Is it time to replace?

• Common Symptoms: Poor cleaning on the lower rack, weak spray action, or dishes that come out with residue.
• Visible/Sensory Cues: Cracked spray arm body, clogged spray holes, worn hub area, or an arm that no longer spins freely.

Pro Tip: Clean the filter and feed area while replacing the spray arm. Restricted water flow can mimic spray-arm failure and reduce the performance of the new part.
