A friend of my parents has an XXV, and is having feed problems. I'll do my best to describe it. She said that sometimes during the night or during the day, the stove will stop feeding pellets. Usually all it takes to fix the problem is sticking your hand in the hopper and sloshing the pellets around a little bit. It's a problem because the stove will sometimes go out during the night and they'll wake up to a cold house. It has happened with several different brands of pellets and when she contacted the dealer (who is an idiot in my opinoin, and by the opinion of many others) and he said its because she's not burning his brand of pellets. She said it occured with his brand, as well as the brand she is currently using. Ultimately it sounds like a feed motor on its way out to me, but that's just a general guess as I am not super knowledgeable when it comes to pellet stoves. Anyone care to share a similar situation, or something she can do?
