Not turning on

This happens when you don’t hear a humming sound when you turn the switch on. It basically means that the motor is not picking the electrical current. Before you settle down on that as a problem, make sure that you are plugged in well. There are cases that you may find that the disposal was not plugged in well yet you may think that it is faulty. There are home remedies that you may try and it may work for you. If you are plugged in well and it is still not humming, try to reset the unit. You can do this by pressing the red reset button that is normally at the bottom of the unit. This will act as a circuit breaker and may make it work. If this does not revive your system, try checking the main service panel to reset the circuit breaker lever incase it has tripped. If the circuit breaker is not the problem, chances maybe it might be a wiring problem which can be addressed by checking the wiring connections and fixing any loose connections. If not, it might be a problem with the switch which will oblige you to replace it. If all those options do not work then the disposal might be the problem and will need replacement.

Disposal does not grind

In some cases, the disposal may hum but does not grind. This means that the inner flywheel has a problem. This interferes with the circuit breaker make it to trip quickly. If this goes on for a while it burns out the motor especially for the case where the circuit breaker is not working well. Most of the time this is caused by a foreign object being lodged in. The solution to this is trying to dislodge the object by turning the wrench clockwise. You will know the foreign object has dislodged when the flywheel moves quickly.


This is the most common problem with disposals and can happen on several points on a disposal mainly the sink flange and the hose. Depending on the point of leakage, it can be fixed different. If its at the sink flange check if the bolts are loose or not. On the hose you will have to makes sure that the hose clamp is tight. If it is tight and still leaking you will have to replace the hose.
