What are the Warning Signs of a Failing Garbage Disposal in San Diego?

June 17, 2025

A garbage disposal is a kitchen convenience many San Diego homeowners rely on daily—until it stops working properly. When your garbage disposal begins to fail, it can lead to foul odors, clogged pipes, and even damage to your plumbing system. Knowing the early warning signs of a failing garbage disposal can help you take quick action and avoid bigger problems.

At Fox Plumbing, we’ve spent over 40 years helping San Diego residents with fast-response emergency plumbing services, including garbage disposal repairs and replacements. Here’s what you need to know.

1. Strange or Persistent Noises

If your garbage disposal is making unusual grinding, rattling, or humming sounds, it could be a sign that internal components are worn out, loose, or broken. A metal object like a spoon accidentally caught inside can make noise temporarily, but persistent or loud noises often indicate internal mechanical failure.

2. Frequent Resets

Garbage disposals come with a reset button that protects the motor from overheating. However, if you’re pressing the reset button often, that’s a red flag. Frequent resets suggest the motor is struggling or the unit is nearing the end of its life.

3. Foul Odors That Don’t Go Away

It’s normal for some odor to build up over time if food particles get trapped, but persistent smells that don’t improve with cleaning could mean food is not grinding properly and is rotting in hidden parts of the unit. This can lead to hygiene issues and even attract pests.

4. Poor Performance or Slow Draining

If your sink drains slower than usual after using the garbage disposal, or if the unit is taking longer to grind food waste, your disposal could be clogging or losing power. Buildup of grease, fibrous food, or even wear on the grinding components can reduce performance.

5. Leaks Under the Sink

Leaks from the garbage disposal often go unnoticed until there’s water damage or mold under the sink. These leaks may come from worn seals, cracks in the casing, or loosened connections. If you notice pooling water or moisture, it’s time to have it inspected immediately.

6. Unit Won’t Turn On

A disposal that won’t start at all may point to a blown circuit, a tripped breaker, or a dead motor. Sometimes, this is an electrical issue, but if power is getting to the unit and it’s still not functioning, the motor may have failed completely.

7. Unusual Vibrations or Shaking

While some vibration is normal, excessive shaking could indicate loose mounting or imbalanced internal parts. This not only puts stress on the unit but can also affect nearby plumbing connections and cause long-term damage if not addressed.

8. Visible Rust or Cracks

Over time, water exposure can lead to rusting and deterioration, especially in older units. Cracks in the outer housing or rust inside the grinding chamber can eventually lead to leaks and loss of function.

Don’t Ignore the Warning Signs

In a busy San Diego household, it’s easy to overlook subtle changes in how your garbage disposal performs. But small problems can become major plumbing issues if left unaddressed. From clogged drains to flooding under your sink, a failing disposal affects more than just convenience—it can threaten the health of your plumbing system.
