Why is my dishwasher spray arm not spinning?

The spray arm might be clogged with food debris, obstructed by dishes, or have a worn-out bearing or mounting hub. Inspect for blockages and ensure dishes are not interfering with its rotation. If the arm is damaged or the bearing is faulty, replacement is typically needed.

Can I clean a clogged dishwasher spray arm?

Yes, you can often clean a clogged spray arm. Remove it from the dishwasher and clear any debris from the spray holes using a toothpick or small brush. Rinse it thoroughly under running water to ensure all blockages are removed. Check for mineral buildup and use vinegar if necessary.

How often should a dishwasher spray arm be replaced?

A dishwasher spray arm typically does not require routine replacement unless it shows signs of damage, such as cracks, holes, or if it stops rotating effectively. With proper care and occasional cleaning, it can last for many years.
