My chaff filter doesn’t fit well into the rubber grommet anymore so it gets pulled into the fan making a terrible noise. Do I need to replace the grommet? I’d had my roaster for quite a while and it’s still the original filter and grommet.
I think that is what you will need to do.
It is available from Sweet Maria’s for $14.00

In addition to @billc’s advice, I would suggest looking at the position of the fan. At least on the R2, when you remove the fan for cleaning; it’s important to replace it with only 3mm from the edge to ensure it doesn’t hit the grommet.
Thanks. The fan is in the correct spot. I’ll get a new grommet (might as well get some green coffee to go with it 
)

For anybody else that might come across this thread and wonder what we mean by seating the chaff collector in the grommet:

I ordered a spare chaff filter basket a while ago and found the fit with the original gasket was too loose so I ended up ordering a spare gasket to pair with it to make sure it had a secure fit.
Now I alternate gasket/chaff filters so that I’m using a clean one when I’m roasting.
