Is it bad to run the garbage disposal without the water running?

Some say this will damage the garbage disposal, but i dont see why that is the case. Isn't a garbage disposal mechanism similar to that of a blender? Running water is beneficial if food is being thrown down the drain, but Im asking about this with no food involved.

Newer Garbage disposals all have permenantly lubricated bearings so I don't see why running them without water would hurt them. Also theoretically there should be more load on the motor with running water than with nothing in the disposal.

Unless the motor is prone to overheating (it's probably not), then there shouldn't be anything wrong with running it without any water. However, running it continuously for a while could heat the motor and put unnecessary wear-and-tear on the motor.

It is not harmful to operate an empty garbage disposal for short periods of time. In theory, if you left it on for hours, the motor could overheat and be damaged or ruined. The water does have a slight cooling effect as well as acting to flush out food particles.

I have heard that it is bad to run the garbage disposal without the water running because it is functioned by a motor which needs to be cooled off in the process of working hard.

Even if you have no food in your disposal, there could be residual pieces of food left in there or on the blades that could cause damage to the blades or clog the drain. It is best to run cold water through your disposal when turned on.

Blades? You obviously have no clue how a disposer works. There are two centrifugal weights that force the chunks through a screen that cuts the pieces up to be flushed away. There are no "blades" at all.  add a comment

It is fine to run the garbage disposal without the water running. The older models required the water to be on to help lubricate the grinding mechanism in the garbage disposal and clear away the debris. Newer models are designed to be more efficient and do not need the water at all.
