Quick answer: A Whirlpool dishwasher upper rack that drops, tilts, or won't stay at adjusted height has broken adjuster wheels or worn cam slides. The fix is the upper rack adjuster kit (OEM W10712394 left or W10712395 right) — $50, 15-minute install.
>
Most likely culprit: Cracked plastic adjuster cam (90% of cases).
Time to fix: 15-20 minutes.
Difficulty: Easy — no tools needed for most models.
If your Whirlpool dishwasher upper rack droops, tilts unevenly, or rolls out when loaded, the adjuster mechanism on one or both sides has failed. This is one of the most common Whirlpool dishwasher issues and the easiest to fix.
Cause 1 — Adjuster cam cracked (90%)
The plastic adjuster mechanism uses small cam wheels and slides to set rack height. After 5-8 years of heat cycles + dish weight, the plastic fatigues and cracks. Symptoms: rack on one side drops lower than the other, or whole rack falls when pulled out.
How to confirm:
- Pull upper rack fully out.
- Inspect both side adjusters (where rack rails meet the rack frame).
- Look for: cracked plastic, missing wheels, sloppy movement.
- Compare both sides — typically the side that drops is the failed one.
The fix: Replace adjuster on failing side. OEM W10712394 (left side) or W10712395 (right side). Typical price $45-60 per side. Difficulty: Easy — 15 min, no tools.

Cause 2 — Both sides worn (8%)
If one side broke from age, the other is likely close behind. Replacing only one means the other will fail in months.
How to confirm: If failed adjuster is 5+ years old, presume both sides are degraded.
The fix: Replace both adjusters preventively. $90-120 total. Same 15-min install per side.
Cause 3 — Upper rack rail damage (2%)
Rare — the rail itself breaks where adjuster connects. Usually only after the adjuster has been cracked for months and stresses the rail.
The fix: Replace upper rack rail (OEM varies, typically $30-50). Difficulty: Easy — 20 min.

How to identify left vs right adjuster
Stand IN FRONT of dishwasher facing it. The adjuster on YOUR LEFT = "left side" = W10712394. Right = W10712395.
If unsure, order both — they're often a matched pair anyway.
How to install (general steps)
- Pull upper rack fully out, then lift slightly to disengage from rails.
- Remove rack to a flat surface.
- Pop off old adjuster (clips/snaps).
- Snap new adjuster in same orientation.
- Slide rack back onto rails.
- Test by adjusting up/down — should click into 2-3 height positions firmly.
Frequently asked questions
Q: Can I just glue the broken plastic?
A: Temporary fix only. Plastic-to-plastic glue fails within days under wash cycle heat (140°F+). Replacement is $50 — not worth gluing.
Q: My rack falls only when loaded with dishes. Adjuster issue or different?
A: Adjuster. When unloaded, the cracked plastic still holds light weight; loaded weight exceeds capacity → drops.
Q: Does Whirlpool sell these adjusters direct?
A: Yes via Whirlpool service site, but at MSRP $65-75. Same OEM part on certified reseller (us, Repair Clinic, Amazon) = $45-60.
Q: How long should adjusters last?
A: 6-10 years. Premium models last longer; budget models 4-6 years.
Q: My dishwasher is 3 years old and adjuster failed. Warranty?
A: Standard Whirlpool warranty is 1 year. After year 1 = DIY or service. Some retailers offer 3-5 year extended warranty — check your purchase receipt.
Q: Can I delay this fix?
A: Short-term yes — but a falling rack will damage glassware and may bend the rail (turning $50 fix into $200 fix). Replace within a month.
