The GE APPLIANCES WD12X10304 is a rack slide end cap designed as a direct OEM replacement component for GE dishwasher rack assemblies. This small but essential part caps the end of the dish rack slide rail, preventing the rack from disengaging from its track during normal operation. It protects the slide mechanism from wear and keeps the rack rolling smoothly inside the dishwasher tub. Installation is typically handled by appliance service technicians or experienced DIYers during routine maintenance or rack repair work.
This end cap is suited for residential dishwasher applications where the original rack slide end cap has broken, cracked, or gone missing. It is sold as a single unit, making it straightforward to replace one damaged cap without purchasing a full rack assembly. Refer to your dishwasher model documentation to confirm this part number fits your specific unit before ordering.
Designed as an OEM-style replacement rack slide end cap for compatible GE dishwasher models. Verify fitment against your appliance model number before installation.
Disconnect power to the dishwasher at the breaker or by unplugging the unit before beginning any service work. Remove the dish rack fully from the tub to access the slide rail end. The end cap typically snaps or presses onto the rail end without special tools. Confirm the replacement cap is fully seated before returning the rack to service.
