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.
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.
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.
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.
