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.
STEP 7 – You may have stubborn object stuck in the blades that is preventing the motor from rotating. This means it is time to apply a little muscle. Get your handy allen wrench out and insert the tip of the short end into the hexagon shaped hole at the bottom center of the disposal. If it doesn’t fit, find or buy one that does. They usually come in multi-pack sets with various sizes to choose form. Your disposal might have had one packaged with it. if so, find it and use that one. Once inserted, rotate it a half-turn clockwise and then a half-turn counter clockwise to see if the mechanism inside the disposal will move at all. If so, it will help to move the blades back and forth a few times to force through the obstruction. After you’re done, restore power to the disposal and turn it on. At this point, your efforts may have helped your disposal to work again. If not, try one more time.
3/4th Horsepower – This garbage disposal model is ideal for households of 4-5 people. It is the model that you will most commonly find in modern day homes. These models are often equipped with more sound dampening features, which reduce the level of noise the unit produces when compared to its lower end cousins. Again, it is recommended that you look for a model with stainless steel grinding components.

Rotate the disposer to align the disposer with the drain or the discharge tube, slide the flange over drain pipe or discharge tube and insert the gasket into the discharge outlet. Then screw in the bolts that secure the flange to the disposer. Reconnect all the plumbing connections as well as the dishwasher inlet hose. Then turn the power back on at the electrical supply panel and test the unit for leaks, making sure to run cold water while the unit is running.
If the leak occurred under the sink and at the top of the disposal before you unplugged the sink drain, your leak is in the sink flange. This indicates that an improper seal exists between the unit and the sink, which can occur from corrosion or the disposal being bumped hard and out of place. This fix requires you to move the disposal altogether. Then apply a generous amount of plumber’s putty to the flange. Finally, replace the disposal and retighten the flange.

Since the mid-1990s, the Camorra has taken over the handling of refuse disposal in the region of Campania, with disastrous results for the environment and the health of the general population. Heavy metals, industrial waste, chemicals and household garbage are frequently mixed together, then dumped near roads and burnt to avoid detection, leading to severe soil and air pollution.

At one point, I did have a leak that I eventually determined was due to improper installation. (This was by the same "professional" plumber who reversed the hot and cold supply lines when installing a kitchen faucet. He just didn't connect the drain hose properly.) While investigating the issue, I called Waste King to inquire about possible in-home service or warranty replacement. I was blown away by their level of customer service: no waiting on hold, just an immediate connection to a person who really knew the product and was unexpectedly diligent in resolving my problem -- which, as it turns out, wasn't even their fault.

If you misplaced your wrench that came with the unit, don’t worry. The store you got your unit from should have replacements for as little as $3 to $5. An Allen wrench will usually work well, too. Replacing the motor is the most costly repair for a disposal, so replacing the unit may be your best bet. If the disposal is jammed and won’t budge after using your wrench, turn it off and call us right away.


You should first find out whether only the disposal is broken, or if the power has gone out completely in the areas near your kitchen sink. Try resetting the circuit breaker that leads to the kitchen, or replacing a fuse if you have an older electrical box. If the garbage disposal makes no noises at all when you flip the switch, you might also want to check under the sink to see that it’s plugged in.
