Why Your Garbage Disposal Doesn't Work

Garbage disposals are a staple in modern kitchens, making the disposal of food waste more convenient. However, when they stop working, it can be frustrating and confusing. Here's a comprehensive look at why your garbage disposal might not be functioning and what you can do about it.

1. Overloaded with Waste

The most common reason for a garbage disposal malfunction is simply overloading it with too much waste at once. Disposals are designed for small batches of food waste:

• Solution: Feed your disposal in small amounts, allowing the motor to catch up. Always run cold water while the disposal is operating to help flush out the waste.

2. Jam or Clog

If your disposal hums but doesn’t grind, it’s likely jammed or clogged:

• Jam: Hard items like bones, fruit pits, or utensils can jam the blades.

  • Solution: Use the disposal's reset button if available. If that doesn't work, you might need to manually turn the impeller with an Allen wrench through the bottom of the disposal to dislodge the item.

• Clog: Fibrous or starchy foods like potato peels, celery, or coffee grounds can form a thick paste that clogs the disposal.

  • Solution: Avoid putting these materials in the disposal. If already clogged, you might need to fish out the debris with pliers or use a plunger to clear the drain line.

3. Blunt or Damaged Impellers

Over time, the impellers can become blunt or even break:

• Solution: Unfortunately, this usually means replacement is necessary, either of the impellers or the entire disposal unit if it's older or not worth repairing.

4. Electrical Issues

If there's no sound or movement when you switch on the disposal, consider electrical problems:

• Tripped Circuit: Check if the disposal's circuit breaker has tripped.

  • Solution: Reset the breaker. If it trips repeatedly, there might be a short circuit or the disposal could be overheating.

• Faulty Switch: The wall switch or the disposal's own switch might be faulty.

  • Solution: Test with a multimeter or consider hiring an electrician to diagnose.

5. Motor Burnout

Continuous use without giving the motor time to cool down or disposing of items the unit wasn’t meant to handle can lead to motor failure:

• Solution: Replacement of the motor or, more commonly, the entire disposal unit is often the only fix here.

6. Leaks

Leaks can occur from the drain flange or from the disposal unit itself:

• Solution: Check connections for loose fittings or worn out gaskets. Tighten or replace parts as needed, but if it's the disposal unit leaking, you might need a new one.

7. Corrosion

Especially in older units, corrosion can lead to failure, particularly if the disposal has been exposed to harsh chemicals or too much acidic waste:

• Solution: Regular cleaning with vinegar or baking soda can help, but severe corrosion often means replacement is necessary.

Preventive Maintenance

To keep your garbage disposal running smoothly:

• Run Cold Water: Always during and after use to help with grinding and flushing.

• Use Ice: Grind some ice cubes occasionally to sharpen blades and clean the unit.

• Avoid Harsh Chemicals: Use natural cleaners to avoid damaging the unit.

• Regular Cleaning: Lemon or orange peels can help deodorize and clean the disposal.
