Possible Causes

Removed or damaged sink baffle, Incorrect or non-InSinkErator splash guard installed, High water flow directly into chamber, Overloading with food at once

How to Fix / Troubleshooting

Safety first: Turn off the disposal before touching the splash area.

  • Check splash guard: Verify that the InSinkErator sink baffle or Quiet Collar® splash guard is installed and seated properly in the sink flange.
  • Replace if worn: If the rubber is stiff, torn, or deformed, replace it with a genuine InSinkErator splash guard designed for your model.
  • Adjust water flow: Use a moderate, steady stream of water instead of a high-pressure jet directly into the opening.
  • Feed gradually: Avoid dumping large quantities of food at once; feed small amounts to reduce splash.
