Garbage Disposal Not Working? Here's How to Fix Common Issues

Garbage disposals are convenient and effective plumbing appliances in most households globally. While a functioning system is crucial for maintaining a clean and functioning kitchen, issues can arise that disrupt operations. As a homeowner, understanding the common garbage disposal issues and how to fix them is crucial to keeping your appliance in optimal condition. That is where Rooter Man comes in as your trusted plumbing service provider. We leverage extensive knowledge and experience to address your specific needs and share pertinent information to help you troubleshoot issues before they escalate. Let’s look at some of the common garbage disposal problems and solutions.

Clogged and Slow Drains

Garbage disposal units undergo a lot of abuse throughout their lifespan. From grease and oils to eggshells and other solid food particles, a lot of waste can accumulate in your drains. These materials stick together and grow over time, obstructing water flow. In the case of a severe blockage, you may experience backups.

The best way to fix this problem is to prevent it. Avoid putting food waste in the disposal and run cold water regularly while it’s operating. If you experience a clog, plunging or store-bought cleaners can help. However, these DIY solutions only offer temporary relief. With that said, it is advisable to schedule routine inspections with a professional plumber in Altadena, CA to ensure smooth-flowing drains all year round.

Strange Noises

Another noticeable sign you need garbage disposal repair is strange noises. If you hear rattling, grinding, or humming when your disposal is running, something is wrong. Check the blades to see if bones, silverware, or other hard objects are stuck, as they can cause the blades to break and malfunction.

Before troubleshooting weird noises, turn off and unplug the disposal to avoid injuries and other safety hazards. Use a flashlight to look inside your unit and remove any objects that shouldn’t be there before turning it back on. If the noises persist, then chances are the blades are damaged and may require repair or replacement.

The Disposal Won’t Turn On

Nothing is more frustrating than a disposal unit that won’t start. While this is a common issue, it can indicate an overload, electrical issues, or a failing motor. The most common culprit of electric-related issues is a tripped circuit breaker, while overloads occur mainly because of putting too much material at once.

Check if the appliance is plugged in and if the breaker has tripped. If your disposal unit has a reset button, press it and turn it on again. This usually resolves the problem, but if your unit doesn’t turn on, there might be a problem with the internal wiring or motor. These are complex issues that require the expertise of a plumber.

Leaking

A leaking garbage disposal is inconvenient and causes damage to flooring and cabinetry. Leaks often occur at hose connections, sink flanges, or seals, indicating worn-out gaskets or improperly installed lines. Additionally, old components are susceptible to leaks, prompting a complete garbage disposal replacement.

Inspect the disposal to locate the source of the leak and tighten loose connections. If the problem persists, replace the gaskets and hire a plumbing service provider to check for broken or worn parts. While leaks can go undetected for a long time, neglecting timely repairs can lead to water damage and costly repairs.
