The lower spray arm rotates and sprays water to clean dishes in the lower rack. A cracked, clogged, or non-spinning arm causes poor wash results — replace it to restore full cleaning performance.
A damaged or improperly seated lower spray arm can cause water to spray outside the intended path, resulting in leaks from the bottom of the tub during the wash cycle.
A warped, cracked, or obstructed spray arm that drags against the tub or lower rack will produce rattling or knocking sounds. Replacing the arm eliminates the noise source.
Mineral deposits, food debris, or physical damage can seize the spray arm bearing, preventing rotation. A non-spinning arm fails to distribute water and must be replaced for proper dishwasher function.





💡 Pro Tip: How to Know Your Lower Spray Arm Needs Replacing
Your part is likely the culprit if you notice any of the following:
⚠️ Dishes in the lower rack come out dirty or with food residue after a full cycle
⚠️ Unusual rattling or knocking noise during the wash cycle
⚠️ Water pooling or leaking from the bottom of the tub during operation
⚠️ Spray arm is visibly cracked, warped, melted, or fails to spin freely by hand
🔍 Quick Check: Pull out the lower rack and spin the arm by hand — it should rotate smoothly with no wobble or resistance. If it sticks, drags, or has visible cracks, replace it now before internal clogging reduces water pressure further.
