Dishes and glasses in the upper rack come out dirty or with food residue due to a cracked, blocked, or non-rotating spray arm.
The upper spray arm is stuck, jammed, or spins unevenly, preventing proper water distribution during the wash cycle.
A damaged or cracked upper spray arm can cause water to spray in unintended directions, leading to leaks inside the tub.
A loose, broken, or warped spray arm rattles or knocks against the rack or tub during operation.
Poor rinse coverage from a failing upper spray arm leaves water residue on dishes, reducing drying effectiveness.
💡 Pro Tip: Is Your Upper Spray Arm the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Dishes and glasses in the upper rack come out with food residue or film
⚠️ Spray arm is cracked, chipped, or physically broken
⚠️ Arm spins unevenly or doesn't rotate freely during a cycle
⚠️ Unusual rattling or knocking noise during the wash cycle
🔍 Before replacing: pull the upper rack out and spin the arm by hand — it should rotate smoothly with no wobble. Check the spray nozzles for lime/calcium buildup; soak in white vinegar for 30 min first. If cleaning doesn't restore performance, replace the arm.
