A worn or clogged chopper restricts water flow to the circulation pump, causing weak spray arm pressure. Replacing the chopper assembly restores full pump performance and cleaning power to both racks.
A broken chopper blade or snapped drive shaft creates grinding, rattling, or humming sounds at the start of each wash cycle. A new chopper assembly eliminates the noise immediately.
Unchopped food debris accumulates and clogs the chopper screen, blocking the drain path. Replacing the chopper assembly clears the restriction and restores normal drainage.
A clogged chopper screen severely reduces water reaching the circulation pump impeller, starving both upper and lower spray arms. A new assembly fully restores spray arm water pressure.
A failed chopper allows food particles to accumulate in the sump area, leading to foul odors and dirty wash water recirculating onto dishes. Replacing the chopper assembly resolves the root cause.
💡 Pro Tip: Is Your Dishwasher Chopper the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Dishes not getting clean — upper or lower spray arms barely spraying
⚠️ Loud grinding, rattling, or humming noise at the start of the wash cycle
⚠️ Dishwasher not draining or draining very slowly
⚠️ Visible food debris or slimy buildup clogging the chopper screen
🔍 Diagnostic tip: Pull out the lower rack and remove the spray arm. Look through the sump cover grille — if the chopper blade spins freely with no resistance or you can see a snapped drive shaft, the chopper assembly needs replacement. Pro move: replace the drain check valve at the same time to ensure full drain performance.
