If you recently purchased your first home, it is only a matter of time before you run into a common kitchen problem: a garbage disposal that stops working, hums loudly, or refuses to drain. Many new homeowners throughout Highland, Edwardsville, Glen Carbon, Troy, and surrounding Metro East communities are surprised to learn how often garbage disposal repair is needed and how many issues can be prevented with simple steps.
Understanding how your disposal works and what to do when it fails can save you from unnecessary stress, expensive replacements, and kitchen backups. This guide walks you through the most common problems, DIY troubleshooting steps, and when to call Litteken Plumbing for professional help.
How Your Garbage Disposal Works
A garbage disposal grinds food waste into tiny particles so it can travel safely through your plumbing. Instead of sharp blades, it uses spinning metal impellers and a grinding chamber. When everything is working correctly, this process is fast and efficient. When something goes wrong, the unit can jam, overheat, or stop draining.
Because of how frequently disposals are used in homes across the Metro East, garbage disposal repair is one of the most common service requests we receive.
Common Garbage Disposal Problems
Understanding what can go wrong helps you catch problems early and avoid bigger issues down the road.
1. The Disposal Will Not Turn On
If you flip the switch and nothing happens, the problem may be electrical.
Possible causes:
• Tripped circuit breaker
• Loose wiring
• Overheating that triggered the reset button
• Failed switch or motor
Many first time homeowners are surprised by how often a simple reset solves the issue.
2. The Disposal Hums but Does Not Spin
A humming sound usually means the motor is receiving power, but the grinding chamber is jammed.
Common reasons:
• Foreign objects like utensils
• Hard food scraps
• Built up debris
• Worn internal components
This is one of the most frequent garbage disposal repair situations in older homes throughout Highland and Glen Carbon.
3. The Sink Drains Slowly
A slow drain does not always mean your disposal is broken. Food particles, grease buildup, or clogged pipes downstream can restrict water flow.
Signs include:
• Gurgling noises
• Standing water
• Foul smells
Homes with older plumbing in communities like O’Fallon or Edwardsville often experience this issue.
4. Leaking Disposal
Leaks can happen from:
• The top mounting ring
• Side connections to the dishwasher
• Cracks in the disposal housing
A cracked housing usually requires a full replacement.
5. Bad Odors
Food waste can collect in hidden areas inside the grinding chamber. This is a common complaint among homeowners who are new to maintaining a disposal system.
DIY Garbage Disposal Repair: What You Can Safely Try
Before calling a plumber, there are several safe troubleshooting steps homeowners can try. Always unplug or disconnect power first.
1. Press the Reset Button
Most disposals have a small red reset button on the bottom. If the unit overheats, it will shut off automatically.
Press it once and test the switch again.
2. Check the Circuit Breaker
If the disposal does not respond at all, check your electrical panel. A tripped breaker is an easy fix.
3. Clear a Jam Manually
If the disposal hums, you may be dealing with a jam.
• Turn off the power
• Use an Allen wrench in the bottom hex hole to rotate the grinding plate manually
• Remove debris with tongs (never your hand)
Avoid forcing it, especially if you live in a home with older piping in the Metro East.
4. Freshen the Disposal
To fix mild odors:
• Grind ice cubes
• Add a small amount of baking soda and vinegar
• Flush with cold water
Avoid chemical drain cleaners, which can damage plumbing and disposals.
5. Check for Leaks
Place a cloth under the disposal and run water to locate the source.
• Loose mounting rings can often be tightened
• Loose hose connections can be resealed
Cracks in the disposal body, however, require replacement.
When DIY Fixes Are Not Enough
Not every garbage disposal repair is safe for homeowners to attempt. Call a professional if you notice:
• Burning smell coming from the unit
• Water leaking from internal seams
• Electrical problems
• Repeated jamming
• Grinding noises even with no debris
• A rusty or cracked disposal unit
• Persistent slow drains
Homes in Highland, Edwardsville, and O’Fallon often have mixed-age plumbing systems, which means a disposal issue may actually be a deeper plumbing problem.
How to Prevent Future Disposal Problems
Taking care of your disposal can dramatically reduce the need for repairs.
What to Put In
- Soft foods
• Small scraps
• Ice cubes
• Cold water while running the disposal
What to Never Put In
- Grease or oil
• Pasta, rice, or starchy foods
• Coffee grounds
• Eggshells
• Fruit pits
• Bones
• Vegetable peels that tangle
These items commonly cause clogs in homes throughout Glen Carbon and Troy.
How Long Does a Garbage Disposal Last?
Most disposals last 8 to 12 years. Hard water, lack of maintenance, and frequent heavy use can shorten their lifespan. If your disposal is old or requires multiple repairs, replacing it may be more cost-effective.
