When to Replace a Spray Arm
These points help you choose the best dishwasher detergent replacement heads.
Signs of a bad spray arm
Dirty dishes on one rack, an arm that will not spin, or cracks along the arm all point to a replacement.
Clean the holes first
Hard water and food can block spray holes. Clear them with a toothpick before buying a new arm.
Find your model number
Dishwasher parts are model-specific. Look for the label on the edge of the door or the side of the tub, and match the part number on your old part.
Genuine vs. third-party parts
Genuine OEM parts guarantee fit. Third-party parts cost less and many fit well, but read recent reviews for your exact model.
How parts affect detergent performance
A worn filter, cracked spray arm or stuck dispenser lid stops detergent reaching your dishes. Fixing the part often fixes the cleaning problem.
Spray Arm Check Steps
Check your spray arms monthly:
- Spin each arm by hand.
- Look for cracks and warping.
- Clear blocked holes.
- Make sure tall items do not block it.
