Common Garbage Disposal Issues

Garbage disposals help keep your kitchen clean and free of food waste. However, like all appliances, they can encounter issues over time. Understanding the common problems that can arise with your garbage disposal will allow you to take quick action and prevent further damage. 

At ServiceOne, our plumber garbage disposal experts are here to help resolve all of the issues you run into. Below, we discuss the most common garbage disposal problems and how ServiceOne's professional plumbing services can resolve these issues efficiently.

Clogs and jams

One of the most common issues that garbage disposals face is clogging or jamming. This usually occurs when something that shouldn’t be processed by the disposal gets caught in it, or when there’s a buildup of grease or other materials. When this happens, the disposal can make a humming sound or stop working altogether. A qualified plumber garbage disposal expert can help by safely removing the clog or jam and advising on best practices to prevent future occurrences.

Dull blades

Over time, the blades within your garbage disposal can become dull. This is especially common in older garbage disposals. Dull blades are less effective at grinding food waste, which can lead to clogs. If you notice that your garbage disposal is struggling to break down waste, or if it’s taking much longer than usual, it might be time to contact a professional. 


Leaks are another common problem with garbage disposals. They can occur at various points, such as where it connects with the sink, the dishwasher hose or the drainpipe. Left unchecked, these leaks can lead to water damage in your home. A plumber garbage disposal specialist from ServiceOne can accurately identify the source of the leak and perform the necessary repairs.


If your garbage disposal suddenly stops working, it might be due to overheating. This can happen if the disposal is used for an extended period or if a foreign object is lodged in it. Most units have a built-in safety feature that shuts off the motor when it overheats. In this case, after allowing the unit to cool down, you can usually reset it using the reset button. However, if the issue persists, it’s advisable to call a professional plumber to inspect the unit.

Foul odors

Sometimes, food particles can get trapped in the garbage disposal, leading to unpleasant odors. This issue can often be resolved by cleaning the unit with a mixture of ice cubes and a small amount of dish soap. If the smell persists, it might indicate a more serious issue like mold growth or a sewer line problem, in which case professional help should be sought.
