Whirlpool & KitchenAid Dishwasher Upper Rack Adjuster Parts — Models & Compatibility

If your dishwasher's upper rack won't stay in position, drops unexpectedly, or the height adjustment mechanism has failed, you're likely dealing with worn rack adjusters. This W10350375 kit fixes the most common upper rack issues across Whirlpool, KitchenAid, and Kenmore dishwashers — from the WDT series to KDFE models. This complete adjuster kit includes everything needed for both left and right sides, and it's the updated, more durable design that Whirlpool now specifies as the proper replacement.

Is This the Right Part for Your Model?

This upper rack adjuster kit fits over 200 Whirlpool-manufactured dishwasher models. Your model number is typically located on the door frame (visible when you open the door) or on the inside edge of the tub. Common compatible models include WDT750SAHZ0, WDTA50SAHZ0, WDT730PAHZ0, WDT780SAEM series, WDT970SAHZ0, and KitchenAid KDFE454CSS4, KUDC10IBSS0, KUDC10FBWH0, KUDE20FBWH0, KUDC10IBBL0, and KUDE20FBBL series.

About This Replacement Part

The W10350375 is a complete adjuster kit that replaces older part numbers W10712395, AP5957560, W10250159, and PS10065979. What makes this repair tricky is that you can't buy individual roller assemblies — if the spoke that holds the wheel breaks (a common failure), you'll need this complete kit. The good news? This updated design addresses the weak points in the original adjusters. You're getting both left and right adjuster assemblies plus the actuator mechanisms that control rack height. The kit requires assembly, and the finished product will look different from your original parts, but it's engineered to be more durable than what came with your dishwasher.

Common Symptoms This Part Fixes

Upper rack adjuster failures show up in several ways. The most obvious is when the rack won't stay at the height you set — it drops down unexpectedly or won't lock into position. You might hear excessive noise during wash cycles as the rack shifts around. In some cases, the door won't close properly because the misaligned rack interferes with the door mechanism. Less obvious is when dishes don't get clean — if the upper rack has dropped or tilted, spray arm coverage changes and you'll see spotting or food residue on glasses and plates. Some owners also report leaking issues tied to rack misalignment affecting the door seal.

What's Included in This Kit

You're getting a complete solution here: two rack adjusters (one for each side), two adjuster actuators (the mechanisms that let you raise and lower the rack), and all necessary hardware. The parts come unassembled, so you'll need to put the adjusters together before installation. The updated design means your finished adjusters will look different from the originals — don't let that throw you. They're specifically engineered to be stronger where the old ones typically failed.

Installation Overview

This isn't a plug-and-play swap. You'll need to remove the upper rack completely, disassemble the old adjuster mechanisms from both sides, assemble the new adjuster components, and then install them onto the rack. The assembly step is where most people get confused — the parts don't look like the originals, and you're building them from scratch. Take photos of your old adjusters before removal so you understand the final orientation. Most experienced DIYers complete this repair in 30-45 minutes once they understand how the new parts go together.

Verify Your Model Compatibility

This kit works across multiple Whirlpool brands, but always verify your specific model number before ordering. Compatible models include the WDT750, WDTA50, WDT730, WDT780, WDT970, WDT910 series from Whirlpool, plus KitchenAid KDFE, KUDC, and KUDE series. If you have a Kenmore dishwasher manufactured by Whirlpool (model numbers typically starting with 665), this kit likely fits, but cross-reference your complete model number to be certain.
