In Sink Erator model 777ss
Purchased 9/10/2001

Unit seems to process food waste OK but it makes a very loud grinding noise. It sounds to me like metal-to-metal contact. This noise is intermittent but occurs probably 90% of the time. I cannot feel any foreign material of any type inside the unit.

I found some teeth when I put my hand down into it

Can I change the teeth in this model?

Either there is something stuck in there or perhaps the bearings that support the central spindle have had enough, causing the grinding wheel to contact the body of the unit. At 9 years old though, its done quite well.....!
