Troubleshooting Your Garbage Disposal

Before You Start: Safety First

Always turn off the power to the garbage disposal at the circuit breaker before attempting any repairs. This is crucial to avoid electrical shock.

Step 1: Check the Reset Button

Most garbage disposals have a reset button located on the bottom. If it’s tripped, press it to reset. If the disposal still doesn’t work, move on to the next step.

Step 2: Clear the Jam Manually

  • Unplug the disposal: Double-check that the power is off at the breaker.
  • Look inside: Use a flashlight to see if any objects are visible in the disposal chamber.
  • Remove obstructions: Use tongs or pliers to carefully remove any debris. Never use your hands.

Step 3: Crank the Motor Manually

  • Locate the hex socket: Most disposals have a hex socket on the bottom.
  • Use an Allen wrench: Insert the wrench into the socket and turn it back and forth. This should help dislodge any stuck debris.

Step 4: Baking Soda and Vinegar

  • Pour down the drain: Combine 1/2 cup baking soda and 1/2 cup vinegar. Let it sit for a few minutes.
  • Flush with hot water: Run hot water down the drain to rinse away the mixture.

Step 5: Call a Professional

If the above steps don’t work, it’s time to call a plumber. They have the tools and expertise to diagnose and fix more complex problems.

Diagnosing the Jam

When a garbage disposal is jammed, identifying the issue is crucial before attempting any repairs. This section covers how to pinpoint the problem, perform safety checks, and prepare the necessary tools.

Identify the Problem

First, listen closely. If the disposal hums but does not grind, the blades might be stuck. If there is no sound, the power might be off or the device might need resetting.

Next, carefully peek down the drain with a flashlight. Look for visible obstructions. Avoid using your hands to inspect the inside of the disposal.

Finally, press the reset button usually found underneath the unit. If this doesn’t work, more steps are needed to find the issue.

Safety Precautions

Always prioritize safety to avoid injury. Ensure the garbage disposal is off before you begin. It’s not enough to rely on the wall switch; unplug the unit or turn off the circuit breaker.

Do not insert your hand into the disposal. Use tools like pliers or tongs to remove stuck objects. Always keep your hands clear to reduce risk.

If unsure about any step, consider calling a professional to avoid hazards.

Tools and Materials

Gather the right tools to effectively address the jam. You will need:

Allen wrench or disposal wrench

  • Used to manually turn the blades and free the jam.

Pliers or tongs

  • Helpful for removing visible obstructions without using your hands.


  • Essential for looking inside the disposal to spot and identify jams.

Wooden spoon

  • Can nudge stuck items but don’t use it for heavy-duty jobs.

By being prepared and following these straightforward steps, diagnosing and fixing a jammed garbage disposal becomes manageable and safe.
