Why is my garbage disposal not working?

A garbage disposal that won't work is usually caused by a jam, electrical issue, or safety shutoff activation. The most common culprits are food blockages, tripped reset buttons, or power supply problems that can often be resolved with simple troubleshooting steps.

Start with the electrical basics - check if the disposal is getting power by ensuring the wall switch is on and the unit is plugged in securely under the sink. Look for a small red reset button on the bottom of the disposal unit and press it firmly if it's popped out. If your kitchen has GFCI outlets, check if the reset button on the outlet needs to be pressed as well.

If the unit has power but won't turn on, it's likely jammed with food debris. Turn off the power at the switch and unplug the unit for safety. Never put your hand inside the disposal. Instead, use the hex wrench (Allen key) that came with your disposal - insert it into the bottom center of the unit and turn it back and forth to manually rotate the grinding mechanism. You can also try using wooden tongs or pliers to remove visible obstructions from the top.

In Ottawa homes, garbage disposals face unique challenges during winter months when grease congeals more easily in cold pipes. Hard water common in our area can also cause mineral buildup that affects performance. If you hear humming but the unit won't turn, this typically indicates a jam rather than motor failure.

Safety is crucial - never use chemical drain cleaners in a disposal, and avoid putting fibrous foods (celery, corn husks), grease, or non-food items down the unit. If these troubleshooting steps don't resolve the issue, or if you smell burning or see water leaking, the motor may have failed or there could be an electrical problem requiring professional attention.

If your disposal needs replacement or professional repair, Ottawa Pro Plumbing can diagnose the issue and recommend whether repair or replacement makes more financial sense for your specific situation.
