How to Repair a KitchenAid Dishwasher Upper Rack
Most KitchenAid upper-rack problems, cracked wheels, chipped-vinyl rust, or floppy fold-down tines, are cheap component repairs rather than a whole-rack replacement. Plan on 20 to 45 minutes at a beginner level, all with the rack out of the machine.
Match the fix to the symptom#
Years of heavy loading chip the vinyl off the tines (which then rust), crack the wheels from heat cycling, and wear out the fold-down clips. The table sorts the symptom to the repair, and only one of them, a sag to one side, is actually the height adjuster (part W10350376) rather than the rack itself.
| Symptom | Likely cause | Repair |
|---|---|---|
| Rack will not slide smoothly | Worn or cracked wheels | Replace the wheels |
| Rack tilts or sags to one side | Failed adjuster or wheel | Replace the adjuster (W10350376) |
| Rust spots on the rack | Chipped vinyl coating | Seal with rack repair paint |
| Rollers grinding | Flat-spotted wheels | Replace the wheels |
| Fold-down tines will not stay up | Broken clip spring | Replace the clip |
| Brown flakes on dishes | Exposed wire corroding | Repair the coating or replace |
Before you start#
| Category | What you need |
|---|---|
| Tools | Needle-nose pliers, flat screwdriver, food-safe vinyl rack repair paint |
| Parts | Whatever the fault calls for: a rack wheel kit, vinyl repair caps, or a tine-row clip |
| Time and level | 20 to 45 minutes, Beginner |
Safety warning: No electrical work required. All repairs are done with the rack removed from the dishwasher. Handle exposed rack wire ends carefully, since rusted tines can be sharp.

Repair 1 - Replace the wheels#
Pull the rack out, squeeze the blue or gray stop tabs at the rail ends, and slide it free onto a towel. Each wheel is held by a plastic axle clip or a molded end cap: compress the clip with needle-nose pliers and push the wheel off, or unclip the whole end cap. Press the new wheel on until the clip snaps into its groove and confirm it spins freely. A KitchenAid upper rack usually has four wheels plus the two on the adjusters. Reinstall and check that it glides without grinding.
Repair 2 - Seal chipped vinyl to stop rust#
Inspect every tine tip and cross-wire junction where dishes rub. Bare metal reads silver at first and brown once it rusts. Sand any existing rust back to clean metal with 220-grit paper or a rust eraser and wipe with rubbing alcohol so the paint will grip. Brush on a food-safe vinyl repair paint, covering the bare metal and overlapping the good coating; for tine tips, press-on vinyl caps are faster and thicker. Let the paint cure a full 24 hours before running a cycle, or hot water will wash it off.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

Repair 3 - Replace a fold-down tine clip#
The fold-down rows pivot on clips with a detent that holds them up or down; when the spring breaks, the row flops. Slide the tine row sideways off the broken clip, pry the clip out of its frame hole with a flat screwdriver, and press the new clip in until it snaps. Re-engage the row and confirm it holds firmly in both positions.
Repair or replace?#
Replace the whole rack only if more than ten tine tips have rusted through, the frame is bent so it will not sit level, the rail ends are too corroded to take new adjusters, or a full repair would top 50% of a new rack. Otherwise, sealant, wheels, and clips are almost always the economical call. To make a repair last, load heavy items on the lower rack, do not force oversized dishes between the tines, and touch up any chip as soon as you spot it.
