The garbage disposal is a kitchen essential in many American homes, making cleanup quick and efficient. However, when it stops working, it can disrupt your entire routine. If your garbage disposal isn’t working the way it should, don’t worry: Most problems can be fixed with a little troubleshooting.
9 Reasons why your garbage disposal is not working and how you can fix them
1. No Power to the Device
If your garbage disposal doesn’t turn on or makes any sound, the problem may be caused by a lack of power.
How to Fix it
- Check the outlet: Look under the sink to make sure the disposal is securely plugged into the outlet. Sometimes the cord comes loose.
- Inspect the circuit breaker: If the outlet isn’t getting power, check your circuit breaker box. Reset the circuit breaker if it’s tripped.
- Press the reset button: Garbage disposals have a reset button (usually red) located on the bottom of the device. If the grinder is blocked, press it to restore power.
2. Blocked grinder blades
If your grinder is humming but not grinding, the blades may be blocked by something stuck inside.
How to fix it:
- Turn off the power: Always unplug the appliance or turn off the circuit breaker before inspecting it.
- Use a hex key: Most grinders come with a hex key or Allen key. Insert it into the hex socket on the bottom of the grinder and turn it back and forth to remove the blockage.
- Clear blockages: Look inside the grinder to see if there are any objects such as bones, utensils, or food residue that may be causing a blockage. Use tweezers or pliers to safely remove debris, never your hands.
3. Blocked drain line
If water doesn’t drain from your sink, the problem may be with the pipes rather than the disposal.
How to Fix it:
- Disconnect the drain hose: Open the drain hose under the sink and check for blockages.
- Clear the blockage: Use a plumber or auger to break up and remove the blockage.
- Water flush: Run cold water through the system to flush out any remaining debris.
4. Overheating or overloading
If the garbage disposal stops working during use, it may be overheating.
How to fix it:
- Wait for it to cool down: Allow the grinder to cool for about 10 to 15 minutes.
- Reset the device: Press the reset button on the bottom of the grinder when it cools down.
- Avoid overloading: Pour garbage into the disposal slowly and always run cold water during operation to avoid overheating.
5. Leaky grinder
Leaks around a garbage disposal may be a sign of loose connections or worn parts.
How to fix it:
- Inspect all connections: Check where the disposal meets the sink flange, drain pipe, and dishwasher hose for leaks.
- Tighten loose parts: Use a wrench to tighten loose screws or connections.
- Replace gaskets or gaskets: If the leak continues, a worn gasket or gaskets may need to be replaced.
6. Strange noises
Squeaks, rattles, or creaks are usually caused by something stuck in the grinder.
How to fix it:
- Turn off the device: Disconnect the power before investigating.
- Check for foreign objects: Glass, metal, or small hard objects can cause rattling noises. Carefully remove them using pliers.
- Inspect for damage: If the blades or other components appear damaged, they may need professional repair or replacement.
7. Odors
Unpleasant odors may persist from a garbage disposal if food particles are trapped or bacteria have accumulated.
How to fix it:
- Clean the disposal: Pour a mixture of baking soda and vinegar into the unit, let it sit for 10 minutes, then rinse with warm water.
- Grate citrus peels: Grating lemon or orange peels can naturally deodorize your grinder.
- Clean the rubber splash guard: Remove and scrub the rubber flange over the sink opening, as it can trap food and grease.
8. Worn-out equipment
If your garbage disposal breaks down often, it may be at the end of its life.
How to fix it:
- Check the age: Most grinders last between 8 and 15 years, depending on use and maintenance.
- Consider replacement: If repairs are frequent or expensive, replacing the device may be a better long-term solution.
9. Improper use
Sometimes disposal problems come from what you put in it. Putting wrong waste products can clog the garbage disposal frequently.
How to fix it:
- Avoid hard objects: Don’t grind bones, peels, or fibrous foods like celery and corn husks.
- Never add grease: Grease can harden in pipes and cause clogs.
- Run water during use: Always run cold water to help flush waste through the system.
Tips to avoid waste disposal problems
- Run your garbage disposal regularly to keep it from building up.
- Rinse with cold water before and after use to avoid clogs.
- Clean the unit every few weeks to prevent odors and buildup.
