Prevention And Maintenance Tips
Run Cold Water: Always run cold water while using the garbage disposal to help flush waste down the drain.
Avoid Fibrous Foods: Keep fibrous foods like celery, corn husks, and onion skins out of the disposal, as they can cause jams.
No Grease or Oil: Never pour grease or oil down the disposal as it can solidify and cause clogs.
Dispose of Bones Properly: Do not put bones in the garbage disposal, as they can break the blades or cause jams.
Clean Regularly: Clean your garbage disposal regularly by grinding ice cubes and lemon peels to keep it fresh and free of debris.
If you’ve tried the DIY methods and your garbage disposal is still humming, it might be time to call a professional plumber. They can diagnose and fix garbage disposal issues, such as a damaged motor, that may be causing the problem.
Garbage Disposal FAQs
1. What causes a garbage disposal to hum but not grind?
A humming garbage disposal usually indicates a jam or a stuck impeller. The motor is still running, but the grinding mechanism is unable to move due to a foreign object or built-up food debris. The humming sound is a result of the motor trying to turn the impeller but being unable to do so.
2. Is it safe to use a garbage disposal that’s humming?
No, it is not safe to use a humming garbage disposal. The humming indicates that the disposal is jammed, and continued use may lead to motor burnout, which can cause irreversible damage. Turn off the power to the disposal immediately and address the issue before attempting to use it again.
3. How can I fix a garbage disposal that’s humming but not working?
To fix a humming garbage disposal, follow these steps:
- Turn off the power and unplug the disposal.
- Inspect the grinding chamber for visible obstructions.
- Use a plunger or Allen wrench to free the impeller.
- Press the reset button on the bottom of the unit.
- Test the disposal to ensure it’s working properly.
If these steps don’t resolve the problem, consult a professional plumber.
4. Can a humming garbage disposal be a sign of a bigger problem?
While a humming garbage disposal is often a sign of a jam or stuck impeller, it may also indicate a more serious issue, such as a failing motor or damaged internal components. If you have tried the steps mentioned above and the disposal is still humming, it’s best to call a professional plumber to diagnose and fix the issue.
5. How can I prevent my garbage disposal from humming in the future?
To prevent your garbage disposal from humming, follow these tips:
- Run cold water before, during, and after using the disposal.
- Avoid putting fibrous or hard materials into the disposal.
- Cut large food items into smaller pieces before disposing of them.
- Regularly clean your garbage disposal with a mixture of baking soda and vinegar.
- Perform periodic maintenance checks to ensure the disposal is functioning correctly.

robert grover,
When your dishwasher runs and drains, it goes through the bottom of the garbage disposal, check to see if there is a blockage in the bottom of the garbage disposal.
Be sure the “knock out hole” is fully removed from the disposal and nothing is jammed up in the disposal.

My Badger 5 Garbage Disposal has started stopping to run after our dishwasher runs.
I am able to fix the jam with the wrench but it happens again after running the dishwasher.
It continues to work ok until we start the dishwasher again. Any Ideas?
Thanks!!! It was humming but not turning and following your advice turned it with an Allen wrench and it took care of it. Appreciate it!
So a spoon fell in the disposal and I couldn’t pull it out. Watched a video of a guy saying to use the wrench on the bottom, so I turned it back and forth and my mom tried to pull it out. She still couldn’t get it and when we went to trade, I couldn’t feel the spoon at all. We turned it on to see if it was still rattling and it did for a second before it stopped and sounded normal again. Did the spoon drop through? Is this okay to leave or should we figure out how to take it apart to remove it still?
Thank you so much for the video help!!! We fixed it with the allen wrench trick and did not have to go to Lowes to buy a new one!!! Happy Father’s day to us!
OH MY GOD! You saved the day! All I had to do was put the alan wrench in and unjam the machine. Best day ever!
I thought I was going to have take the damn thing apart myself or worse yet call somebody!
My problem is that the motor runs and then it stops after 2-3 seconds and starts humming.
This happened even after I had cleared out all solids in the disposal and clear water is passing through.
My disposal is just over a year old.
The thing that finally worked for me was the very hot water and liquid soap. After no success doing all the standard stuff (reset, hex, which was totally free), I got all of the water out of the sink down to the blades and then poured liquid dish detergent in, followed by lots of boiling water. Took a while, but after churning and letting it stand and adding another pitcher of hot boiling water, it finally took off.
Do NOT put parsnip skins and tops down the disposal!
Thanks to the gal who told us about the dawn and hot water (any liquid dish soap will do).
So helpful! Got out the tool kit and used my Allen wrench to unstick the fly wheel. Thank you! (PS feeling pretty proud!! No husband required!)
thank you sooooo much. the allen wrench worked. i thought i would have to get a new disposal. neat little trick with the wrench. now i also know why that is with the disposal. i’m soo glad you were here to help.
