Like a few others, I have been facing a P0 error from time to time. Have gone through a long support thread with Aillio but there have been no clear answers or solutions. I was roasting two 1 KG lots of naturals back to back last evening. There was quite a bit of chaff to contend with. At the end of the 2nd roast (third overall), I got a P0 error. It got me thinking whether the P0 was being initiated as a result of poor airflow due to the 1KG load and the excessive chaff being produced by the naturals.
Has anyone had airflow issues roasting naturals in the past?
