Garbage disposal dead: no hum, no power

Work from the simplest cause: the motor overload (red reset), then the breaker and outlet, then the switch type (wall switch, air switch, batch-feed stopper switch). Replace the disposal only after power is proven at the outlet and the reset does nothing.

Garbage disposal hums but won't turn (jammed)

A humming disposal almost always has a jammed turntable: a hard object or packed waste is stopping the motor. Free the plate with the hex wrench from below (or a wrench on the impellers from above), clear the debris, then reset the overload. Never put a hand in the grinding chamber.

Garbage disposal leaking: top, middle or bottom

Find the exact leak point with the paper-towel test. Top = sink flange seal or mounting; middle = dishwasher inlet or discharge elbow; bottom = water inside the housing. Flange and connection leaks are fixable; water from the motor housing itself usually means internal seal failure and replacement.

Sink with disposal drains slowly or backs up

If the disposal spins and the water swirls but will not go down, the blockage is in the trap or drain line, not the disposal. Clean the baffle and chamber, plunge carefully, then open the trap. Do not use chemical drain cleaners in a disposal.
