Good morning everyone, I have a 1.5 year old PP130 which recently started to fill the fire pot with ash quickly and leaves many partially burnt pellets. If these are still hot when the blower exhaust turns off it will smoke the room. Still running the same batch of pellets. Seems like it’s not getting enough air but strange that it just started happening and is steadily getting worse. I’m not able to get 24 hours without cleaning. Thanks in advance.
