Understanding the Problem
What W10350375 is and why it matters: W10350375 is a replacement part used in Whirlpool-family dishwashers as part of the upper rack rail/roller assembly (often sold in kits with W10712395, W10250159 or AP5957560). It supports and guides the dishwasher's upper rack so it slides smoothly in and out. When the rail or rollers fail the upper rack can stick, come off the track, sag, or fall out completely. Step-by-step diagnostic and repair instructions: 1) Confirm the symptom: Pull the upper rack most of the way out — does it bind, scrape, sag, jump off the track, or fall out? Look for broken plastic, missing rollers, or a cracked rail. Check both left and right rails and both sets of rollers. 2) Power & safety: Turn off power to the dishwasher at the circuit breaker. You don't usually need to disconnect water to replace a rack rail, but turn off the water supply if you plan to move the appliance. 3) Remove the upper rack: Slide the rack out to the stop position. Locate the rack stops/retainers on each side (plastic clips or end caps). Depending on model, depress tabs or lift up the wheel assembly to clear the stops and slide the rack off the rails. 4) Inspect parts: With the rack removed, inspect the rails, rollers, axle pins and any clips. If rollers are cracked, missing, or the rail track is bent/cracked, replacement is needed. W10350375 is used where the rail or roller assembly is damaged. 5) Remove old rail/roller assembly: Most rail kits use plastic clips or screws. Remove any screws or release the snap-in clips and slide the old rail / roller out. Keep track of small pins or clips. 6) Install new rail/roller kit (W10350375 or full kit AP5957560/W10712395): Align the new rail with the mounting points. Snap or screw it into place. Install new rollers onto their axles and ensure they seat properly in the track. Replace any end caps or stops included in the kit. 7) Reinstall the upper rack: Slide the rack back onto the rails, aligning wheels with track grooves. Push the rack all the way in and out a few times to confirm smooth travel and correct engagement of stops. 8) Test: Restore power and run an empty short cycle to confirm there is no interference and the rack stays in place. Check for unusual noises or rubbing. 9) Final check & adjustments: If the rack still catches, verify that the rollers are seated and the rail is correctly positioned. Some models allow minor vertical adjustment of the rail or use an adjustment lever on the rack itself. Safety note: Always shut off electrical power at the breaker before working on the dishwasher to avoid shock. Take care when handling sharp edges inside the cavity. If the dishwasher must be pulled out, secure quick-connects and follow manufacturer guidance to avoid damaging water lines.

Helpful Repair Tip
Visually inspect the roller wheels and plastic rail for hairline cracks or missing pieces — if a roller is chipped or the rail has worn grooves, replace the entire rail/roller kit (W10350375/AP5957560) rather than just one wheel.
Frequently Asked Questions
Can I replace just one roller or do I need the whole kit?
If only one roller is damaged you can replace just that wheel if you can find the exact roller part and axle. However, if the rail is worn or other rollers show wear it's better to replace the whole rail/roller kit (W10350375/AP5957560) to ensure smooth operation and avoid repeated repairs.
How long does it take to replace the upper rack rail/roller kit?
Replacement is typically 20–45 minutes for a DIYer with basic tools: remove the rack, change the rail/rollers, and reinstall the rack. If you need to pull the dishwasher out or disconnect lines, allow extra time. Always disconnect power first.
