Is it time to replace?

• Common Symptoms: Poor cleaning results, weak spray action, or residue left on dishes in the affected wash zone.
• Visible/Sensory Cues: Cracked spray arm body, blocked spray holes, worn hub, or an arm that no longer rotates freely.

Pro Tip: Inspect the water feed connection and support points while the arm is removed. Restricted water flow can reduce the benefit of the replacement arm.
