KitchenAid Dishwasher Upper Rack Adjuster Parts — Models & Compatibility

The upper rack adjuster (W10546503) is what lets you raise and lower your KitchenAid dishwasher's top rack to fit tall items. When these plastic clips crack or break — usually from years of daily use — you'll hear rattling during wash cycles, the rack won't stay in position, or the door won't close properly because the rack's sitting crooked. This hub covers compatible models across KitchenAid's KDFE, KDTE, and KDTM series dishwashers.

Is This the Right Part for Your Model?

Check your dishwasher's model number on the door frame — open the door and look along the top edge or side. You need the complete model number including any letter suffixes (like KDTE334GPS0 or KDFE104DSS4). This adjuster fits most KitchenAid built-in dishwashers from 2012-present, but verifying your exact model prevents ordering the wrong part.

About This Replacement Part

Part number W10546503 replaces older versions WPW10546503, W10418314, and W10306646 — they're all functionally identical. The adjuster clips onto the rack's side rails and engages with the adjustment track inside the tub. Common failure symptoms include the door refusing to latch (because the misaligned rack blocks it), rattling or banging noises during operation, water leaking from the door seal, and dishes coming out dirty because spray arms can't reach properly positioned dishes. You'll typically replace both left and right adjusters at the same time since they wear at similar rates.

Installation Overview

You don't need to disconnect power or water — just pull out the upper rack completely. The old adjusters slide off the rack rails once you press the release tab. Snap the new ones onto both sides, making sure they click into place. Slide the rack back in and test the height adjustment to confirm they're engaging properly with the tracks.

Why This Part Fails

Dishwasher racks move in and out thousands of times over their lifespan. The plastic adjuster clips take constant stress from the weight of dishes plus the force of spray arms hitting loaded items. Hard water deposits can also build up in the adjustment tracks, making the mechanism stick and putting extra strain on the plastic. Eventually the clip teeth wear down or the housing cracks, and the rack stops staying in position.
