LG Dishwasher Upper Spray Arm / Nozzle Assembly (Water Feed Tube Spinner) 5249DD2001A, Replaces 5249DD2001B, 5249DD2001D

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Upper spray arm does not rotate freely
• Poor cleaning concentrated on the upper rack
• Visible food particles or mineral buildup blocking spray openings
• Cracked, broken, detached, or damaged upper spray arm/nozzle
• Possible spray-arm noise if the assembly is damaged or obstructed

Check Before Replacing

• With the dishwasher empty and power off, inspect the upper spray arm/nozzle for cracks, separation, deformation, or trapped debris.
• Check that the spray openings are not blocked; rinse the removed assembly with water and remove visible food particles with a suitable fine-point tool.
• After reinstalling, gently rotate the upper spray arm by hand to confirm that it turns freely.
• Verify that the upper spray arm is properly seated and locked, and that no dish or utensil obstructs its path.
• If cleaning performance is poor, inspect the spray arm before concluding that it is defective because loading, water supply, filters, and other components can also affect wash results.
