Do Not Buy A New One Yet
A disposal that hums but does not turn is almost never dead. It is jammed, and the motor is straining against something stuck in the grind chamber. Most units have a reset button underneath and a hex socket for freeing the flywheel, and between those two the majority of humming disposals come back to life.
The local factor is the same one that shortens water heater life in this county: hard water. Scale works on the grind chamber and the seal beneath it, which is why a unit leaking from the bottom is normally past repair rather than worth a new gasket, while one leaking at the sink flange usually just needs resetting in fresh plumber's putty.
We will tell you that on the phone. If it turns out to be the fix, you did not need us, and we would rather you knew that than paid for a visit to press a button.
What does need a plumber: leaks, a unit that is silent with no response to the reset, one that trips the breaker every time, and anything that has been leaking under the sink long enough to damage the cabinet.
The first one you can often solve yourself in five minutes.
Jammed, not dead. Kill the power, free the flywheel with the hex wrench from underneath, then press the reset button. This solves it more often than not, and we will walk you through it before booking a visit.
No hum and no response usually means the reset has tripped, the switch has failed, or the motor has gone. The first two are cheap. The third is a replacement.
Sink flange, dishwasher connection or discharge pipe, in roughly that order of likelihood. Worth fixing quickly, because a slow leak destroys a sink cabinet.
Usually the drain line beyond the disposal rather than the unit itself. Grinding does not stop grease building up further down the pipe.
Often something that should not be in there, such as a bottle cap or cutlery. Sometimes worn components. Stop using it before it damages the chamber.
A unit tripping its overload repeatedly is being asked to do more than it can, or is failing. Either way it is a signal rather than a routine.
If it is humming, try the reset before you book anything.
A disposal is inexpensive enough that repair is not always the right call.
| Repair | Replace | |
|---|---|---|
| Humming and jammed | Often free advice on the phone | Replacement is unnecessary |
| Tripped reset only | Press the button | Nothing is wrong with the unit |
| Leaking at the flange | Reseal it | Replacement is overkill |
| Leaking from the body | Not repairable | The housing has failed |
| Motor dead, under 5 years | Check the warranty first | Replace if out of warranty |
| Motor dead, over 10 years | Repair rarely pays | New units are inexpensive |
| Rust in the grind chamber | Not repairable | Replace before it leaks |
We find what is actually wrong rather than replacing the first part that could explain it. The fix is often smaller than expected.
You get the price before work starts, parts included, and an honest read on repair versus replacement.
We complete the work, test it in front of you, and leave the area the way we found it.

If it is humming, try the reset first and keep your money. If it is leaking or silent, that is what we are for.
A disposal that backs up is usually the line past it, not the unit.
