Understanding the Problem
What this part is and why it matters: The Whirlpool W10712394 is an upper rack adjuster kit (also called a rack stop/adjuster). It attaches to the upper rack and rides in the dishwasher side rails to keep the rack level and captured. When the plastic adjuster is broken, the rack can fall out of the track, sag on one side, bind or not slide smoothly. Step-by-step diagnostic and repair steps: 1) Confirm the symptom: Pull the upper rack fully forward and inspect both left and right adjusters where they engage the side rails. Look for cracked/broken plastic, missing tabs, or an adjuster that spins freely. If one side is damaged the rack will tilt or pop out on that side. 2) Gather tools and parts: New adjuster kit W10712394 (or W10712395 as the compatible variant), flat screwdriver, Phillips screwdriver or nutdriver (depending on your model), pliers, and work gloves. Typically no speciality tools are required. 3) Power & safety: Turn off power to the dishwasher at the circuit breaker for peace of mind (dishwashers are connected to household power). You do not usually need to shut off the water for this repair. Wear gloves to protect your hands from sharp edges. 4) Remove the upper rack: Slide the rack out to its full extension. Depending on your model, release the rack stops or lift the rack slightly to remove the rollers from the rail. Some models have plastic tabs at the rails you push to release; others require depressing a clip. 5) Remove the damaged adjuster: Locate the broken adjuster on the end of the rack. Most adjusters snap into the rack arm or are held by a single screw/clip. Use a flat screwdriver or pliers to pry the old adjuster out or remove its retaining screw. Keep track of any small clips or screws. 6) Install the new adjuster (W10712394): Position the new adjuster into the rack arm and snap it into place until it locks. If a screw was used, reinstall and tighten snugly — do not overtighten plastic screws. Ensure the adjuster tab that engages the rail is oriented correctly (mirror image for left vs. right sides). 7) Reinstall the upper rack: Place the rollers back onto the side rails and slide the rack in and out to ensure smooth engagement. Some models require compressing a spring clip or reinstalling rail stops; make sure those are reinstalled properly. 8) Test under load: Load a few dishes or apply light downward pressure while sliding the rack in and out to confirm the rack remains level and does not pop out. 9) Final check: Run one short/no-heat rinse cycle empty to ensure there are no unusual noises and the rack stays put. Safety note: Always disconnect power at the breaker before working on electrical appliances and avoid placing fingers near edge cuts or sharp metal inside the cabinet. If the rails or rollers are severely worn or the rack itself is bent, replace those parts as well — new adjusters won’t fully fix a bent rack or damaged rail.

Helpful Repair Tip
Visually inspect both adjusters. If one side is broken, replace both sides (left & right) at the same time — matched new parts prevent uneven wear and make installation easier.
Frequently Asked Questions
Can I replace just the broken adjuster or do I need to replace both sides?
You can replace only the broken adjuster and the rack will usually work, but it’s best practice to replace both sides at the same time. Replacing both prevents uneven wear and ensures the rack stays level and aligned.
How long does this repair take and do I need a technician?
This is a quick DIY repair that typically takes 10–30 minutes. No special tools or technician are required for most models. If the rack rails or rollers are damaged or you’re not comfortable working with the appliance, hire a qualified technician.
