Signs of a Blocked Garbage Disposal

Most people do not notice a problem until their garbage disposal stops working altogether. Garbage disposal troubleshooting begins with knowing the signs of trouble.

Slow Water Drainage

A blocked garbage disposal can cause the water in the drain to drain slowly or become completely clogged. This could mean food or debris has become tightly packed in the drainpipe.

Humming Sounds Without Movement

A humming sound without movement indicates the blades have become jammed. It could also mean the motor is attempting to spin but can’t because of a malfunction or blockage.

Foul Odors Coming From the Unit

If you experience smells from the garbage disposal, built-up food has begun decomposing in the disposer and the line. Our garbage disposal cleaning tips can help stop the odors.

Frequent Reset Button Trips

If your garbage disposal resets often, this is a clear sign that there are problems. Frequent resetting could mean motor issues, overheating, or wiring problems. If your garbage disposal is not working properly, it’s time to call in professionals.

Garbage disposal problems sometimes require a professional diagnosis and repair approach. A DIY garbage disposal fix may be sufficient for mild blockage issues. Call our Dean’s Home Services experts to schedule garbage disposal repair in the Minneapolis area.

Step-by-Step Guide to Fixing a Blocked Garbage Disposal

Outside of mechanical problems, one of the most common issues with garbage disposals is blockages. Thankfully, removing a garbage disposal blockage is not overly difficult.

1. Cut Off the Power

Always turn off the power to your garbage disposal first. You can unplug it at the sink or switch off the circuit breaker. Never attempt to dislodge a clog while a garbage disposal is powered on.

2. Inspect the Drain Opening

Use a flashlight to investigate the drain for blockages. You could see food scraps, utensils, or fibrous waste like celery stuck in the blades.

3. Turn the Blades Manually

You can use a hex wrench to manually rotate the blades from the bottom of the garbage disposal. Doing so can get the blades moving again and dislodge the clogs. Some garbage disposals come with an attached hex wrench.

4. Use Pliers or Tongs

Never stick your hand into a garbage disposal. Turn off the power and use pliers or tongs to remove any stuck debris to clear the blades. You must be careful when unclogging a garbage disposal.

5. Clean the P-Trap

Place a bucket under your sink and remove the P-trap. Food waste that settles in this U-shaped pipe section can cause odors or clogs. Clean it thoroughly and reattach it. Often, this will fix a clogged garbage disposal.

6. Press the Reset Button

After clearing the blockage, press the reset button. Knowing how to reset a garbage disposal can sometimes help you avoid service calls. The reset button is located at the bottom of the garbage disposal. After pushing the button, restore power and test the garbage disposal’s function.

Preventing garbage disposal clogs begins with understanding how your garbage disposal works and what it can process. Read your manufacturer’s guidelines to ensure you use the unit properly.
