How to Fix KitchenAid Dishwasher Upper Rack Adjusters (W10350376)

The upper rack adjusters on KitchenAid dishwashers allow you to raise or lower the top rack to accommodate tall items on either level. When these adjusters wear out or break, the rack sags on one or both sides, rides unevenly on the rails, or gets stuck and will not adjust at all. Part number W10350376 is the replacement adjuster used across most KitchenAid and Whirlpool dishwashers since this is a shared-platform component.

This is one of the most common repairs on KitchenAid dishwashers because the adjuster mechanism bears the weight of a loaded upper rack through thousands of load/unload cycles. The plastic clip and wheel assembly wears, cracks, or strips the adjustment teeth after 4-7 years of daily use. Models with the FreeFlex third rack add extra weight above, accelerating adjuster wear.

Before You Start

• Tools needed: No tools required for most models (hand removal). 5/16" nut driver if your model has rack track screws. Flat screwdriver for prying stuck clips
• Parts needed: Upper rack adjuster W10350376 — sold in pairs (~$15-$30 per pair). Replace both sides even if only one is broken to prevent uneven wear
• Time required: 15-25 minutes
• Difficulty: Beginner
• Safety warning: No electrical disconnection required for this repair. The rack and adjusters are inside the tub and accessible with the door open. However, avoid running the dishwasher with a sagging rack as the spray arm below can contact dishes and cause damage.

Symptoms of Failed Rack Adjusters

• Upper rack tilts to one side when loaded
• Rack slides unevenly or binds when pulling out
• Clicking or grinding sound when adjusting rack height
• Rack drops down unexpectedly during use
• Adjustment lever does not lock into position
• Wheels on the rack guides are cracked or flat-spotted
• Water pooling on upper rack items (rack too low, blocking spray pattern)

Step-by-Step Instructions

Step 1: Remove the Upper Rack

Pull the upper rack out fully until it stops on the rail stops. Locate the stop clips or tabs at the end of each rail (one per side). On KitchenAid models, squeeze the blue or gray tabs while pushing the rack past the stops. With both tabs released, slide the rack completely out of the tub and set it on a counter or towel.

Step 2: Identify Your Adjuster Type

KitchenAid uses two adjuster designs:

• Clip-on adjusters (most common): Plastic assemblies that clip onto the rack rail ends. They have a lever you lift to adjust height and lock into teeth on the tub wall track
• Integrated rail adjusters: Built into the rack rail with wheels that ride in the tub wall track. Less common on KitchenAid, more typical of compact European models

For clip-on adjusters (W10350376 type): proceed to step 3. For integrated rail type: the entire rail assembly replaces as a unit.

Step 3: Remove the Old Adjuster

With the rack removed, locate where the adjuster clips onto the end of the rack rail. There is typically a locking tab you depress or a clip you squeeze to release the adjuster from the rail end. On the W10350376 design, push the release tab with your thumb and slide the adjuster off the rail end. If it is stuck from mineral deposits, use a flat screwdriver to gently pry the locking tab while pulling the adjuster off.

Step 4: Clean the Rack Rail End

With the old adjuster removed, inspect the rack rail end. Clean any mineral deposits or debris from the mounting area. The new adjuster needs to clip on cleanly. If the rail end is bent or corroded, gently straighten it with pliers. A deformed rail end prevents the new adjuster from locking properly.

Step 5: Clean the Tub Wall Tracks

Inside the dishwasher tub, inspect the vertical tracks on both side walls where the adjuster engages. These have teeth or notches for the height-adjustment mechanism. Clean any mineral buildup from the teeth using a toothbrush and white vinegar. Clogged teeth prevent the adjuster from locking at the selected height.

Step 6: Install the New Adjusters

Slide the new adjuster onto the rack rail end until the locking tab clicks into place. Verify it is seated fully and does not wobble. Test the height-adjustment lever: lift it and the adjuster should slide freely along the track when you reinstall the rack. Release the lever and it should lock firmly.

Install the second new adjuster on the opposite rail end (always replace as a pair).

Step 7: Reinstall the Upper Rack

Align the rack wheels/adjusters with the tub wall tracks. Slide the rack into the tracks from the front. Push it all the way in until the stop tabs engage. Pull it back out to verify smooth operation. The rack should glide evenly without tilting.

Step 8: Set the Desired Height

With the rack installed, lift both adjustment levers simultaneously and raise or lower the rack to your preferred position. Release the levers and verify both sides lock at the same height. Load the rack with dishes and confirm it holds level under weight.

Dealing with the FreeFlex Third Rack

KitchenAid models with the FreeFlex third rack (2022 and newer) place additional weight above the upper rack. The third rack has its own independent rail system, but its weight transfers through the upper rack when fully loaded. If you have a FreeFlex model:

• The upper rack adjusters bear more stress. Consider replacing every 3-4 years proactively
• When removing the upper rack for adjuster replacement, also remove the third rack first. Slide it out using the same tab-release method
• Verify the third rack spray tube connection is not interfering with upper rack adjustment after reinstalling

Troubleshooting After Replacement

• If the rack still tilts after new adjusters, check that both are set to the same height position. Count the tooth notches from top on each side to confirm they match
• If the adjuster lever does not lock, the tub wall track may have worn teeth. Inspect the track for stripped or broken notches. Track replacement requires removing the inner tub panels (professional repair recommended)
• Grinding noise during adjustment means debris between the adjuster and track. Remove the rack, clean tracks thoroughly, and reinstall
• If the new adjuster feels loose on the rail end, the rail itself may be worn. A small amount of clear silicone on the rail end before clipping on the adjuster provides a tighter fit

When to Call a Professional

• If the tub wall tracks are damaged (stripped teeth, bent track), the tub inner panel needs replacement which requires substantial disassembly
• If the rack rail itself is bent or corroded to the point where adjusters cannot grip properly, the entire rack assembly needs replacement ($80-$150)
• If the rack falls during a cycle causing spray arm damage, both components need assessment

FAQ

Q: Are KitchenAid upper rack adjusters the same as Whirlpool? A: Yes. Part W10350376 is a cross-brand Whirlpool Corporation component. The same adjuster works in KitchenAid, Whirlpool, and Kenmore dishwashers built on the shared platform. Order whichever brand version is cheapest or most available.

Q: Why does my upper rack keep falling to the lowest position? A: The locking teeth in the adjuster mechanism are stripped or the lever spring is broken. Once the lock mechanism fails, the adjuster cannot hold the rack at any raised position. The weight of loaded dishes pulls it down. Replace the adjusters to restore locking function.

Q: Should I replace one adjuster or both? A: Always replace both sides simultaneously. Adjusters wear at similar rates, and a new adjuster on one side with a worn one on the other creates uneven rack height. The cost difference is minimal (they are sold in pairs for this reason).

Q: My KitchenAid FreeFlex third rack is hard to slide. Is that the adjusters? A: No, the FreeFlex third rack has its own independent rail system separate from the upper rack adjusters. If the third rack is stiff, its own rail wheels or track need cleaning. Remove the third rack and clean the rail channels with a damp cloth.
