Why is my dishwasher spray arm not spinning?

A spray arm may stop spinning due to clogs in the spray holes, a worn-out bearing, or a broken mounting hub. Food debris or mineral buildup can restrict water flow, preventing rotation. Inspect the spray arm for blockages and check its connection point for damage or wear.

Can I repair a broken dishwasher spray arm?

In most cases, a broken or cracked spray arm needs to be replaced rather than repaired. Attempting to patch cracks may not withstand the water pressure and heat, leading to leaks or inefficient cleaning. Replacement ensures proper function and longevity.

How do I know if I have the right replacement spray arm?

Verify compatibility by checking your dishwasher's model number against the part's specifications. Visually compare the new part with the old one for matching mounting styles and dimensions.
