Garbage disposals are one of the most convenient kitchen appliances—until they stop working. One day everything drains smoothly, and the next you’re dealing with strange noises, standing water, or a unit that won’t turn on at all.
The good news? Many common garbage disposal problems start small and can be fixed easily if you understand what’s going on. The bad news? Ignoring them or trying the wrong DIY fix can turn a minor issue into a flooded cabinet or damaged plumbing.
This guide breaks down the most common garbage disposal problems, what causes them, which fixes are safe to try, and when it’s time to call a professional plumber.

Common Garbage Disposal Problems Homeowners Face
Most garbage disposal issues fall into a few predictable categories. Knowing which one you’re dealing with helps you avoid guesswork—and costly mistakes.
1. Garbage Disposal Won’t Turn On
If you flip the switch and nothing happens, the problem is usually electrical, not mechanical.
Common causes include:
Many homeowners panic at this stage, but sometimes the fix is as simple as pressing the red reset button on the bottom of the unit.
A non-working garbage disposal can hide electrical or motor issues—call Dovis Plumbing at (954) 516-1078 before it leads to leaks or sink backups.
2. Garbage Disposal Is Humming but Not Grinding
A humming sound usually means the motor is running, but the blades are stuck.
This often happens when:
This is one of the most common garbage disposal problems—and one of the easiest to fix if done safely.
Important: Never put your hand inside the disposal, even if it’s turned off.
3. Slow Draining Sink with a Disposal
If water pools in your sink, the issue may not be the disposal itself—but the drain line connected to it.
Typical causes include:
Chemical drain cleaners often make this problem worse by hardening grease further down the pipe.
That’s usually a clog beyond the unit—schedule professional drain cleaning with Dovis Plumbing at (954) 516-1078 before it turns into a full blockage.
4. Garbage Disposal Leaking Under the Sink
Leaks are a red flag that shouldn’t be ignored.
Common leak points include:
If the unit itself is cracked, replacement is usually the only safe option.
5. Loud or Unusual Noises
Grinding metal, rattling, or screeching noises usually indicate something foreign inside the disposal.
Items that commonly cause noise:
Running the unit while these items are inside can damage the blades or motor.
Easy Garbage Disposal Fixes You Can Try Safely
Some garbage disposal problems can be fixed without professional help—as long as safety comes first.
Reset the Unit
Most garbage disposals have a small reset button on the bottom.
- Turn off power
- Press the reset button
- Restore power and test
If it trips again immediately, stop—there may be a deeper issue.
Free a Jammed Disposal
Use a hex (Allen) wrench in the bottom slot of the disposal to manually turn the blades back and forth. This can dislodge stuck debris safely.
Clear Minor Clogs
Avoid chemical cleaners—they damage pipes and disposal seals.
Forcing a jammed or leaking disposal causes bigger damage—call Dovis Plumbing at (954) 516-1078 for a safe, permanent solution.
What You Should NEVER Put in a Garbage Disposal
Many garbage disposal problems are preventable. These items should never go down the unit:
These materials either harden, expand, or wrap around blades—leading to clogs and motor failure.
When Garbage Disposal Problems Require a Plumber
Call a professional if you notice:
At this point, repair attempts often cost more than a proper fix or replacement.

Garbage Disposal Repair vs. Replacement: What Makes Sense?
Sometimes fixing isn’t the smart move.
