are damaged and you prefer a professional diagnosis.
