Dishwasher Lower Rack Wheels Broken
Lower rack wheels that are cracked, missing, or no longer rolling show up as a rack that drags, catches, or grinds every time you pull it out or push it back in -- and in worse cases, as a rack that will not sit level, sags at one corner, or lets the spray arm underneath knock against it during a cycle.
The lower rack rides on a row of small wheels, also sold as rollers, mounted where the rack frame meets the rail on each side of the tub. Each wheel normally spins freely on a short plastic post that is part of the rack frame itself. A wheel that is simply cracked or worn usually just needs the wheel replaced; a wheel that is missing entirely along with a visibly broken or snapped-off post where it used to sit means the rack frame at that mounting point has failed, which changes the repair.
If the rack is falling or dropping rather than dragging on damaged wheels, see Upper Rack Falling for the height-adjuster and end-cap failures that cause a rack to drop instead of just roll poorly.
Safety first. A dishwasher combines household electricity with a pressurized water supply line and a tub that can hold hot standing water.
- Shut off power at the breaker. Most dishwashers are hardwired rather than plugged into an accessible outlet, so the breaker is the actual disconnect -- turning the dial or touchpad off does not remove power from the unit.
- Close the water supply valve under the sink or at the shutoff before disconnecting any hose, valve, or fitting.
- Standing water in the tub may be scalding. Let it cool before reaching in with bare hands.
- Never work on a unit that is still wired live. Confirm power is off at the breaker itself, not just at the control panel, before touching internal components.
Most Likely Causes
- Worn or snapped wheel roller — The most common cause. Years of rolling in and out under a full load of dishes gradually wear a flat spot into the wheel or crack the hub where it meets the axle post, until the wheel finally shears off or seizes and stops turning. Sold as Rack Roller (WD12X272, WD12X0272, or WD28X305) or, on some models, Lower Dishrack Wheel (W10195416).
- Cracked rack tine at the wheel mount — If a wheel is missing along with the small plastic post it rode on, the tine or post itself has broken rather than just the wheel. Check the mounting point closely before assuming a replacement wheel alone will fix it -- a wheel cannot stay seated on a snapped post.
- Broken or missing rail stop — The stop at the end of each rail keeps the wheel from rolling past the end of the track when the rack is pulled all the way out. A missing or broken stop lets the wheel run off the rail edge repeatedly, which is a common way a wheel that started out fine ends up cracked or snapped off. Sold as Stop (8565920, 8524581, W10082860, 8562015, or 8524582 depending on model).
- Bent or corroded rail — A rail that has rusted or been bent slightly out of line forces the wheel to ride at an angle instead of rolling flat, wearing it unevenly and eventually cracking it even when the wheel itself started out sound.
- Missing end cap — Similar to a missing rail stop, a missing cap at the open end of the rail lets the whole wheel run off the track, and the sudden drop when it does is a common way a wheel cracks or its axle snaps. Sold as Cap (WD12X344 or WD12X0344).
How Many Wheels Does Your Rack Have?
Lower racks typically carry four to eight wheels depending on the model -- a simple design with one wheel at each corner, or a heavier-duty design that adds a second wheel partway along each side rail to support a fully loaded rack without sagging in the middle. Count the wheels on your rack before ordering parts, and check whether your model's replacement is sold as a single wheel or as a matched set, since a mismatched wheel height on one corner can tilt the rack even after the repair.
How to Check Each Part
- With power off at the breaker, pull the lower rack all the way out and set it on a towel where you can see the underside clearly.
- Spin each wheel by hand and check that it turns freely -- a wheel that is cracked, flat on one side, or does not turn at all has failed.
- Look closely at the post each wheel rides on; if a wheel is missing, confirm whether the post is still intact or snapped off along with it.
- Check both rails for the stop and end cap pieces at the far end of the track and confirm neither is missing or broken.
- Run a finger along each rail checking for rust, pitting, or a section that feels bent compared with the rest of the track.
DIY Repair or Call a Technician?
Replacing rack wheels, a rail stop, or an end cap is one of the easier dishwasher repairs available -- the wheels typically snap onto their post by hand or with a single screw, and stops and caps clip into place without tools. None of it involves the water supply, drain, or wiring, so there is little risk in attempting it yourself.
A cracked rack tine (the post itself, not just the wheel) is usually still a DIY fix, since a replacement wheel and post combination is often sold as a single assembly on the affected model. Call a technician only if the rack frame is cracked in multiple places or the rail itself needs replacing and you are not comfortable removing the rack assembly from the tub.
Preventing Repeat Wheel Failures
Load heavier items like pots and pans toward the center of the rack rather than concentrated over one or two wheels, since uneven weight distribution wears the wheels closest to the heavy items much faster than the rest. Avoid forcing the rack past its normal stopping point when it feels stuck -- that is one of the most common ways a rail stop or end cap breaks, which then accelerates wear on the wheels themselves once the stop is gone.
If one wheel has already failed, check the other three (or more, on models with extra wheels) at the same time -- they have carried the same load for the same number of cycles and are usually close behind the one that just failed.
Check Your Exact Model
Once you have narrowed the cause down to a part type, confirm it against your exact dishwasher rather than guessing from the brand alone. Use the model and part lookup tool to search by your dishwasher's full model number, or start from one of these confirmed model pages to see the exact parts list for that unit:

How to Confirm Before You Buy a Part
Before ordering any replacement part, take a minute to confirm fitment -- it is the difference between a repair that works the first time and a part that has to be sent back.
- Find the model/serial plate. On most dishwashers it is on the edge of the door (visible when the door is open) or stamped into the metal rim of the tub itself, just inside the door. See how to find your model number if you cannot locate it.
- Read the full model number exactly as printed, including every letter and dash -- manufacturers reuse near-identical model numbers across different production runs that take different parts.
- Verify the part fits that exact model using the model and part lookup tool before you buy, rather than assuming a part that looks the same will fit.
The full model number matters more than the brand and appliance type alone. Manufacturers commonly reuse one tub and door design across many model numbers over several years, changing the exact pump, spray arm, or control board partway through the run -- so two dishwashers that look identical side by side can still take different parts.
