Samsung Dishwasher: Lower Rack Wheels Broken
Quick answer: When the lower rack sticks, tips, drops on one side or grinds as you slide it, one or more of its wheels have cracked, split, or come off their axles.
- Let the tub cool before pulling the rack out to inspect the wheels after a cycle.
- Wear gloves; cracked wheels and rusted rack wire have sharp edges.
- Do not run the dishwasher with a loose wheel; it can fall into the sump and jam the pump.
Why are my dishwasher lower rack wheels broken?
When the lower rack sticks, tips, drops on one side or grinds as you slide it, one or more of its wheels have cracked, split, or come off their axles. The most common causes are rollers worn or melted from years of heat and heavy loads, a broken axle clip or stud that lets the wheel fall off, a rusted rack frame that no longer holds the wheel, and a bent or debris-filled track on the tub that chews the wheels.

Most Likely Causes, in Order
1. Lower rack rollers
Each wheel is a plastic roller clipped onto a stud on the rack. Heat, detergent and heavy pots make the plastic brittle until the wheel cracks, flattens, or the center hub splits and the wheel wobbles or falls off.
How to check: Pull the rack all the way out and turn it over. Spin each wheel; it should turn freely and sit straight on its stud. Look for cracks around the hub, flat spots, missing wheels, and wheels that slide off the stud with a light pull.
Fix: Snap on new rack rollers; most simply press onto the stud or clip into the rack wire. Replace all of them at once if more than one is worn. (Difficulty: Easy)

2. Roller axle and retaining clip
On many racks the wheel rides on a separate axle held by a clip or a stud that is part of the wheel. A broken clip or a snapped stud lets a good wheel drop off repeatedly.
How to check: If a wheel keeps falling off, look at the stud or axle it mounts on. A snapped stud leaves a short stump on the rack wire; a broken clip lets the axle slide sideways.
Fix: Replace the axle or clip, or use a roller kit that includes its own stud that clips onto the rack wire. (Difficulty: Easy)

3. Rusted rack frame
When the vinyl coating chips, the steel wire underneath rusts through. The wheel mounts and tines weaken, wheels no longer stay on, and rust flakes end up on dishes and in the pump.
How to check: Inspect the rack wire around each wheel mount and along the tines for orange rust or bare metal. Press a rusted section with a thumb; if it flexes or crumbles, the frame is beyond repair.
Fix: Touch up small chips with vinyl rack repair paint and tine caps. Replace the lower rack if the wheel mounts or several tines have rusted through. (Difficulty: Easy)

4. Tub track and door rails
The lower rack rolls on ridges in the tub floor and onto the inner door panel when pulled out. Debris, a bent door rail or a warped tub edge makes the wheels catch and break.
How to check: With the rack removed, run a finger along the tub ridges and the door edge where the wheels cross. Feel for food buildup, a raised edge, or a dented guide. Slide the empty rack slowly and note exactly where it hangs up.
Fix: Clean the tracks and straighten or replace a bent door rail or guide. (Difficulty: Easy)

Frequently Asked Questions
Are dishwasher rack wheels universal?
No. Wheel diameter, the mounting stud shape and whether the axle is included vary by manufacturer and rack design. Match the roller to your rack style before ordering.
Why do my rack wheels keep breaking?
Repeated breakage usually means a rusted stud that no longer holds the wheel straight, a bent track that side-loads the wheel, or overloading the rack with heavy cookware. Fix the mount or track before installing new wheels.
Is it worth replacing the whole lower rack?
If the frame is rusted at the wheel mounts or many tines are bare, a new rack is the lasting fix. If the wire is sound and only the wheels are worn, a roller kit is far cheaper and takes minutes.
When to Call a Professional
Rack wheels rarely need a technician. Call one only if the tub floor or door rail is warped so the rack cannot roll even with new wheels, or if a fallen wheel has jammed the pump and the dishwasher now fails to drain.
