The putrid smell hit me first. Then, the unsettling silence. My trusty garbage disposal had given up the ghost, leaving a mountain of food scraps in the sink. It’s a frustrating experience, but don’t worry! This guide will walk you through troubleshooting your garbage disposal, helping you understand the common causes and solutions, potentially saving you the cost of a plumber.
Understanding Common Garbage Disposal Issues
This section will cover the most frequent problems encountered with garbage disposals, ranging from simple clogs to more serious motor malfunctions. We’ll explore effective DIY solutions and when it’s best to call a professional.
Clogs and Jammed Impellers
- Foreign Objects: A common cause is the accidental disposal of non-food items like bones, silverware, or fibrous materials. These can jam the impeller, the rotating part that grinds the waste. Removing these requires careful inspection and sometimes specialized tools.
- Overloading: Putting too much waste into the disposal at once can overwhelm its capacity and lead to a jam. Always add waste gradually and allow sufficient time for grinding.
- Food Buildup: Over time, food particles can accumulate on the impeller and chamber walls, reducing efficiency and eventually leading to a clog. Regular cleaning is essential.
For example, a friend of mine jammed her disposal by trying to grind down an entire chicken carcass. After several attempts at resetting it, she finally had to call a plumber who retrieved the bones and dislodged the blockage.
Motor Problems
- Overheating: Continuous use or grinding tough materials can overheat the motor, causing it to trip the thermal overload protector. This is a safety mechanism that prevents damage to the motor. Allowing it to cool down is typically sufficient.
- Burned-out Motor: In cases of severe overheating or overloading, the motor can burn out, requiring professional repair or replacement. A burnt-out motor will usually not even hum.
- Wiring Issues: Loose or damaged wiring can interrupt the power supply to the motor. Checking the connections is a crucial troubleshooting step. However, this should only be done by someone familiar with electrical work, or a qualified professional.
A burnt-out motor often presents itself with a complete lack of sound when you activate the unit. There’s nothing to be done other than getting a professional repair or replacement.
Leaks and Water Damage
- Loose Connections: Leaks are frequently caused by loose or worn-out seals around the disposal unit. These seals need to be replaced periodically.
- Damaged Disposal: Sometimes, the disposal unit itself might be damaged, leading to leaks. This might require a replacement.
- Improper Installation: If your garbage disposal wasn’t installed correctly, leaks are more likely. Check to ensure everything is properly sealed.
Water leaking from the disposal is a serious issue, often necessitating professional intervention because it can quickly escalate into water damage. One case I know of involved a leak that caused damage to the cabinets underneath the sink, resulting in a costly repair.
Troubleshooting Your Garbage Disposal
This section details the steps to take when your garbage disposal stops working, focusing on practical solutions you can implement at home.
Resetting the Garbage Disposal
- Locate the Reset Button: Most garbage disposals have a small reset button, usually located on the bottom. This button is typically red.
- Press and Hold: Press and hold the reset button for about 15-20 seconds, allowing the thermal overload protector to reset.
- Test the Disposal: Turn on the disposal to see if it works. If not, it may require further troubleshooting steps.
Clearing a Clog
- Turn Off Power: Ensure that the garbage disposal is turned off and the power switch at the breaker box is off.
- Use Pliers or Tongs: Use tongs or pliers to carefully remove any visible obstructions. Avoid using your hands to prevent injury.
- Flush with Water: Turn the power back on and flush the disposal with a mixture of hot water and dish soap to clear any remaining particles.
Using a Wrench to Free a Jammed Impeller
If resetting and simple clearing doesn’t solve the problem, and you suspect a jammed impeller, you may need a wrench to try and manually free the unit. Consult your disposal’s manual as this method is dependent on your specific model.
When to Call a Plumber
This section will guide you on when to call a plumber. It’s crucial to know your limits and when a professional is necessary.
Severe Motor Problems
If the motor is making strange noises (grinding, humming), or consistently fails to start after trying all the self-help options, it’s time to consult a plumber.
Persistent Leaks
Leaks are a sign of potential damage to the unit or incorrect installation. These can lead to water damage, mold growth, and higher repair costs later. A plumber can accurately diagnose the source of the leak and repair it promptly.
Electrical Issues
Unless you’re comfortable working with electricity, don’t attempt to troubleshoot electrical problems with your garbage disposal. This is best left to a qualified professional to prevent electric shock and further damage.
Debunking Garbage Disposal Myths
Myth 1: You can put anything down the garbage disposal.
This is false. Avoid hard materials like bones, pits, and fibrous vegetables which can damage the blades.
Myth 2: Running cold water is sufficient.
Hot water helps to melt grease and better flush the system.
Myth 3: A slow disposal is always a sign of a serious problem.
A slow disposal could be caused by minor clogs or a build-up of food waste, which may be easily remedied with a thorough cleaning and flushing.
