Garbage Disposal Repair: Troubleshooting Common Problems

A properly functioning garbage disposal makes kitchen cleanup easy, but when it starts acting up, it can cause frustrating clogs, foul odors, and even plumbing backups. Many garbage disposal problems can be fixed with simple troubleshooting, but in some cases, professional repair or replacement is necessary.

If your garbage disposal is jammed, leaking, or not working at all, here’s what you need to know about diagnosing and fixing common issues. Contact 1st Choice Plumbing, Flood & Restoration at 866-437-0205 for help from a local plumber.

How Does a Garbage Disposal Work?

Before diving into repairs, it helps to understand how a garbage disposal operates. Inside the unit, a set of spinning impellers and grinding plates break food scraps into small particles. These particles are then flushed away through the drain. When a problem arises, it’s usually due to mechanical failure, improper use, or buildup within the system.

Common Garbage Disposal Problems and How to Fix Them

1. Garbage Disposal Won’t Turn On

If your disposal isn’t making any noise when you flip the switch, it’s likely an electrical issue.

Troubleshooting Steps:

• Check the power supply – Make sure the unit is plugged in and the outlet is working.
• Press the reset button – Most disposals have a red reset button on the bottom. Pressing it may restore power.
• Inspect the circuit breaker – If the disposal tripped a breaker, resetting it at the electrical panel may solve the problem.

If none of these solutions work, there may be an internal motor failure requiring professional repair.

2. Garbage Disposal Hums But Won’t Grind

A humming noise without movement usually means the unit is jammed.

How to Fix a Jammed Disposal:

• Turn off power – Always unplug the disposal or turn off the circuit breaker before attempting any repairs.
• Use a hex key – Most units have a small hex socket underneath. Insert an Allen wrench and turn it back and forth to free the jam.
• Manually remove blockages – Using pliers or tongs, remove any stuck food debris or foreign objects.

If the jam persists, the motor may be damaged, requiring professional service.

3. Garbage Disposal Is Leaking

Leaks can occur from different points in the system, including the sink flange, drain connections, or the disposal body itself.

Possible Causes and Fixes:

• Leaking from the top (sink flange): The mounting assembly may need tightening, or the plumber’s putty sealing the unit may have worn away.
• Leaking from the sides (drain connections): Loose or cracked pipes may need tightening or replacement.
• Leaking from the bottom: This usually means the internal seals are worn out, and the entire unit may need replacement.

4. Garbage Disposal Drains Slowly

If your disposal is running but draining slowly, a clog may be blocking the pipes.

How to Clear a Clogged Garbage Disposal:

• Flush with hot water and dish soap to break down grease buildup.
• Use a plunger to help push food particles through the drain.
• Avoid chemical drain cleaners – These can damage the disposal’s internal components.
• Try a baking soda and vinegar solution – Pouring baking soda followed by vinegar can help break up minor blockages.

If the clog persists, a plumber can clear deep blockages without damaging your pipes.

5. Bad Smells Coming from the Disposal

Food residue trapped in the disposal can cause unpleasant odors over time.

How to Get Rid of Garbage Disposal Odors:

• Run citrus peels through the unit – Lemon, orange, or lime peels can help freshen the system.
• Clean with baking soda and vinegar – This natural solution helps eliminate bacteria and grease.
• Flush with ice and salt – Grinding ice cubes and rock salt can help clean the blades and dislodge stuck debris.

When to Call a Professional for Garbage Disposal Repair

While many minor garbage disposal issues can be fixed with basic troubleshooting, some problems require professional intervention. Contact a plumber if you experience:

• Frequent resets or power failures – This could indicate electrical wiring issues.
• Persistent leaks from the unit’s base – If the disposal body is cracked, replacement is necessary.
• Constant clogs despite cleaning efforts – A deeper plumbing issue may be affecting the drainage system.
• Unusual grinding or rattling noises – These sounds could mean broken impellers or foreign objects stuck in the unit.

Preventative Tips to Keep Your Garbage Disposal Running Smoothly

• Avoid putting fibrous foods like celery, potato peels, and corn husks into the disposal.
• Never pour grease or oil down the drain, as they solidify and cause blockages.
• Use cold water when running the disposal to help solidify and grind food waste effectively.
• Run the disposal regularly to prevent rust and buildup inside the unit.
