Why Your Garbage Disposal Suddenly Stops Working

In this comprehensive article, we’ll explore the various reasons why your garbage disposal may suddenly stop working and offer tips on how to troubleshoot and prevent future issues.

A garbage disposal is an essential component of any modern kitchen, making food waste disposal a breeze. However, have you ever experienced the frustration of your garbage disposal suddenly stopping in the middle of a task? This can be inconvenient, especially if you have a lot of waste to dispose of.

In this comprehensive article, we’ll explore the various reasons why your garbage disposal may suddenly stop working and offer tips on how to troubleshoot and prevent future issues.

How does a garbage disposal actually work?

Well, it’s made up of several parts, including the motor, shredder, and impeller. When you turn on the disposal, the motor starts spinning the shredder plate at high speeds, which in turn grinds up the food waste.

The impeller then helps to push the ground-up waste through the drain pipes with the help of water.

It’s important to note that electricity plays a crucial role in the functioning of a garbage disposal. Without a proper electrical connection, your disposal simply won’t work. So, if you’re experiencing issues with your disposal, it’s worth checking the electrical connection first.

Signs Your Garbage Disposal Is Failing

Even with proper maintenance, garbage disposals can sometimes fail unexpectedly. Here are some signs that your garbage disposal may be failing:

Unusual sounds

If you hear grinding, rattling, or other strange sounds when you turn on your disposal, it could indicate a problem with the motor or blades.

Slow drainage

If water is draining slowly from your sink, it could be a sign that your disposal isn’t grinding up the food waste properly.

Foul smells

A persistent foul odor coming from your sink can indicate that food waste is stuck in your disposal or drain pipes.


If you notice water leaking from your disposal or the area around it, it could be a sign of a damaged or worn-out seal.

Electrical issues

If your disposal won’t turn on at all, or if it turns on but doesn’t grind up the food waste, it could be an electrical issue such as a faulty switch, wiring, or motor.

If you experience any of these issues, it’s important to address them as soon as possible to prevent further damage to your disposal or drain pipes.

 Garbage disposal has stopped working Рwhat could be the cause?

Here are some of the most common reasons why a garbage disposal might suddenly stop working:

Food blockage

If you’ve been putting large chunks of food or hard materials like bones down your disposal, it could cause a blockage that prevents the blades from spinning.

Worn-out blades

Over time, the blades in your disposal can become dull or damaged, which can lead to grinding problems.

Faulty motor

If the motor in your disposal is faulty or burned out, it won’t be able to spin the blades to grind up the food waste.


Garbage disposals are designed to handle certain amounts of food waste at a time. If you’ve been overloading your disposal with too much food waste, it could cause the motor to overheat and stop working.

Power issues

If your disposal isn’t receiving power, it won’t be able to function properly. This could be caused by a tripped circuit breaker, a blown fuse, or a problem with the electrical connection.

Troubleshooting Your Garbage Disposal

If your garbage disposal has suddenly stopped working, don’t panic! Here are some troubleshooting tips to help you get it up and running again:

How to reset your garbage disposal

Many garbage disposals have a reset button that you can press to reset the unit. Look for a small red or black button on the bottom of the unit and press it firmly to reset the disposal.

Using a plunger to clear a clog

If your disposal is clogged, try using a plunger to clear the blockage. Fill the sink with enough water to cover the top of the plunger, place the plunger over the drain, and push and pull the plunger vigorously to create suction and force the blockage through the drain.

Removing foreign objects in the disposal

If there’s something stuck in your disposal, like a piece of silverware or a small toy, use a pair of tongs or pliers to carefully remove the object. NEVER put your hand down into the disposal to try to remove an object, as this can be extremely dangerous.

Checking the electrical system

If you’ve tried resetting the disposal and clearing any blockages, the problem may be with the electrical system. Check the circuit breaker or fuse that powers the disposal to make sure it hasn’t tripped or blown. You can also check the wiring connections to make sure they’re secure.

Preventing Garbage Disposal Issues

Prevention is key when it comes to avoiding garbage disposal issues. Here are some tips to keep your garbage disposal functioning properly:

Avoid putting non-food items in the garbage disposal

Garbage disposals are designed to grind up food waste, not non-food items. Avoid putting anything other than food waste in the disposal.

Cut food waste into small pieces

Large pieces of food waste can lead to clogs in the disposal. Cut food waste into small pieces before putting it in the disposal.

Run cold water when using the garbage disposal

Cold water helps solidify grease and oil, making it easier to grind up and prevent clogs.

Regular maintenance and cleaning

Regular cleaning and maintenance can help keep your garbage disposal functioning properly. Use a mixture of baking soda and vinegar to clean your disposal, and consider using a disposal cleaner regularly

By following these simple troubleshooting steps, you may be able to save yourself the cost of a service call and get your garbage disposal back to full function.


How long do garbage disposals last?

Garbage disposals can last for up to 12 years, depending on how well they are maintained and how frequently they are used. Regular maintenance and cleaning can extend the lifespan of a garbage disposal.

Can I put coffee grounds in my garbage disposal?

It is not recommended to put coffee grounds in a garbage disposal, as they can accumulate and cause blockages. Coffee grounds can also create a sludgy paste that can clog the drain and damage the disposal blades.

How can I tell if my garbage disposal needs to be repaired or replaced?

Some signs that your garbage disposal may need to be repaired or replaced include unusual sounds, slow drainage, foul smells, leaks, and electrical issues. If you notice any of these signs, it is best to call a professional for an assessment.

Can I install a garbage disposal myself?

It is possible to install a garbage disposal yourself if you have the necessary skills and tools. However, it is recommended to hire a professional for the installation, as mistakes can lead to damage to the disposal or even injury.

How do I maintain my garbage disposal?

To maintain your garbage disposal, it is important to avoid putting non-food items in it, cut food waste into small pieces, run cold water when using the disposal, and perform regular maintenance and cleaning.

You can clean the disposal with DIY solutions or hire a professional cleaning service. It is also recommended to have your disposal inspected annually by a professional.
