ToggleSafety First: Precautions Before Troubleshooting
Most garbage disposals can pose serious risks if not handled appropriately. First things first, you want to make sure the unit is completely powered off before troubleshooting. That means either unplugging it or shutting off the circuit breaker.
And remember, never place your hands inside the device – the sharp blades can cause severe injuries.
Last but not least, always refer to the unit’s manual for specific safety guidelines before attempting any maintenance. After all, each model is unique and may require specific safety measures.
Common Garbage Disposal Issues
Symptoms that indicate a malfunctioning disposal unit include a humming sound (as opposed to a grinding noise), water leaks, slow draining, and failure to turn on.
Fixing Power Issues
If your disposal isn’t turning on, it’s likely a problem with the power supply.
Step 1: Check the Power

Start by checking if the disposal unit is properly connected to the power outlet – it’s a simple step, one that’s often overlooked.
Step 2: Check the Breaker

If the power cord is plugged in, but the unit is still not working, check the built-in circuit breaker. The unit may not turn on if it’s been tripped.
For instance, using the garbage disposal at the same time as other high-power appliances like a toaster can cause a tripped circuit breaker.
Step 3: Press the Reset Button

If the garbage disposal still isn’t turning on, press the reset button on the bottom of the unit. If the button keeps popping out, the unit may need to be replaced.
Supply:
- None
On average, you’ll need to replace your garbage disposal every 10 to 15 years.
Fixing a Clogged or Jammed Garbage Disposal
Clogs usually happen when food waste or other debris gets trapped in the garbage disposal. Fortunately, there’s a relatively easy fix.
Supplies:
- Hex wrench
- Flashlight
Step 1:
Using a flashlight, check to see if you can see the clog in the disposal.

Step 2:
If you can see the clog, use a hex wrench or a pair of pliers to manually turn the flywheel. That will free the disposal from whatever is causing the blockage.

Step 3:
After you’ve cleared the jam, run cold water and turn the disposal on and off in quick bursts. That will help clear any remaining debris and ensure your disposal is ready to be used again.

Never reach in with your hands to fix a clogged garbage disposal. Remember, safety first.
Fixing a Leaking Disposal
Common areas where leaks may occur include the sink flange, dishwasher hose, and discharge drainpipe.
Supplies:
- Screwdriver
- Plumber’s putty
- Clamps or bolts (optional)
- New gasket (optional)

Step 1:
If the leak is at the sink flange, it may be due to deteriorating sealant or loose bolts. To fix this, you’ll need to replace the seal and ensure the mounting apparatus is tightly secured.

Step 2:
If the leak is at the hose connecting the dishwasher to the disposal, you can fix the issue by tightening or replacing the relevant connections, including clamps or bolts.

Step 3:
If the discharge drainpipe is leaking, replacing the old gasket and ensuring the bolts are tight should do the trick.
Consider getting a new garbage disposal if water is leaking from the bottom of the unit.
Resetting Your Garbage Disposal
From time to time, you may need to reset your garbage disposal. For example, you may need to reset the unit if the internal circuit breaker has tripped. Here’s how to do it
Supplies:
- None
Step 1:
Locate the reset button, which is usually found on the underside or side of the under-sink.

Step 2:
Firmly press the reset button at the bottom.
If the button immediately pops back out after you press it, wait 10 minutes for the unit to cool down before trying again – that will allow the motor to reset.

Prolonging Your Garbage Disposal’s Lifespan

There are several things you can do to extend your garbage disposal’s lifespan.
For starters, you want to make sure you’re using it correctly. This means running cold water while the garbage disposal is running and for 10 to 20 seconds afterward – that will help flush down any remaining particles and prevent clogs.
And remember, never use hot water – it can cause fats and grease to liquefy and stick to the internal components, leading to buildup. Also, never put hard or fibrous items like popcorn kernels and celery down the disposal as these can cause jams and impact the blades.
Cleaning Your Garbage Disposal Unit
It’s also a good idea to clean your garbage disposal once every two weeks. That will help prevent odors from developing.
For the best results, we recommend using ACTIVE Garbage Disposal Cleaner.
Supplies:
- ACTIVE Garbage Disposal Cleaner

Step 1:
Run the faucet for one minute with hot water.

Step 2:
Reduce the water to a slow trickle, turn the faucet away from the drain, and place one ACTIVE Garbage Disposal Cleaner tablet inside the drain.

Step 3:
Run the garbage disposal and water until all of the foam drains, then turn off the unit.

When to Seek Professional Help
If troubleshooting fails or there’s leakage from the reset button, it may be time to seek professional help.
Other red flags include a reset button that does not stay depressed and smoke from the unit.
In some cases, you may need to replace the garbage disposal entirely. For example, this may be necessary if there are unfixable leaks, blown motors, or factory defects that cannot be repaired.
Depending on the type of unit that you choose, the cost of replacing a garbage disposal can range anywhere from $75 to $950.
DIY Fixes for Specific Garbage Disposal Problems
