Garbage Disposal Jammed? Here's What to Try Before Calling a Plumber
You flip the switch, and instead of the usual grinding sound, you get a low hum or nothing at all. A jammed garbage disposal is one of the most common kitchen headaches, and the good news is that fixing it yourself is usually quick and doesn't require any special skill. It does require following the steps in order, though, and one very important safety rule.
First, the Rule That Matters Most
Before you do anything else: never put your hand down the disposal, even with the power off, even if you can see exactly what's stuck. Disposals can have residual power or accidentally get triggered, and the blades and internal components can cause serious injury in an instant. Every fix below uses a tool, not your fingers.
Tools You'll Need
- A disposal wrench or 1/4-inch hex Allen key (many disposals include one taped to the unit or in the manual)
- A flashlight
- Tongs or pliers, for removing debris once it's freed
- Access to the breaker panel, if needed
Step 1: Turn Off the Power
Flip the wall switch off, and if you'll be doing more than a quick reset, switch off the breaker that controls the disposal too. This isn't optional.
Step 2: Look for the Manual Reset Button
Most disposals have a small red or black reset button on the underside of the unit. If the motor tripped from overheating, which often happens when it's jammed, pressing this can sometimes get things moving again once the obstruction is cleared. Don't press it yet, though, until you've freed the jam, or it may just trip again.
Step 3: Manually Free the Flywheel
Look at the bottom center of the disposal for a small hexagonal hole. This is where the disposal wrench or hex key goes. Insert it and turn it firmly back and forth. You're manually rotating the flywheel inside, which often breaks loose whatever's causing the jam, whether it's a stray bone fragment, a piece of glass, or fibrous food.
- Insert the hex key into the bottom hole
- Turn it clockwise and counterclockwise repeatedly, feeling for the point of resistance to loosen
- Once it spins freely in both directions, remove the key
Step 4: Check Inside From the Top (With the Power Still Off)
With the power still fully off, use a flashlight to look down into the disposal chamber. If you can see the obstruction, use tongs or needle-nose pliers to remove it, never your hand.
Step 5: Reset and Test
Press the reset button on the bottom of the unit, restore power at the breaker, flip the wall switch back on, and run water while testing the disposal briefly. If it spins freely and sounds normal, you're back in business.
When to Stop and Call for Help
If the flywheel won't turn even with the hex key, if the disposal trips the breaker repeatedly, or if you smell burning, that points to a motor issue rather than a simple jam, and further attempts risk making things worse or creating an electrical hazard. A disposal that hums but never spins, no matter how many times you reset it, usually needs a professional look. ProFlow Plumbing can diagnose whether it's a fixable jam, a failing motor, or time for a replacement, so you're not stuck guessing in the middle of dinner prep.
