My husband took the bottom off the machine and it looked as if mice had taken up residence. We cleaned all the stuff out, but the grinding continued. He looked at the belt, and it seems very loose near the speed regulator. He tightened it up with a screwdriver underneath it and the noise stopped. He wonders if the machine needs a new belt and, if so, is it a do-it-himself job. Thanks.

Hello Sara,
With this extra information you need to check the bottom nylon gears underneath the raceway to see if some of the gear has broken away.
