What is going on
Disposals jam when something hard or stringy wraps the grinding plate. The motor hums because it is trying and cannot turn. The reset button pops because the motor overheated. Leaks come from three spots: the sink flange at the top, the dishwasher or drain connection on the side, or the body itself at the bottom. That last one means the internal seals have failed. Bad smells are usually food packed under the splash guard or a partial clog in the trap beyond the unit.
What we check
- 01
Free spin
Hex key in the bottom to see if the plate turns.
- 02
Reset and power
Reset button, switch and outlet all tested.
- 03
Leak location
Top, side or bottom. The answer decides repair versus replace.
- 04
Trap and drain
A clogged trap can make a working disposal look broken.
- 05
Dishwasher line
Checked for backflow into the disposal.
Your options
Clear and reset
Jammed or tripped unit with a healthy motor.
Reseal connections
Leaks at the flange, drain elbow or dishwasher inlet.
Replace the unit
Leaking from the body, rusted out, or a motor that has quit.
Before we get there
Switch it off and leave it off. Do not reach into the chamber. Press the red reset button on the bottom of the unit once. If it hums again after a reset, stop there. Running a jammed motor is how a simple repair becomes a replacement.
