Problem
The upper rack of your Whirlpool / KitchenAid / Kenmore dishwasher keeps collapsing on one or both sides. If you look at the back corners of the upper rack, you'll see a plastic wheel assembly with gear teeth — that's the rack adjuster. These plastic wheels are notorious for cracking after 3-5 years because they bear the weight of fully-loaded dishes.
Which Part?
- OEM number: W10350375 (newest revision), W10712395, WPW10546503, W10195840, W10195839
- Why so many numbers: Whirlpool used different model-years with slightly different revisions. All fit the same slot.
- Original Whirlpool: $25-40 per adjuster (you need 2-4)
- Third-party upgraded (POM glass-fiber reinforced): $8-15 each
Tools
None. The adjuster literally clips in by hand.
Steps
- Pull the upper rack all the way out. Keep pulling until it stops — the stop-clip is designed to release here.
- Lift the rack straight up off the rails. It just lifts off.
- Find the broken adjuster. It's at the back corner on each rail — a plastic wheel with gear teeth on top.
- Rotate the adjuster downward (toward the floor). It unlocks from its track. Pull it off the rail.
- Clip the new adjuster onto the rail in the same downward orientation.
- Rotate up until it clicks. The teeth should mesh with the rail.
- Replace the rack. Line up both sides, lower it onto the rails, test by sliding in and out.
Why "Upgraded Material" Matters
The OEM part is PA66 nylon. When you load heavy casserole dishes on the upper rack, the plastic flexes repeatedly and develops micro-cracks. We recommend buying the POM + glass fiber reinforced version — 2-3× the tensile strength, and it costs the same.
Still Not Working?
- If the rack still sags on one side, the rail itself may be bent. That's a $40-80 fix.
- If the adjuster won't stay clipped, make sure you're rotating it fully (it needs to click).
