The last two times I used my roaster, there was a distinct lack of chaff in the chaff chamber. The chaff coming out the front appears to be the same amount as usual. The beans are from a new shipment but are the same origin and varietal I used before.
Not sure if this is related, but both times I got the dreaded ErC 6864 error immediately upon turning on the roaster and then intermittently over the next 45 minutes or so. Once the roaster was nice and hot, the error thankfully went away. I called Sweet Maria’s to order a replacement IBTS fan. But they have failed to call back
Does anyone have any ideas or suggestions on what I should do to investigate either or both of the above problems? Thanks.
