Why Is My Garbage Disposal Making Strange Noises?

Youmna Rehman

Garbage disposals are a blessing in the kitchen—until they start making unsettling noises. Whether it’s a rattling, humming, or grinding sound, strange noises from your garbage disposal often signal an issue that needs attention. Let’s dig into all the possible reasons behind those bizarre sounds, how you can fix them, and the best ways to maintain your garbage disposal.


"DIY Garbage Disposal Repair: What You Can and Can’t Do"


Reasons Your Garbage Disposal Is Making Strange Noises


1. Foreign Objects Lodged in the Disposal

Sometimes, a stray utensil or a hard item like a bone can find its way into the disposal. These foreign objects clash with the impellers, creating a loud rattling noise. If the noise persists, it’s essential to turn off the disposal immediately to prevent any further damage. Reaching into the disposal can be dangerous, so it’s wise to use tongs or a similar tool to retrieve the offending item. Always ensure the unit is unplugged or the circuit breaker is turned off before attempting any removal.


2. Loose or Damaged Blades

Over time, the disposal's internal components, such as blades, can loosen or get damaged. This can result in clunking or grinding sounds when the disposal is running. If you notice these noises, it’s important to address the issue promptly to prevent further damage. A loose blade can lead to inefficient operation, making it harder for the disposal to grind food waste effectively. In some cases, this may also cause the motor to overheat, potentially leading to a complete breakdown of the unit.


3. Worn-Out Bearings or Motor Issues

If your garbage disposal hums but doesn’t grind, the motor bearings might be worn out. This issue often indicates the disposal is nearing the end of its lifespan. In such cases, it’s advisable to first unplug the unit to ensure your safety before inspecting it further. Check for any jammed debris that may be obstructing the blades; often, a simple removal of the obstruction can restore functionality. If the disposal still hums after addressing potential jams, it might be time to consider a replacement.


4. Clogs in the Drain Pipe

A clog in the pipe connected to your disposal can create a gurgling or bubbling sound as water tries to push through the obstruction. This sound can be indicative of a blockage that needs addressing. Over time, food particles, grease, and other debris can accumulate in the pipes, preventing water from flowing freely. If left unresolved, this can lead to more serious issues, such as backups or even complete stoppages in your plumbing system.


5. Loose Mounting Screws or Components

A poorly mounted garbage disposal can vibrate excessively, producing rattling or shaking noises. This vibration can not only be bothersome but may also indicate that the unit is not securely fastened to the sink. If left unaddressed, these issues could lead to further complications, such as leaks or even damage to the plumbing. Proper mounting is crucial for the efficient operation of a garbage disposal.


6. Broken Flywheel or Jammed Parts

If the flywheel inside the disposal is jammed or broken, it may result in grinding or screeching noises as it struggles to move. .In such cases, it's crucial to address the issue promptly to avoid further damage. First, ensure the disposal is unplugged or the power is turned off to prevent any accidents while inspecting it. Use a flashlight to look inside and check for any visible blockages; items like bones, silverware, or fibrous materials can often get lodged in the mechanism. If you identify any debris, carefully remove it with tongs or a similar tool, being cautious not to damage the disposal's blades.


7. Improper Installation

If the disposal was installed incorrectly, you might hear irregular noises due to misalignment or poor connections. In addition, you may notice that the disposal struggles to effectively grind food waste, resulting in frequent jams or backups in the drain. This can lead to unpleasant odors and even potential plumbing issues if left unaddressed. It's crucial to check for any loose screws or clamps that could be causing the unit to vibrate or rattle excessively. 


How to Fix a Noisy Garbage Disposal


1. Remove Foreign Objects Safely

Turn off the power to your garbage disposal (unplug it or switch off the circuit breaker). Use pliers or tongs to carefully remove any foreign objects. Never use your hands! If you encounter stubborn clogs, fill the sink with a bit of water and use a plunger to create suction, which can help dislodge the blockage. Avoid using harsh chemicals, as they can damage the disposal and pipes. Instead, consider a mixture of baking soda and vinegar for a natural cleaning solution; pour half a cup of baking soda followed by half a cup of vinegar into the disposal, let it fizz for a few minutes, then rinse thoroughly with hot water.


2. Tighten or Replace Loose Blades

Inspect the blades and other components for looseness. Tighten screws or bolts where needed. If the blades are damaged, consider contacting a professional for replacement. If the blades are damaged, consider contacting a professional for replacement and maintenance. Make sure to clean the blades using a soft cloth to remove any dust or debris that may have accumulated. Regular cleaning will help maintain optimal performance and prolong the lifespan of the device.


3. Clear the Flywheel and Reset

Use an Allen wrench to rotate the flywheel manually from the bottom of the unit. This can help dislodge jams. Don’t forget to press the reset button afterward! If the flywheel remains unresponsive after attempting to free it, consider checking for any debris or blockages around the unit. Carefully inspect the area and remove any foreign objects that may be obstructing the mechanism. It’s essential to ensure that the motor is unplugged before performing this check to ensure your safety.


4. Unclog the Drain

For clogs, use a plunger or a natural solution of baking soda and vinegar to clear the obstruction. Avoid chemical drain cleaners, as they can damage the disposal. If the clog persists after trying these methods, consider using a plumber's snake for a deeper clearing. Insert the snake into the drain and twist it to break up stubborn blockages. Be patient and gentle to avoid damaging the pipes. Additionally, regular maintenance can help prevent future clogs. Pouring a mixture of hot water and dish soap down the drain once a month can help keep grease buildup at bay. Remember, keeping the disposal clean and free of large food particles is key to maintaining its efficiency.


5. Inspect Mounting Hardware

Check the mounting screws and brackets to ensure the disposal is securely attached. Tighten any loose components to reduce vibrations and noise. Next, inspect the power cord for any signs of wear or damage. A frayed or damaged cord can lead to safety hazards or malfunctions. If you notice any issues, consider replacing the cord before proceeding. Additionally, check the drainage connection; ensure that it’s properly aligned and tightly secured to prevent leaks.


6. Address Motor Issues

If you suspect motor or bearing problems, it’s best to replace the disposal. Professional inspection can confirm whether repairs are worth it or if a new unit is needed. Additionally, consider the age of your disposal unit. Most disposals have a lifespan of about 10 to 15 years. If your unit is approaching or has surpassed this range, investing in a new model might be more economical in the long run, even if the current issue seems repairable.


7. Recheck Installation

If improper installation is the culprit, you might need to realign the unit or call a plumber to fix the issue properly. If the problem persists even after realigning, it's crucial to inspect the surrounding plumbing for any underlying issues that may be contributing to the malfunction. Look for leaks, corrosion, or blockages that could be affecting performance. Additionally, double-check all connections to ensure they are secure and that no fittings have come loose over time.


DIY Tips for Fixing Garbage Disposal Noise

Reset First: Always try the reset button before attempting major fixes.

Use an Allen Wrench: Most disposals come with a hex key for manual flywheel rotation to fix jams.

Clean It Regularly: Run ice cubes or citrus peels through the disposal to clean the blades and eliminate odors.

Avoid Harsh Chemicals: Stick to natural solutions for cleaning and unclogging.


How Can I Maintain My Garbage Disposal?

1. Use Cold Water While Running

Cold water helps solidify grease, making it easier to chop and prevent clogs.

2. Avoid Hard or Fibrous Foods

Keep bones, fruit pits, and fibrous veggies like celery out of your disposal to avoid jams.

3. Clean the Disposal Weekly

Pour a mixture of baking soda and vinegar down the disposal weekly to break down grease and food particles.

4. Run the Disposal Regularly

Even if you don’t use it often, running your disposal every few days prevents rust and obstructions.

5. Inspect for Wear and Tear

Check the unit periodically for loose parts, cracks, or other damage. Fixing small issues early can extend its life.

6. Don’t Overload It

Feed food scraps gradually to avoid overwhelming the motor and causing jams.

DIY Drain Maintenance Tips to Prevent Future Clogs

by Youmna Rehman • 1 May 2025
Clogged drains are one of those household issues that always seem to show up at the worst possible time. Whether it’s a backed-up kitchen sink during dinner prep or a slow-draining shower when you're rushing for work, they’re inconvenient, unpleasant, and often expensive to fix if left unattended. The good news? With a bit of regular care and a few simple techniques, you can avoid most clogs before they start. DIY drain maintenance isn’t just a reactive fix—it’s a proactive approach that saves time, money, and stress. Think of it like brushing your teeth. You don’t wait for a cavity; you clean daily to prevent one. Drains work the same way. Let’s dive into the common causes, smart solutions, and everyday habits that will keep your plumbing flowing freely. Benefits of Having an Expansion Tank Installed in Your Home What Causes Drains to Clog in the First Place? Understanding the problem is the first step to preventing it. Drains clog because of everyday use—but not always in ways we notice right away. In the kitchen, grease, oil, and food scraps stick to pipe walls, harden, and build up over time. In bathrooms, hair, soap scum, and toothpaste form stubborn tangles that slow water flow. Laundry drains face detergent residue and lint. Even so-called “flushable” wipes can wreak havoc in toilet pipes. The challenge is that most of this buildup is gradual. You may not notice a problem until the water starts pooling or smells start rising—and by then, a full-blown clog could be just around the corner. Step-by-Step: How to Maintain Your Drains at Home Step 1: Flush Your Drains Weekly with Hot Water One of the easiest habits you can adopt is flushing your drains with hot water once a week. This helps melt away minor grease deposits and dislodge small bits of debris before they can build up. Simply boil a kettle of water and pour it slowly down your drain. For kitchen sinks, you can follow it with a squirt of dish soap to cut through any residual grease. Step 2: Use a DIY Baking Soda and Vinegar Cleanse This old-school method is a favorite for a reason—it works. Once a month, pour half a cup of baking soda down the drain, followed by one cup of vinegar. Let it sit and fizz for 15 to 30 minutes, then flush with boiling water. This mixture helps break down organic material and neutralize odors without using harsh chemicals. It’s especially useful for bathroom sinks and shower drains where buildup tends to be slow but persistent. Step 3: Install Drain Strainers or Hair Catchers Mechanical prevention is often the most effective. Installing strainers or mesh covers over your drains can dramatically reduce the amount of debris entering your pipes. In kitchens, they stop food scraps. In bathrooms, they catch hair. They’re inexpensive, easy to clean, and one of the smartest tools in your DIY maintenance kit. Step 4: Clean the Stoppers and Covers Drain stoppers in bathroom sinks and tubs collect grime over time. Every couple of weeks, remove and clean them thoroughly with hot water, an old toothbrush, and soap. This prevents buildup at the entry point of your drain and keeps water flowing smoothly. Step 5: Use Enzyme Cleaners Monthly Enzyme-based drain cleaners are a safe, eco-friendly way to maintain your plumbing. These cleaners use natural bacteria and enzymes to digest organic material in your pipes. Unlike chemical alternatives, they won’t corrode your pipes or kill beneficial bacteria in septic systems. Regular monthly use keeps your drains clean and odor-free. The Risks of Ignoring Drain Maintenance Many people wait until there’s a problem to think about their drains. But ignoring routine maintenance carries hidden risks. Minor clogs can turn into major backups, leading to overflows, water damage, and costly plumber visits. If you’re dealing with old pipes, recurring blockages can weaken their integrity and eventually cause leaks or breaks. Additionally, standing water from partial clogs creates a breeding ground for mold and bacteria, which can affect your indoor air quality. Odors, slow drainage, and constant plunging become part of your everyday routine—and that’s not a habit anyone wants. By contrast, maintaining your drains regularly prevents emergencies and keeps your home healthy and hygienic. Challenges You Might Face With DIY Drain Maintenance DIY drain care is effective, but it comes with a few challenges. First, it requires consistency. One-time fixes won’t cut it. Just like you wouldn’t brush your teeth once and forget it, drain maintenance has to be a habit. Second, you may encounter deeper problems that simple DIY methods can't solve—like tree root intrusion, damaged pipes, or long-standing grease clogs. In these cases, professional tools like snaking or hydro jetting may be necessary. Finally, not all products work for every type of drain. Enzyme cleaners may be perfect for organic buildup but won’t help with mineral deposits or foreign objects. You’ll need to understand your system and use the right tools at the right time. Expert Advice: What Plumbers Recommend for Homeowners Most plumbers agree on one thing: Prevention is cheaper and easier than repairs. They often recommend homeowners adopt a monthly maintenance routine and take steps to avoid the most common clogging culprits. Grease is one of the worst offenders. Never pour it down the drain, even if you flush it with hot water. Instead, collect it in a jar and dispose of it in the trash. Similarly, hair may seem harmless, but it binds with soap and forms heavy clumps that are hard to dislodge. Experts also recommend keeping a plunger and drain snake handy for minor clogs. These manual tools are your first line of defense and often solve problems without the need for chemicals or a professional visit. Preventive Habits That Make All the Difference Incorporating small habits into your routine can have a big impact. Run hot water for a few seconds after using the sink to help push residue through. Don’t treat your garbage disposal like a trash can—avoid fibrous foods like celery, eggshells, and coffee grounds. Always dispose of hygiene products in the trash, no matter what the label says. And when in doubt, install a catch-all filter. By combining these habits with monthly enzyme treatments and occasional deep cleaning, you can keep your entire drain system running like new. Conclusion: Stay Ahead of Clogs with Simple, Smart Maintenance Taking care of your drains doesn’t require fancy tools or a plumber on speed dial. It’s about adopting a mindset of prevention and following through with simple, consistent actions. From flushing with hot water to monthly enzyme cleanings and mindful kitchen habits, DIY drain maintenance is both achievable and impactful. By investing just a little time each week, you can save yourself the frustration, cost, and mess of clogged pipes later on. So start today—your future self (and your plumbing) will thank you
