Possible Causes

Loose dishwasher hose clamp, Cracked dishwasher inlet nipple, Missing or damaged dishwasher inlet gasket, Dishwasher knockout plug not fully removed

How to Fix / Troubleshooting

Safety first: Turn off power and do not run the dishwasher until the leak is fixed.

  • Inspect hose connection: Locate the small hose from the dishwasher attached to the side of the disposal. Check that the clamp is tight and the hose is fully seated.
  • Tighten or replace clamp: Use a screwdriver or nut driver to snug the clamp. Replace with a new worm-gear clamp if the original is weak or rusted.
  • Check for cracks: If water seeps from the plastic nipple itself, the disposal housing is cracked and the unit must be replaced.
  • Verify knockout removal (new installs): If the dishwasher is not draining, remove the hose and confirm the internal knockout plug in the Project Source dishwasher inlet was fully punched out during installation. Use a screwdriver and hammer to knock it out, then remove the plastic piece from inside the grinding chamber.
