Pro Tip: If your garbage disposal isn’t working, first check for a tripped reset button, power supply, or jammed blades. Press the red reset button underneath, ensure it’s plugged in, and use an Allen wrench to manually turn the flywheel if it’s stuck.
Quick Answer: If your garbage disposal isn’t turning on, it may be an electrical issue or a jammed impeller. Reset the unit using the red button underneath, and if jammed, use an Allen wrench to turn the motor manually.
Before you panic or fork out cash for a new one, let’s dive deep into why your garbage disposal might be acting up—and how to fix it like a pro.
A well-functioning garbage disposal is the unsung hero of a clean kitchen. But when your garbage disposal is not working, chaos can quickly ensue. Leftover food scraps pile up, unpleasant odors linger, and you’re left frustrated, not knowing whether to fix it or call a plumber.
Common Causes for Garbage Disposal Not Working
When your garbage disposal stops working, several culprits could be behind the issue. From electrical problems to physical jams, pinpointing the root cause is the first step to restoring normalcy in your kitchen.
Power Issues and Electrical Failures
Believe it or not, sometimes the problem is as simple as a lack of power. A tripped circuit breaker or unplugged disposal can mimic more severe issues.
- Check the outlet: Ensure the unit is securely plugged in.
- Reset the unit: Press the red reset button underneath the unit.
- Check your circuit breaker: If tripped, flip it off and then back on.
Jammed Impellers or Grinding Chamber
The most frequent mechanical issue is a jam in the grinding chamber. Hard food items, bones, or even silverware can block the impellers.
- Turn off the power: Always unplug the unit before working on it.
- Use an Allen wrench: Insert it into the bottom slot and rotate to loosen the jam.
- Manual clearing: Use tongs or pliers to remove the obstructing object.
Clogged Drain Lines
If water is backing up, the clog might not be in the disposal but in the pipes.
- Run hot water and dish soap: This can loosen grease or gunk.
- Try a plunger: Gentle plunging can dislodge minor clogs.
- Snake the drain: Use a plumber’s snake if you suspect deeper clogs.
Signs That Your Garbage Disposal Is in Trouble
Before we jump into the fixes, it’s essential to recognize the symptoms of a malfunctioning garbage disposal. Identifying the problem accurately can save you time and money. Identifying warning signs early can save you from bigger headaches down the line.
Humming Noise but Not Spinning
This is a classic sign of a jam. The motor is getting power, but something’s preventing the blades from turning. Continuing to run it in this state can burn out the motor.
Slow Draining Sink
If water takes ages to drain, there may be a clog in the disposal unit or the pipes leading out from it. Sometimes it’s caused by improper disposal of fibrous foods or grease buildup.
Leaking Water
Leaks can develop from seals or cracks in the unit. This could mean loose mounting flanges, damaged gaskets, or even a failing internal unit.
Unusual Noises
Loud rattling or metal-on-metal sounds suggest something is stuck inside. Persistent humming without grinding usually means the motor is jammed.
Bad Odors
Rotting food particles can get stuck and produce a foul smell. Regular cleaning and flushing with citrus peels and baking soda can help.
No Sound or Power at All
If you flick the switch and your garbage disposal doesn’t respond—not even a hum—this likely points to an electrical issue. It could be something as simple as a tripped breaker or a loose connection.
DIY Troubleshooting Steps When Garbage Disposal Not Working
Before calling a plumber, go through these effective DIY steps:
Reset and Power Check
As basic as it seems, pressing the reset button or checking the plug solves over 50% of disposal issues.
Manual Rotation
Use an Allen wrench or special disposal wrench to manually rotate the blades and break free from jams.
Clean and Flush
Flush with hot water, vinegar, and baking soda to eliminate clogs and odors.
Check the Flywheel
If you hear a humming noise, the flywheel might be stuck. A gentle nudge using the disposal wrench can often free it up.
Garbage Disposal Maintenance Checklist

When You Should Replace Your Garbage Disposal
Not every issue warrants a repair. Sometimes, replacement is the smarter long-term choice.
Frequent Breakdowns
If your disposal requires constant fixing or resets, it might be nearing the end of its lifespan.
Old Unit (Over 10 Years)
Most disposals last around a decade. If yours is older, efficiency and reliability decline, and replacement becomes more cost-effective.
Visible Cracks or Rust
Signs of physical deterioration indicate that repairs might only be temporary fixes.
Preventive Maintenance for a Healthy Disposal
You can extend your disposal’s lifespan with just a few simple habits.
What to Avoid Putting Down the Disposal
- Fibrous foods (celery, corn husks)
- Starchy items (potato peels, rice)
- Bones and shells
- Coffee grounds
- Fats, oils, and grease
Best Practices for Daily Use
- Run cold water before and after use.
- Cut large scraps into smaller pieces.
- Clean monthly using ice cubes and rock salt.
Use Natural Cleaners
Avoid harsh chemicals. A mix of baking soda and vinegar cleans and deodorizes without harming the unit.
Garbage Disposal Not Working During Holidays? Here’s What to Do
Holidays bring heavy kitchen use. If your disposal fails during these times, quick action is crucial.
Immediate Fixes
- Check power and reset.
- Manually turn the flywheel.
- Avoid using the sink until it’s unclogged.
Temporary Workarounds
Have a drain cover and garbage bag handy to manage food waste until repairs are made.
When to Call Plumbing Point Inc.
DIY solutions are great, but some issues require expert attention.
Electrical Malfunctions
Never attempt to fix wiring unless you’re qualified. Leave this to the pros.
Persistent Leaks
If you’ve tightened all connections and leaks persist, the disposal might need to be resealed or replaced.
Internal Damage
If something internal like the motor fails, replacement is likely the best option.
If your garbage disposal not working is causing headaches, don’t panic. Begin with simple fixes like pressing the reset button, checking power sources, or manually unjamming the blades. If those steps don’t work, further inspection may be needed—but often, you can get your disposal back in action with little effort.
