What Causes Garbage Disposal to Malfunction?

Understanding what causes garbage disposal malfunctions can help you troubleshoot common issues. Garbage disposals are built to handle certain types of food waste, but overloading them or using them improperly can lead to breakdowns.

Common Garbage Disposal Problems

Garbage disposal jams and clogs are some of the most frequent issues homeowners face. These problems often arise when hard items like bones, fibrous vegetables, or grease are put down the disposal. When this happens, the garbage disposal motor may get stuck or overheat, causing a malfunction. Over time, these clogs can create severe blockages that restrict water flow, making your disposal inefficient.

Another common issue is garbage disposal odors, which occur when leftover food waste or moisture builds up inside the disposal unit. If not cleaned properly, it can lead to foul-smelling waste buildup, making your kitchen smell unpleasant.

Leaking garbage disposal is another issue that may indicate wear and tear or damage to the disposal’s components. Leaks can occur due to loose connections or cracks in the housing of the disposal, leading to water dripping onto your kitchen floor and causing potential water damage.

Signs Your Garbage Disposal is Failing

There are clear signs that your garbage disposal may be failing. If you notice any of the following, it's important to address the issue promptly:

• Unusual Noises: Grinding, rattling, or humming noises are all indicators that your garbage disposal may not be functioning properly. These sounds can indicate jammed components or a malfunctioning motor.
• Slow Draining: If your sink is draining slowly, it could be a sign of a clogged disposal. Over time, food waste can accumulate and block the drain, slowing down water flow.
• Leaks or Water Pooling: Leaks around the garbage disposal could be a sign of a damaged seal or pipe connection. If left unaddressed, leaks can lead to water damage under your sink.
• Foul Odors: Unpleasant smells coming from the disposal often result from food buildup, grease, or mold growing in hard-to-reach areas inside the unit.
• Failure to Turn On: If your garbage disposal doesn’t turn on, it could be due to electrical issues or a burnt-out motor. This is one of the most obvious signs that professional attention is needed.

5 Clear Signs Your Garbage Disposal Needs Repair

Recognizing the signs of a malfunctioning garbage disposal is key to preventing further damage and inconvenience. Here are the 5 clear signs your garbage disposal needs repair:

1. Strange Noises from Your Garbage Disposal

If your garbage disposal is making loud or unusual noises, it’s a clear indication that something is wrong. When you turn on the disposal and hear grinding, humming, or rattling sounds, these are usually signs that debris is blocking the mechanism or the garbage disposal motor is failing. A broken garbage disposal often makes these types of noises due to a stuck flywheel or motor failure.

If the noise persists after attempting to reset the unit, it's time to contact a professional plumber to inspect and repair the disposal.

2. Clogged or Jammed Disposal

A clogged garbage disposal is one of the most common issues homeowners face. Clogs occur when food debris, grease, or foreign objects block the drain or impeller. When a garbage disposal gets jammed, it becomes ineffective at grinding food waste, causing water to back up into the sink.

If your disposal is clogged, try turning off the power and using the reset button or an Allen wrench to dislodge the jam. However, if the clog persists or recurs frequently, you should consider a professional repair or replacement.

3. Leaks Around the Disposal Area

If you notice water pooling around your sink or disposal, leaking garbage disposal could be the cause. Leaks are typically caused by loose or damaged seals, cracked parts, or worn-out plumbing connections. Water leaks can lead to significant damage under your sink if not fixed immediately, resulting in mold growth and water stains.

For garbage disposal repair, a plumber will inspect the unit for any cracks or deteriorating seals and provide the necessary fixes.

4. Foul Odors from the Garbage Disposal

Foul odors from the disposal are another sign that your unit may need attention. Garbage disposal odors often result from food particles getting stuck in the grinding chamber or pipes. This buildup can lead to the growth of bacteria and mold, creating unpleasant smells.

To resolve this, clean your disposal with a citrus peel or garbage disposal cleaning solution. If the odors persist, it may be time to contact a professional for deep cleaning or repair.

5. The Garbage Disposal Won’t Turn On

If your garbage disposal doesn’t turn on despite pressing the reset button or flipping the switch, there could be an electrical issue or a garbage disposal motor failure. This is often a sign that the motor has burned out, or the unit has reached the end of its lifespan.

If the motor fails or the unit no longer turns on, it's time to call in a professional plumber to assess whether the unit needs replacing.

When Should You Repair vs. Replace Your Garbage Disposal?

Knowing when to repair and when to replace your garbage disposal is key to saving time and money. If your garbage disposal has experienced frequent breakdowns or is over 10 years old, it might be more cost-effective to replace it rather than continue repairing it.

The Lifespan of a Garbage Disposal

A typical garbage disposal lasts between 8 to 15 years, depending on usage and maintenance. If your unit is nearing the end of its lifespan and you’re constantly dealing with problems, garbage disposal replacement may be a better option.

Cost of Garbage Disposal Repair vs Replacement

When deciding whether to repair or replace your garbage disposal, consider the cost of repair. Repairs usually range from $100 to $300, depending on the issue. However, if the cost of repair approaches the price of a new disposal, or if the unit is outdated, replacing the unit might be a more economical solution.

You Need to Upgrade or Replace Your Home Plumbing

In some cases, your garbage disposal issues may stem from underlying plumbing problems. If your plumbing system is outdated or not up to standard, it can affect the functionality of your disposal. You need to upgrade or replace your home plumbing if your pipes are corroded, damaged, or unable to support the proper flow of waste from your disposal.

If you're encountering persistent drainage issues or low water pressure, it could be a sign that the plumbing connected to your garbage disposal needs an upgrade. A professional plumber can help identify whether a plumbing service is necessary before proceeding with repairs to your disposal unit.

How to Fix a Clogged Garbage Disposal: DIY vs Professional Help?

If your garbage disposal is clogged or jammed, you may wonder whether to attempt a DIY fix or call a professional. DIY garbage disposal repair can be an effective solution for minor clogs, but more complex issues may require a plumber’s expertise.

Steps to Unclog a Garbage Disposal

To fix a clogged garbage disposal, follow these steps:

• Turn off the power to the disposal for safety.
• Use an Allen wrench or plunger to loosen any debris.
• If the clog persists, check the drain pipe for obstructions.
• For more stubborn clogs, contact a professional plumber to clear the blockage.

If you're unsure about handling the issue yourself, garbage disposal repair services are available to help resolve more serious problems.

When to Call a Professional Plumber for Garbage Disposal Issues

If the clog or malfunction is beyond your DIY capabilities, it’s best to call a professional plumber. Plumbing service professionals have the tools and expertise needed to handle more complex problems, ensuring that your disposal is properly repaired or replaced.

Garbage Disposal Maintenance: Tips for Long-Term Care

Regular garbage disposal maintenance is essential to extend the lifespan of your appliance and prevent frequent repairs.

Regular Maintenance Steps

To keep your garbage disposal in optimal condition:

• Always run cold water while using the disposal to help solidify grease and prevent clogs.
• Avoid putting fibrous vegetables like celery and bones down the disposal, as they can jam the blades.
• Periodically clean the disposal using citrus peels or a garbage disposal cleaning solution to keep it fresh and free of odors.

By following these maintenance tips, you can reduce the need for costly repairs and extend the life of your garbage disposal.

Scheduling Professional Garbage Disposal Inspections

It’s also a good idea to schedule regular inspections by a professional plumber to ensure your garbage disposal is functioning properly. An inspection can catch potential issues early, saving you money on repairs in the long run.
