InSinkErator Dynamic Internal Leak Under Pressure

Disposal runs but water leaks from around the reset button area only when the unit is running

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Cracked lower housing near reset button, Failed internal seal allowing water to reach motor base, Overpressure from blocked discharge forcing water through weak point

How to Fix / Troubleshooting

Safety first: Turn off power and do not operate the disposal while it is leaking.

Check for discharge blockage: Inspect and clear the discharge elbow, P-trap, and downstream piping to ensure water can exit freely.
Retest briefly: If safe, restore power and run water with a short test. If water still leaks from the reset area, the internal housing is compromised.
Replace unit: Internal leaks at the reset button indicate failure of the sealed grind chamber. Replace the entire disposal.
