My Englander 25pdvc keeps going out and then over flowing with pellets. When I say over flowing I mean over flowing, picture the entire burnpot full of unburned pellets and a large pile of pellets in the ash bin. Its happened twice now, each time while I'm not home so I cant tell you whats happening. I did call Englander today and they went over the factory settings and had me do some adjustments, I'm at 5,4,1.....I have the burn rate set to 1 and the blower on 5. The tech seemed to be stumped as to what could be happening, the only thing he could think of is maybe its the pellets. I dont know what to do, it ran the entire day no problems at all the house was a nice 77 all day, I cleaned the ashes out and refilled the hopper before going to work, when I left there was a nice flame and tons of heat pouring out. My wife called me saying the fire is out and she can see a huge pile of pellets again. There are no error codes showing on the display. Any ideas???????????????
