In most cases if your garbage disposal is humming it is because a foreign object is stuck in the disposal. If an item has been jammed in the blades of the disposal they will be unable to rotate. This can result in a humming noise. If this is the case simply unplug the disposal under the sink then survey the drain hole. If you discover that an object is stuck in the blades remove it. Once you have done this you can plug the disposal back in and flip the switch. This should clear up the problem.
If the disposal’s still leaking, loosen the mounting bolts and push the sink flange up until it’s slightly higher than the surface of the sink. Apply fresh plumber’s putty to the threshold between the flange and the sink. When you’ve applied enough, re-attach the unit by putting the bolts back and tightening. Wipe away excess putty that squeezed out. Finish re-installing by replacing the disposal unit on the mount. Turn the disposal back on and look for leaks.
If you have a broken seal on the inside of your garbage disposal, you will see leaking coming from the bottom of your unit. Leaks that come from the bottom of your garbage disposal are usually attributed to cracks on the inside of the device. This is due to basic wear and tear overtime. To fix this issue, you’ll need simply invest in a new garbage disposal.
If your garbage disposal is making a clicking or rattling sound, there may be some food particles that will not grind up inside. Remove power from disposer, reach into the sink hole with a pair of tongs and remove anything that is still down in the disposer. Test your disposer to be sure the noise is gone. If not continue troubleshooting your disposer issue (see below).
