I'm having issues with unburnt pellets in the bowl. It's been clogging up lately and not giving the heat it should. No fault lights. This is between the auger end and the front. Cleaned it out 3 days ago and has been running okay, but I checked this morning and found unburnt pellets in the pile on ashes. Am I losing my mind or is this normal? Also it's pushing burnt pellets over the pile of unburnt to the front of the pot and finishing combustion there.
