Why is My Garbage Disposal So Noisy?
Why is My Garbage Disposal So Noisy?
July 26, 2019
The garbage disposal under your sink is a very convenient part of your kitchen. At the flick of a switch, the disposal will grind and pulverize any organic detritus that gets in it while you wash the dishes. It then drains the gunk away and is ready to go in just a matter of seconds. It’s a wonderful invention which is why it’s a little frustrating if it suddenly begins to hum, sputter or malfunction. Often, your disposal will make a noise when something isn’t right. To help you figure it out, the team at Mattioni is here to answer the question that has been in your mind: Why is my garbage disposal so noisy?
Humming or Whirring
- Jammed Impellers
If you hear your disposal making a distinct humming or whirring sound, it is most likely that an object has been jammed between the disposal’s shredder ring and the impellers. The hum is an indication that the motor of the disposal is still being powered, but the impellers are not moving. The shredder ring and the impellers work together to pulverize any gunk that has gotten in the disposal and are a vital part of your garbage disposal.
To fix the humming sounds, remember to turn off and unplug your disposal. You will find its plug underneath your sink. Wait a couple minutes for the impellers to stop moving and use a flashlight to find the object that is stuck. If you see the object, whether it’s a spoon, fork or any kind of bone, reach in with a gloved hand and carefully pull it out.
- Malfunctioning Flywheel
After you take out any objects, plug in the disposal. If the noise stops, you have solved the problem! If not, the flywheel of the disposal may not be working. The flywheel is a flat, disk-like mechanism that the disposal rotates to spin the impellers that help in shredding the food. You might have to take a more manual approach to fix this problem.
Check the bottom of your disposal for a 6-sided hexagon shaped hole. Insert the hex wrench that comes with the disposal into the hole. Use the wrench to turn the flywheel counterclockwise and clockwise until you feel the obstruction come free.
Rattling or Loud Grinding
If your disposal is making a rattling sound, a foreign object is most likely being clanged around by the impellers. Just like we mentioned before, turn off and unplug your garbage disposal and use a flashlight to find the object. Since the object is probably loose, it will be easier to pull it out using your hands or some tongs.
However, if you can’t find any object, there is a chance the impellers of your garbage disposal have become loose. Sometimes, the steel bolts that hold the impellers can slacken. You can try to fix this problem yourself by tightening the two bolts holding the impellers in place on the top of the disposal using a nut driver.
A squealing sound coming from your disposal is indicative of a larger problem. The moment you hear your disposal squealing it is best to turn it off and unplug it immediately. A squealing sound might mean the motor of the disposal is failing. The best solution to this would be to start looking into purchasing a new garbage disposal. You can also have a plumber you trust come look at your disposal and point out the severity of the problem.
Treat Your Disposal Well!
Remember to keep your garbage disposal in good condition! Be sure to avoid putting certain items down the disposal such as coffee grounds, eggshells and larger pieces of bone. These items can dull the impellers and can also make it harder for your drain to wash them out. In addition, frequently clean the sludge that tends to collect in the disposal using natural ingredients such as baking soda and vinegar. By maintaining your disposal regularly, you will be able to avoid costly repairs in the future.
