Garbage disposals are incredibly convenient kitchen appliances that make cleanup easier by grinding up food waste. However, like any appliance, garbage disposals can run into problems from time to time. Whether it’s failing to turn on, clogging, or emitting foul odors, these issues can be frustrating and disruptive to your kitchen routine.
Understanding the common garbage disposal problems and how to fix them can save you time, money, and the hassle of calling a plumber. In this guide, we’ll walk through the most common issues homeowners face with their garbage disposals and offer simple, effective solutions to help keep your disposal running smoothly.
Garbage Disposal Won’t Turn On
One of the most common issues with garbage disposals is when the unit won’t turn on at all. If you flip the switch and nothing happens—not even a humming sound—it could indicate a power issue. This is one of the more straightforward common garbage disposal problems that can often be fixed with a few simple steps.
First, check if the unit is plugged in. It may sound obvious, but garbage disposals can sometimes become unplugged if the cord is bumped or loosened under the sink. If it’s plugged in, the next step is to check the circuit breaker. If the circuit has been tripped, reset it, and see if the garbage disposal starts working.
If the disposal is still not turning on, try pressing the reset button located on the bottom of the unit. The reset button is designed to trip if the disposal overheats or if there’s a minor electrical issue. After pressing the reset button, wait a minute and try turning on the disposal again.
If none of these steps work, it’s possible that there’s a more serious electrical issue. Testing the outlet with another appliance can help determine whether the problem is with the garbage disposal or the electrical wiring. In some cases, you may need to call an electrician to inspect the wiring.
These power-related issues are among the most common garbage disposal problems, and they are often easy to fix. Ensuring that the disposal has power and is correctly plugged in can quickly resolve the issue without the need for a professional.
Garbage Disposal Is Jammed
A jammed garbage disposal is another frequent problem homeowners encounter. You’ll know the disposal is jammed if you turn it on and hear a humming sound, but the blades aren’t spinning. In most cases, a piece of food or a foreign object is stuck inside the unit, preventing the blades from moving. This is one of the most frustrating common garbage disposal problems, but it can often be fixed without the help of a plumber.
First, turn off the garbage disposal to avoid any accidents. Never try to clear a jam while the disposal is on, as this can be dangerous. Once the power is off, check the bottom of the unit for a small hole where a hex key or Allen wrench can be inserted. Most disposals come with a hex wrench specifically for this purpose.
Insert the wrench into the hole and turn it back and forth. This manual movement should help dislodge whatever is stuck inside the unit. After turning the wrench, check inside the disposal for any visible blockages. Use tongs or pliers to carefully remove any food debris, bones, or other objects that may be causing the jam.
If the jam persists even after using the hex wrench, it’s possible that the motor is overheating or damaged. In this case, pressing the reset button on the bottom of the unit may help. If the disposal still won’t work, you may need to contact a professional for further inspection.
Jammed disposals are one of the most common garbage disposal problems, but with the right tools and a little patience, they’re usually easy to fix at home.
Slow Draining or Clogged Garbage Disposal
A slow-draining or clogged garbage disposal is another common issue that can disrupt your kitchen’s functionality. When food particles, grease, or other debris accumulate in the pipes, it can cause water to drain slowly or even result in a complete blockage. This is one of the more serious common garbage disposal problems but can often be resolved with some basic troubleshooting.
The first step in addressing a slow-draining disposal is to ensure you’re running cold water while using the unit. Cold water helps solidify grease and food particles, making them easier to grind up and flush through the pipes. If you’re already using cold water and the disposal is still slow to drain, the next step is to try cleaning the unit.
A simple way to clean your garbage disposal and pipes is by using a baking soda and vinegar solution. Pour about half a cup of baking soda into the disposal, followed by a cup of vinegar. Let the mixture fizz for about 10 minutes before flushing it with hot water. This combination helps break down food particles and grease that may be causing the blockage.
If this method doesn’t work, you can also try using a plunger to dislodge the clog. Place the plunger over the sink drain and create a seal. Pump the plunger up and down a few times, then check to see if the water drains properly. For more stubborn clogs, a plumber’s snake may be needed to clear the pipes.
Slow drainage is one of the common garbage disposal problems that should be addressed quickly to avoid larger plumbing issues. By keeping the disposal clean and using it properly, you can prevent these clogs from becoming a recurring issue.
Foul Odors from the Garbage Disposal
If your garbage disposal emits unpleasant odors, it’s likely due to food particles and debris trapped inside the unit. Over time, leftover food can rot and create bad smells, which can make your kitchen an unpleasant place to be. This is one of the most annoying common garbage disposal problems, but fortunately, it’s easy to fix with regular cleaning.
One of the simplest ways to get rid of bad odors is by using ice cubes and salt. Drop a handful of ice cubes and about a quarter-cup of coarse salt into the disposal, then run cold water and turn the disposal on. The ice helps clean the blades while the salt scrubs the inside of the disposal, removing stuck-on food particles.
For a more thorough cleaning, you can also use a mixture of baking soda and vinegar. Pour half a cup of baking soda down the disposal, followed by a cup of white vinegar. Let the mixture sit for 15 minutes, allowing it to break down food particles and neutralize odors. Afterward, flush the disposal with hot water to rinse everything away.
Another option is to use citrus peels. Grinding up lemon or orange peels in your disposal not only helps clean the unit but also leaves it smelling fresh. Citrus oils naturally deodorize the disposal and help break down any remaining food debris.
In some cases, foul odors can come from food trapped under the rubber splash guard. Lift the guard and use a brush to clean underneath, where food particles may have collected over time. Keeping this area clean will help prevent odors from returning.
Regular cleaning is essential for avoiding foul smells, making it one of the easiest common garbage disposal problems to manage.
Leaking Garbage Disposal
A leaking garbage disposal is a serious issue that can cause damage to your kitchen cabinets and flooring if not addressed promptly. This is one of the most concerning common garbage disposal problems, as leaks can come from several different areas of the unit, each requiring a specific fix.
The first step in addressing a leak is to identify where it’s coming from. Common leak points include the sink flange, the bottom of the unit, and the hose connections. If the leak is coming from the sink flange, it may be because the seal between the disposal and the sink has worn out or become loose. In this case, tightening the mounting screws or applying fresh plumber’s putty around the flange can often stop the leak.
If the leak is coming from the bottom of the disposal, it’s likely due to a crack or internal damage to the unit itself. Unfortunately, if the disposal is cracked, it will need to be replaced. Attempting to repair a cracked disposal is usually not worth the cost or effort.
Leaks around the hose connections are another common problem. Check the hoses that connect the disposal to your plumbing and tighten any loose connections. If the hoses are damaged or cracked, they will need to be replaced to stop the leak.
Detecting a leak early can save you from more significant water damage, so it’s important to regularly check under your sink for signs of moisture or pooling water. By addressing leaks promptly, you can avoid one of the more expensive common garbage disposal problems.
