I have the Englander pellet stove, the one with the brass louvers on the sides, I believe the model is PVDC 55, something like that. Anyways, I keep getting a Error Code E1. Then I check the vacuum hose at the exhaust blower side, clamp on hose Very Hot to touch. And I use to hear vacuum Hissing once the hose is taken off that exhaust blower chamber nipple, then shuts down again after I restarted it from the E1 code. I do that just to hear if there is that vacuum Hiss for troubleshooting. But lately that Hiss is gone. Is the exhaust Blower chamber suppose to get Super Hot along with the clamp on the hose, too hot to touch? I understand heat travels through that but should your finger actually get almost burnt on that clamp from the heat? The hose does not Crack, it just seems to get so hot it somewhat deforms the ends of the hose just a tiny bit I think to cause a vacuum leak. But not too noticeable to the eye at the same time. The hose on there is that Federal Blue hose, the good stuff. Anyway I also checked the vacuum switch where the other end of the hose connects to. Took the hose off the exhaust blower end and sucked on it to listen for the clicking sound in the switch to somewhat tell if it's ok? Sound right? It clicked. Most of the time the stove will run for about 5-7 hours, then the E1 code shuts it down. That's when I check all the above all over again, and again! I clean the stove Weekly (vacuum inside all over), I even clean the flue outside once a week. The Hole inside the stove for the other vacuum switch is clear, (right side wall). In the past month I had some Nasty pellets that were all crumbly, and long in size, Brand from Lee Energy name from lee Energy Solutions (Green bag) from Menards. terrible burn as well!! Bought 5 bags, big mistake. Now using Somerset, great pellets these are! menards keeps switching brands everytime I go there! So with this said, could the Bad pellets clog up the exhaust blower chamber and channel (where exhaust motor is), causing a smaller area inside the chamber for heat to escape through flue, also causing a restriction of heat to escape because of dust build-up in there? Then giving me the E1 code because of restriction? Then in turn making the hose clamp so Hot to the touch? Sounds logical. Can anyone write back so I can figure this out with help? The stove is my primary source of heat as well. And right now it's off and using space heaters and it's 18 degrees outside right now. Thanks for any help!!
