I have an england pellet stove , model # 25-pdv (I think this is it cause there are 2 more 3's on there, but this is the first) and I have this same problem in a major way. It actually causes the stove to shut off ever couple of hours. At first it wasn't staying lit at all, it would shut off after the blower kicked in on start up, so we had someone come look at it, which, as I am sure you all know it is close to impossible to find someone to actually fix these things, and there was an issue with the "low fuel feed" preset so he adjusted that down to "1" and it stayed lit for about an hour while he was here. Thinking the problem was fixed we adjusted the setting to what we wanted and left it alone. It is in my basement so I don't know what is going on unless I go down there, so when I went to check on it later that night it was off again. I did not want to call the repair guy to come back since he is about 25 miles away and charged us a pretty penny to come here the first time, so spent a few days of tinkering with the 3 preset buttons on the bottom of the control panel with no luck. One night I was trying to get it lit after an unwanted shutdown and noticed it was not feeding pellets to the burn pot at all during start-up. I check a few things and could not figure out why it would just stop feeding like that, so I emptied the hopper completely to make sure the top auger was still turning. As soon as I started scooping pellets out of the hopper and they shifted around a bit, it started feeding again. I continued to empty to hopper and let the pellets that were already in the top auger feed through till the whole system was empty, filled the hopper back up and everything was fine. It was feeding pellets to the burn pot no problem, so I made the guess that the problem is that the pellets are just getting kinda stuck in the hopper and not falling down into the top auger. To test this theory, when I was home one day I went down there every hour or so, opened the hopper and pushed the pellets down and moved them around a bit, and what do you know, it didn't shut off once. Now if I had the time, or felt like walking down my basement steps every couple hours, I guess this would be fine, but I don't. Besides, even though I rent here and didn't pay for this thing, I am sure my landlord didn't shell out all that cash so someone could go and play with the pellets every so often.
I read on this post about wax paper and graphite but, I am not sure that is really the issue here. i don't think that it is that the pellets are not sliding down, I think that maybe what is happening is that the auger is sort of boring out a small cavity at the bottom of the pile and the tension of the pellets above are holding themselves up (not one good analogy comes to mind) and making a small pocket of space/air underneath the pile. I thought about taking something heavy, that would be big enough not to get caught in the auger and placing it on top of the pile of pellets. I feel like this would be just enough weight to keep things moving into the auger and not getting held up, but in the manual it says not to operate the unit with the hopper door open. I have had the door open for shot periods of time to push the pellets down but wasn't sure if it was safe to have it open for longer.
Can anyone help? I mean, this thing doesn't do such a great job at heating this place to begin with, but when it is turning off all the time it really does nothing. Is there anyone who has heard of a hopper feed problem this bad, and if so do you have any suggestions? Is it safe to leave the hopper door open for long periods of time? I realize you run the risk of foreign object falling in there, but I can't imagine that would happen in my basement. My concern is if there is any fire dangers caused by leaving the door open unattended.
If you have any answers I would appreciate them.
thanks.
