5 Common Garbage Disposal Problems And How To Fix Them

1. Jammed Disposal

A jammed garbage disposal is one of the most common issues homeowners encounter. This typically happens when large or hard objects, such as bones, fruit pits, or non-food items, get stuck in the blades, preventing them from rotating. When the disposal is jammed, you might hear a humming sound when you turn it on, but the blades won’t move, indicating that something is blocking their rotation.

To fix a jammed disposal, start by turning off the power to the unit to avoid any accidents. Using a flashlight, look inside the disposal to identify the object causing the jam. You can use pliers or tongs to carefully remove the obstruction. Many disposals also have a manual reset button or an Allen wrench slot at the bottom of the unit, which can be used to manually rotate the blades and dislodge the jam. Once the obstruction is cleared, restore power and test the disposal to ensure it’s working properly.

Preventing jams in the future involves being mindful of what you put down at your disposal. Avoid disposing of large, hard objects, fibrous foods like celery or corn husks, and items like eggshells that can accumulate and cause clogs. Running cold water while the disposal is in use and for a few seconds afterward can also help flush food particles through the system.

2. Clogged Drain

Clogged drains are another frequent problem with garbage disposals, often caused by a buildup of food particles, grease, or fibrous materials that accumulate in the pipes. When the drain is clogged, water might back up into the sink, creating a mess and preventing the disposal from functioning properly. This issue can be particularly frustrating because it can lead to slow drainage and unpleasant odors in your kitchen.

To clear a clogged drain, start by turning off the disposal and removing any standing water from the sink using a cup or bucket. You can then try using a plunger to dislodge the clog by creating a seal over the drain and plunging up and down several times. If this doesn’t work, a mixture of baking soda and vinegar can help break down the blockage. Pour the baking soda into the drain, followed by vinegar, and allow it to sit for 10-15 minutes before flushing with hot water. In more stubborn cases, a plumber’s snake or auger might be necessary to reach deeper clogs.

Preventing clogs involves being careful about what goes down the disposal and using plenty of water to wash down food particles. Regularly running the disposal with cold water can help keep the pipes clear, and avoiding the disposal of grease, oil, and fibrous materials will reduce the risk of clogs.

3. Leaking Disposal

A leaking garbage disposal can be a serious issue, leading to water damage in your kitchen cabinets and potentially costly repairs. Leaks can occur for several reasons, including loose connections, worn-out seals, or cracks in the disposal unit itself. Depending on where the leak is coming from, it may be a simple fix or require more extensive repairs.

To fix a leaking disposal, first, identify the source of the leak. Check the connections between the disposal and the sink drain, the dishwasher hose, and the disposal’s mounting flange. If the connections are loose, tighten them using a wrench. If the leak is coming from the bottom of the unit, it may be due to a worn-out internal seal or a crack, which usually means the disposal will need to be replaced. For leaks around the sink flange, resealing it with a plumber’s putty can often solve the problem.

Preventing leaks involves regular maintenance of your disposal, such as checking the connections and seals periodically. Avoid overloading the disposal with large amounts of food waste, and be mindful of its age—most disposals have a lifespan of about 10-15 years, after which they may need to be replaced to avoid frequent leaks and other issues.

4. Unusual Noises

Unusual noises coming from your garbage disposal are often a sign that something is wrong. Grinding, rattling, or humming sounds can indicate various issues, from loose parts to foreign objects lodged in the disposal. These noises should not be ignored, as continuing to use the disposal in this condition could cause further damage.

To address unusual noises, first, turn off the disposal and disconnect the power to prevent any accidents. Use a flashlight to look inside the disposal and see if there are any foreign objects, such as utensils, bones, or other debris. If you find anything, carefully remove it with pliers or tongs. If the noise persists after removing any visible obstructions, the problem could be due to loose or worn-out parts inside the disposal. In this case, it may be necessary to consult the manufacturer’s manual or contact a professional to inspect and repair the unit.

Preventing unusual noises involves being cautious about what you put into the disposal. Avoid grinding non-food items, and regularly check the disposal for any loose parts that could cause problems. If your disposal is older and frequently makes strange noises, it may be time to consider replacing it with a newer model.

5. Disposal Won’t Turn On

If your garbage disposal won’t turn on, it can be a frustrating experience, especially if you’re in the middle of cleaning up after a meal. This problem is usually caused by an electrical issue, such as a tripped circuit breaker, a blown fuse, or a faulty switch. It can also occur if the disposal’s internal motor has overheated and triggered a safety mechanism that shuts it down.

To fix a disposal that won’t turn on, start by checking the power source. Ensure that the disposal is plugged in and that the circuit breaker hasn’t tripped. If everything appears to be in order, locate the reset button on the bottom of the disposal unit and press it. This button often resolves issues caused by an overheated motor. If the disposal still doesn’t turn on, the problem might be with the wall switch or the disposal’s internal wiring, in which case you may need to consult an electrician.

Preventing this issue involves using the disposal according to the manufacturer’s guidelines and avoiding overloading it with large quantities of food waste. Regularly running the disposal with cold water helps keep it in good working order, reducing the likelihood of motor strain and electrical problems. If your disposal is older and frequently fails to turn on, it might be time to invest in a new, more reliable unit.
