Check Before Replacing

• With power disconnected, inspect the upper wash arm for cracks, warping, blocked spray openings, or food/mineral debris.
• Manually rotate the installed arm to check for free movement and interference from the rack or dishes.
• Remove the arm only as directed for the specific dishwasher model and rinse or visually inspect the spray openings; do not enlarge the openings.
