Possible Causes

Failed internal shaft seal, Cracked disposal housing, Corroded grinding chamber, Loose dishwasher inlet or discharge gasket

How to Fix / Troubleshooting

Safety first: Turn off power and do not continue using a disposal that leaks from the body; water can reach electrical components.

  • Identify leak location: Run a small amount of water and observe carefully with a flashlight to see if the leak is from the dishwasher inlet, discharge connection, or the body itself.
  • Check hose connections: Tighten the dishwasher inlet clamp and discharge pipe connections. Replace any worn rubber gaskets.
  • Body leak assessment: If water seeps from seams in the metal or plastic housing, the internal seals or chamber are compromised.
  • Do not attempt internal resealing: Internal leaks are not reliably repairable in most disposals.

For leaks from the body or shaft area, replacement of the entire Maxmatic disposal unit is the recommended solution.
