Turn off the switch, unplug it, clear any debris inside the disposal, and rinse with warm water. Many times there is something stuck in the blades that they can't handle (citrus peels, meats, stringy vegetables, etc.). You may need to turn the blades manually to find a lodged object, and it may even be under the blade. Find the reset button (usually red) and hold it for 1 minute. Plug it in, try again. Some newer models do not have the reset button, there is an opening on the bottom of the disposal to insert an allen wrench. If not, look up your model by manufacturer or Google for further instructions.
I hope this helps someone and encourages others to get the product. I think it is a great product and many of the poor reviews are because people didn't know how to use the mounting system. I gave it 4 stars because it doesn't have any tips in trouble shooting for when it leaks out the bottom. It should at least say to look at the drain hose and that it may be leaking inside from there and only appear to be leaking from the bottom. I also think Waste King should have made a video to show the EZ mount system. I mean it took me less than 10min. to do it all. Lastly, I don't like the click it can make when it turns on. While lots of people mention this and the directions say it's normal it is not "standard" in the garbage disposal business, meaning most don't make this noise. It can be startling and sound like something metal is in your disposal. While it is normal for their units, I still don't like it. It will take getting used to and then what if something metal is in my disposal will I think there isn't and that it's the click. That could cause damage very quickly if I think it's nothing and it is something.
Warranty - The average industry warranty on a garbage disposal is one year; however, it is not uncommon to see manufacturers’ warranties that can extend up to ten years. As a general rule of thumb, the more comprehensive and longer a warranty is, the more confidence the manufacturer has in the product they have made, but this is not always the case, so it is still important to do your homework.
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.
Plug the disposal and fill up the sink with hot water and detergent. Unplug and run the disposal. The spinning disk forces the water down the drain like a pump. This should clear the disposal and the drain line. If not, you'll need to inspect the plumbing. Old pipes made of iron clog easily due to internal corrosion and should be replaced with copper.
Here are some problems that every garbage disposal can run into, old or new. Learning about your garbage disposal and how it works (and how it doesn’t work, of course!) is the first step to decide if it simply needs a repair or if it needs to be replaced all together. One thing that stands for any and all situations: never stick your hands down the drain!
