When Your Disposal Isn’t Working Right
A garbage disposal that hums but doesn’t spin, leaks from underneath the sink, or has stopped working entirely is one of the more common kitchen plumbing frustrations. Often the issue is a jam or a tripped reset button, but leaks and persistent motor issues typically need a closer look.
Before calling for service, it’s always worth checking whether the reset button (usually a small red button on the bottom of the unit) has tripped — that alone resolves many “dead” disposal complaints.
Common Garbage Disposal Problems
- Humming but not spinning — usually a jam; never put your hand inside, use the manufacturer’s tool
- Leaking from underneath — often a worn seal or loose connection
- No power at all — could be a tripped reset button, a bad outlet, or a failed motor
- Excessive noise or vibration — may indicate a loose mounting or damaged impellers
How Repairs Typically Go
Your plumber will start by checking the basics — the reset button, power connection, and whether the unit is jammed — before moving to a deeper diagnosis. A jam is usually cleared using a hex wrench inserted into the bottom of the unit to manually free the impellers, a far safer approach than reaching into the disposal by hand.
If the issue is a leak, your plumber will identify whether it’s coming from the sink flange, the dishwasher connection, or the discharge pipe, then replace the specific worn seal or fitting causing it. For units with a failed motor or extensive internal wear, replacement is often more cost-effective than repair, and your plumber will let you know if that’s the better path for your situation.
