Quick Fixes and When to Call a Pro
If you’ve ever gone to flip the switch on your garbage disposal only to hear a scary grinding sound—or worse, nothing at all—you know how frustrating a failing disposal can be. These little machines work hard behind the scenes to grind up food scraps and keep your kitchen drain moving freely. But like any appliance, they need the right care to keep functioning properly.
Today, we’re going to walk through the most common garbage disposal issues, some quick fixes you can try at home, and the moment when you should put the wrench down and call in a professional.
1. Your Garbage Disposal Won’t Turn On
You flip the switch… and silence. No humming, no grinding—just a dead unit.
Before you assume the disposal is fried, try these simple checks:
Check the Reset Button
Underneath your disposal is a small red reset button. If the unit overheats or jams, this button pops out. Press it back in firmly and try running the disposal again.
Check the Power Source
Make sure it’s plugged in (yes, it happens).
Then, check your kitchen’s GFCI outlet—these outlets often trip during surges or moisture exposure. Reset it if necessary.
Check the Breaker Panel
If neither the reset button nor the GFCI restores power, your breaker may have tripped. Reset it and test the disposal again.
If you’ve tried all of the above and still get no response, the motor may be burned out. At that point, it’s best to have a technician inspect the unit to determine whether it can be repaired or needs replacement.
You can explore how we diagnose deeper plumbing issues with professional sewer and drain inspection services if the problem turns out to be more than just the disposal.
2. The Garbage Disposal Hums But Doesn’t Spin
This is one of the most common symptoms of a jammed disposal. A low buzzing noise means the motor has power, but the blades can’t rotate.
Try Manually Freeing the Jam
-
Turn off the disposal.
-
Disconnect power (unplug it or cut off the breaker).
-
Look under the unit for a small hex-shaped opening.
-
Insert the included Allen wrench and turn it back and forth to break the jam.
Common culprits include:
-
Hard seeds
-
Small bones
-
Utensils
-
Fibrous foods
Once the blades rotate freely again, restore power and press the reset button before testing the unit.
If your disposal jams frequently, it may be a sign of buildup, dull blades, or a blockage deeper in the drain line. Our plumbers can check your drain system and recommend repairs if needed. You can learn more about how we handle these hidden issues through our sewer line troubleshooting services in Williamstown, NJ.
3. The Disposal Drains Slowly
If water sits in your sink instead of draining quickly, the problem may actually be in the drain line—not the disposal itself.
Try These Quick Fixes:
-
Run cold water for 30 seconds before and after using the disposal.
-
Avoid putting grease, pasta, coffee grounds, or large amounts of starchy foods down the drain.
-
Use a safe enzyme drain cleaner (avoid harsh chemical ones).
Often, a slow-draining disposal connects to buildup in the kitchen drain or a partial blockage in the main sewer line.
For homes with repeated slow-drain issues, our team can perform a video inspection to find the exact cause. See how we diagnose these blockages with advanced sewer camera inspections in Williamstown.
4. Strange Noises Coming from the Disposal
Hearing rattling, clanking, or grinding? Turn it off immediately. Something that shouldn’t be there is bouncing around inside the chamber.
Common foreign objects include:
-
Bottle caps
-
Silverware
-
Small pieces of glass
-
Fruit pits or stones
Carefully remove the object with tongs or pliers. Never reach into the disposal with your hand, even if the unit is powered off.
Persistent strange noises may signal broken blades or internal damage. In those cases, the disposal may need replacement.
5. Foul Odors That Won’t Go Away
A stinky disposal is usually a sign of trapped food particles inside the chamber or drain line.
Try cleaning it with:
-
Ice cubes and coarse salt
-
A few lemon slices
-
Baking soda and vinegar (followed by boiling water)
If smells return quickly, it might indicate a deeper clog or buildup inside the drainpipe. That’s where an inspection becomes valuable—because sometimes those odors are actually signaling a sewer line issue, not just leftover food.

6. When to Call a Professional
Garbage disposals are simple machines, but they can create big plumbing problems if not handled correctly.
You should call a plumber if:
-
The disposal repeatedly jams
-
You smell sewage near the sink
-
Water leaks from the bottom of the unit
-
The motor won’t turn on after resetting
-
Drains back up even when the disposal runs
A malfunctioning disposal can sometimes expose bigger issues—like drain line blockages, venting problems, or sewer line cracks. That’s why it pays to have an experienced plumber look over the system if you’re unsure.
At DrainPro Solutions, we diagnose disposal failures, repair or replace units as needed, and check your drain and sewer lines to make sure your whole system is working smoothly.

Manny was prompt, described the situation to me, and quoted me a price. His work ethic exceeded my expectations. The work was not as involved as he first thought so he adjusted the amount of the bill accordingly. He did a great job. He was a personable, no-nonsense business man which we appreciated. I would hire him again. Also, he is bi-lingual which helps.
