Chattering Garbage Disposal

Our ISS Insinkerator garbage disposal suddenly began making load metal banging sound; motor turns with crank; there is nothing alien inside the drain.

What coukd be the cause. Any suggestions before I start taking it all apart?

You may not see anything on top of the wheel, but sometimes something can get lodged just underneath... But the chatter is also commonly caused by a "tooth" beginning to come loose... If it is more than 5 or 6 years old, I would just replace it rather than take it apart... It isn't worth the effort of working on it... If you get another one, the ISS Insinkerator is a great dependable unit... (assuming it is not the victim of abuse)...

Thanks Ragnar for your advice. Unit seems fairly new (came with recently purchased house, but without documentation).

I will have to dismantle unit to get better look. There appear to be two hammers that rotate inside the catch bassin. I do not see a "wheel". I suspect the top nut may have come off the shaft and is rattling inside when the hammers rotate.

Thanks for your support.
