How to Troubleshoot Your Garbage Disposal

Garbage disposals are valuable kitchen appliances that make food waste disposal more convenient. However, like any mechanical device, they can encounter problems from time to time. As the go-to plumber across The North Shore and Merrimack Valley of Massachusetts, Maffei Services has repaired a full range of garbage disposal problems. In this helpful article, our plumbers provide you with tips on how to troubleshoot common issues with your garbage disposal and when it’s time to call in our professionals for help.

Before You Begin

Before diving into troubleshooting, it’s crucial to prioritize safety when dealing with your garbage disposal. Here are some essential safety measures to follow:

  1. Turn Off the Power: Always disconnect the power supply to your garbage disposal before attempting any troubleshooting or maintenance. This can typically be done by switching off the circuit breaker or unplugging the unit.
  2. Avoid Putting Hands Inside: Never put your hand or any object inside the disposal chamber while troubleshooting, even if it’s disconnected from power. Use appropriate tools instead.
  3. Use Proper Lighting: Adequate lighting in the area will help you see what you’re doing and prevent accidents.

Common Garbage Disposal Problems and Solutions

Now, let’s explore some common garbage disposal issues and how to troubleshoot them:

  1. Disposal Doesn’t Turn On: If your garbage disposal isn’t responding when you flip the switch, it may be due to a power issue. Start by checking if the unit is plugged in or if the circuit breaker has tripped. If power isn’t the problem, the reset button on the disposal may need to be pressed. This button is typically located on the bottom of the unit. If it still doesn’t work, it could be a wiring issue or a faulty switch, requiring professional assistance.
  2. Jamming or Grinding Noise: If you hear a grinding noise or the disposal seems stuck, it’s likely jammed. Turn off the power and use a disposal wrench or an Allen wrench (insert it into the hole at the bottom of the unit) to manually rotate the disposal blades and dislodge the obstruction. Once freed, restore power and test the disposal.
  3. Slow Draining or Clogged Disposal: Slow drainage or a clogged disposal often result from food debris or grease buildup. Start by turning off the disposal and running cold water down the drain for a few minutes to flush out any remaining debris. If it persists, you can try using a plunger or a disposal cleaner specifically designed to break down food particles and grease. Avoid using harsh chemicals, as they can damage the disposal and pipes.
  4. Leaking Disposal: A leaking disposal typically indicates a loose or damaged seal. Inspect the connections between the disposal and the sink. Tighten any loose screws or bolts. If the leak persists, it may require replacing the seal or other components, which should be done by a professional plumber.
  5. Foul Odors: Foul odors emanating from the disposal can be resolved by cleaning it thoroughly. Start by turning off the power and cleaning the rubber baffle (if your disposal has one). Then, grind ice cubes and citrus peels in the disposal to eliminate odors. You can also pour a mixture of baking soda and vinegar down the drain and let it sit for about 15 minutes before flushing it with hot water.
  6. Continuous Resetting: If you find yourself needing to reset the disposal frequently, it’s likely due to overheating. Overheating can occur when the disposal is used for an extended period or when it’s jammed. Allow the unit to cool down, then press the reset button. Avoid overloading the disposal and ensure it’s used within its capacity.
  7. Unusual Noises or Vibrations: If your disposal is making unusual noises or vibrating excessively, it could be due to loose components or worn-out blades. Turn off the power and inspect the disposal for any loose screws or objects stuck in the unit. If the problem persists, it may be time to replace the disposal.

When to Call a Professional

While many garbage disposal issues can be resolved with DIY troubleshooting, there are situations where professional intervention is necessary. Consider calling the plumbers at Maffei Services in the following scenarios:

  1. Persistent Clogs: If you’ve tried all the recommended methods for unclogging your disposal and the problem persists, a plumber can use specialized tools to clear stubborn blockages.
  2. Leak Repairs: If your disposal is leaking and tightening connections hasn’t resolved the issue, it’s best to have a plumber assess the problem and make necessary repairs.
  3. Electrical Issues: If you suspect electrical problems with your disposal, such as a malfunctioning switch or wiring, it’s essential to hire a licensed electrician or plumber to address these issues safely.
  4. Replacement: When your garbage disposal is old, damaged beyond repair, or no longer functioning efficiently, it may be time for a replacement. A plumber can help you select a suitable replacement unit and install it correctly.

Troubleshooting your garbage disposal can often resolve common issues and keep it running smoothly. Remember to follow safety precautions and turn off the power before attempting any repairs. However, when in doubt or when faced with more complex problems, it’s best to enlist the professional plumbers at Maffei Services.
