Hi McRoberts,

Thank you for contacting InSinkErator.

I do apologize for the inconvenience that you encountered with your disposer.

We understand the disposer is making an unusual noise. Unknowingly, something might have gotten down inside the disposer causing this. If it is making a “machine gun” consistent type noise, something may be caught in the protrusions of the stationary shredder ring. If it is making a “bouncing around” type sound, there may be something that is being thrown around the inside of the chamber. We recommend that you check for this using the following procedure.

1. Make sure the disposer is electrically off.
2. Hold the black baffle back, and look down into the chamber from the sink hole opening with a flashlight.
3. Do NOT put your hands inside the disposer.
4. Push the black flaps down. Shine a flashlight into the chamber to see if you can see anything that should not be there. Closely inspect the entire floor of the chamber and pay special attention to the area around the outer edge of the disposer's shredding disk. There is a small space between the "floor" (flat surface of the shredder disc) and the wall of the disposer. Just up from this space is the stationary shredder ring (it lines the entire wall of the canister) which has some small v-shaped protrusions. Follow the circumference of this ring, looking at the v-shaped protrusions, to see if you can locate anything that should not be there. Objects or food debris (such as a bone shard) may be lodged in one of these v-shaped protrusions. This will not impede the movement of the plate, but will cause a loud consistent (machine-gun type) noise as the lugs swing by and hit it.
5. If you do locate something, use a tool such as a long tongs or pliers to retrieve it. Again, do not place your hands inside the disposer.
6. Turn the faucet on and let the water run through for 15-20 seconds.
7. Switch the disposer on and check if it is operating correctly.

If the unusual noise is an “inconsistent” metallic bouncing around or scraping sound, the rotor shredder plate may be loose from the rotor shaft. You may also try the following steps:

1. Make sure the disposer is electrically OFF.
2. Obtain a flashlight and a long-handled wooden spoon or other similar tool.
3. Do NOT put your hands inside the disposer.
4. Push the black flaps down and look down into the chamber from the sink hole opening with a flashlight.
5. Shine the flashlight into the chamber. Using the end of the wooden spoon or tool, press on the top of the flat plate (floor of the chamber). It should be firm and not rock up and down like a see-saw. If it does rock up and down, your disposer will require service.

In case these steps won’t resolve the issue, kindly send me an email through insinkeratorfeedback@emerson.com with your complete contact information and serial number of your disposer and I will get in touch with you. You may also call InSinkErator AnswerLine at 1 (800) 558-5700.
