Garbage disposal is necessary, especially if you often cook a lot of meals for your family on a daily basis and you need to quickly get rid of every bit of waste in a very convenient way. But you need to remember that garbage disposal has its limits.

If you observe some of these things on your garbage disposal, immediately call your local plumber to fix it as soon as possible.

Hearing Unusual Noises 

These unusual noises that you observe in the garbage disposal might result in a serious matter. Turn off the power to your disposal prior to having a close look! Check anything down the drain immediately that may be blocking the unit; it might be a utensil or food waste that can’t be easily ground up.

If you find something down there, remove it and try to use the garbage disposal again. However, if you can’t find anything, it’s time to call for professional help, or you might want to replace your garbage disposal.

Foul Smell

If the garbage disposal has been installed for a very long time, you might want to replace it already or seek help from your local plumber because what causes the foul smell might be particles of old food and waste that were stuck in the unit.

Occasionally using a freshener in the disposal could eliminate foul smells before they are out of hand.

Frequent Need to Reset

If you find yourself frequently pressing the reset button, it might indicate a serious problem with your garbage disposal. Resetting it means you need professional help because it might malfunction anytime soon. The reset button should only be pressed a few times, infrequently, so you need to observe how many times you press it.

Leaking Water

Like what was mentioned, garbage disposal has its limits. It might have developed cracks or even sprang a leak. When leaking from your garbage disposal happens, inspect all pipes and drain lines, but if it can’t be easily repaired, you might want to consider replacing it with a new one.

Does Not Turn On

If your garbage disposal won’t turn on, immediately check the connected circuit if it has blown. If it won’t work at all, you'll need to call for professional help. Make an appointment for a garbage disposal inspection if the electrical system seems to be functioning properly because it might be a sign of a failing motor, or it might have blown out entirely.

Clogged

When using a garbage disposal, only put small amounts of food waste and other objects down the drain to prevent it from clogging. Observe how it functions, and if you notice that even if you only put small amounts of food waste in it and it still clogs, it's a sign of malfunctioning your device.

These clogs could also indicate that you need a garbage disposal with a higher capacity model.

Avoid Clogs

It is true that garbage disposals are made to grind waste, but you should always keep in mind the objects that you need to avoid putting down the drain. Here are some of the things to avoid putting down your drain:

  • large bones of animals,
  • coffee grounds,
  • grease,
  • oil,
  • onions,
  • celery,
  • eggshells,
  • rice,
  • potatoes,
  • pasta,
  • and seafood shells.

Reduce Waste Produced

Garbage disposals need a helping hand too. When you have large amounts of food waste that need to be put down in your garbage disposal, break them into small amounts so they can be ground up smoothly down the drain.

Run Cold Water While Disposing

Cold water is a big help in avoiding clogging your garbage disposal. You can also prevent grease or oil that you put down the drain from solidifying.

Properly Clean

Always pour plenty of drops of dishwashing liquid down the drain with cold water after using it. This will help you prevent an awful smell and help keep your garbage disposal clean.

When your garbage disposal begins to smell, try to grind citrusy fruits to freshen the smell of your unit naturally. Ice cubes can also help you maintain your unit. Grinding ice cubes once a month can sharpen the blades of the unit and remove waste that is stuck on your disposal’s walls.

No, although drain cleaners help you by breaking apart any food waste and other objects that are clogged in the drain, drain cleaners aren’t safe to use for your garbage disposal. Drain cleaners have strong chemicals in them that can eventually break the pipes down there if used frequently.

How do you reset a garbage disposal?

Pressing the reset button on your garbage disposal a few times isn’t a bad thing. Sometimes, clogging and overloading the garbage disposal is normal. The garbage disposal turns off automatically when it gets clogged, overheats, or when there’s something wrong with the motor. The only solution to fix it is to simply reset it so that it will work properly again.

Make sure the garbage disposal is turned off at all times. Press the reset button, and if it does not stay in, wait for ten minutes and try again.

To test if the disposal is operating, locate the red button below, press it back in, and run it again. You should also inspect the electrical panel to see if the breaker needs to be flipped back on. Your garbage may need to be fixed or replaced if it doesn’t work and you have been frequently pressing the reset button.
