Whirlpool Dishwasher Upper Rack Adjuster/Roller Replacement — What This Part Does
The upper rack adjuster and roller assembly lets you raise, lower, and slide the top dishrack in and out on the rails. The adjuster housing holds the wheel or roller that rides the track, and on height-adjustable models it includes a lever, clip, and locking tab to set the rack position. The part is plastic and sits in a wet, detergent-filled environment, so repeated use and heat cycling crack the housing, break the locking tabs, or deform the wheels.
Whirlpool redesigned the adjuster kit on some models because the original version wore out or broke frequently. When the adjuster or roller fails, the rack binds on the rail, drops to one side, or won’t stay at the height you select. Replacing the adjuster or roller assembly on both sides of the rack restores smooth travel and level positioning.
Signs It Needs Replacing
- Upper rack is hard to pull out or push in The rack binds, jerks, or sticks when you try to slide it on the rails.
- Rack drops or tilts to one side One corner of the rack sags or won’t stay level during the wash cycle.
- Height adjuster won’t lock or stay in position You set the rack height but it drops back down or won’t hold the selected level.
- Visible cracks, missing tabs, or broken wheels The adjuster housing is cracked, the locking tab is snapped off, or the roller wheel is deformed or missing.
- Rack slides too far and falls off the rails The end cap or adjuster is broken so the rack pulls completely out of the tracks.
- Loud grinding or scraping noise when moving the rack A damaged roller or wheel drags on the rail instead of rolling smoothly.
How to Replace It
- Unplug the dishwasher or switch off the breaker at the panel.
- Pull the upper rack out as far as it will go, then locate and remove the end caps or stops on each side of the rack so you can fully pull the rack out of the tub rails.
- Lift the rack out of the dishwasher and set it on a clean work surface.
- Inspect both sides of the rack for the adjuster housing, roller or wheel assembly, locking tabs, and clips to identify which side is broken or worn.
- Press or squeeze the locking tab or clip on the failed adjuster and rotate or tilt the assembly to release it from the rack frame (some designs slide out, others pivot and lift free).
- Position the new adjuster or roller assembly on the rack, making sure left and right orientations match if the part is sided, then snap or lock the tabs fully into place.
- Repeat on the opposite side if both adjusters or rollers are worn or if you are replacing both as a set.
- Slide the rack back onto the tub rails, confirm it moves smoothly and stays level, then reinstall the end caps or stops to prevent the rack from pulling out too far.
- Restore power and run a short test cycle or slide the rack in and out several times to verify smooth operation and that the height adjuster locks if your model has that feature.

When to Call a Pro
This repair requires no special tools and is safe for any owner once power is off. If your rack rails inside the tub are also bent, corroded, or broken, or if the rack itself is warped or cracked beyond the adjuster replacement, a technician can assess whether you need a full upper rack assembly or additional rail hardware. Call a pro if you are uncomfortable removing the rack or if the new adjuster does not solve binding or tilting after installation, since that may point to a bent rail or tub-frame issue.
