This Part Fixes These Problems

Door Won't Latch / Close

A broken or missing rack slide end cap allows the dish rack to slide too far forward, pressing against the door and preventing it from closing or latching properly.

Rack Slides Off Track

Without the end cap stop, the rack can slide completely off the rail when pulled out, causing it to fall or become dislodged from the dishwasher.

Rack Misalignment

A cracked or worn end cap fails to hold the rack in position, resulting in the rack sitting unevenly or wobbling on the slide rail during loading and unloading.

Rack Difficult to Slide

A broken end cap can snag or catch on the rail, making it hard to smoothly slide the dish rack in and out of the dishwasher.

💡 Pro Tip: Is Your Rack Slide End Cap the Problem?

Your part is likely the culprit if you notice any of the following:

⚠️ Dish rack slides completely out of the dishwasher when pulled

⚠️ Dishwasher door won't latch or close properly — rack is pushing against the door

⚠️ Rack feels loose, wobbly, or misaligned on the slide rail

⚠️ Visible cracks, chips, or missing plastic on the end of the rack rail

🔍 Diagnosis Tip: Pull the rack out slowly and watch the end of the slide rail. If the rack drops off or the cap is visibly broken, this is your part. Check both front and rear caps — rear caps require removing the front caps and sliding the rack fully off the rail for access.

Questions & Answers

Does this end cap fit both the left and right side of the rack slide rail?
Answered by Support Team  ·  Mar 15, 2024
Yes — WD12X10304 is a universal fit. One cap can be installed on either the left or right side of the rack slide rail. You only receive one cap per order, so order two if you need to replace both sides.
My dishwasher door won't close all the way. Could the rack end cap cause this?
Answered by Support Team  ·  Nov 20, 2023
Absolutely. A broken or missing rack slide end cap allows the dish rack to slide forward too far and push against the inside of the door, preventing it from closing or latching. Replacing the WD12X10304 end cap is one of the first things to check when your dishwasher door won't stay shut.
How do I replace the rear rack slide end cap — it's harder to reach?
Answered by Support Team  ·  Jan 8, 2025
To replace a rear cap, you'll need to remove the front end caps first, then slide the entire dish rack completely off the rail. This gives you full access to the rear cap position. Snap the new cap in place, then slide the rack back on and reinstall the front caps. The whole job takes about 10 minutes.
Is this part compatible with Kenmore dishwashers?
Answered by Support Team  ·  Jul 22, 2024
Yes. WD12X10304 is compatible with select Kenmore dishwasher models including 18385, 361402891, 3631401190, 3631444597, 3631444896, 36315465790, 36316121100, and 36316129100, among others. Kenmore dishwashers in these ranges were manufactured by GE and use the same rack rail system.
What material is this end cap made from and will it hold up to heat and detergent?
Answered by Support Team  ·  Feb 10, 2026
Our WD12X10304 replacement end cap is molded from BPA-free, heat-resistant ABS plastic — the same material class used in the original GE part. It is designed to withstand repeated dishwasher cycles, hot steam, and detergent exposure without cracking, warping, or discoloring over time.
