I have a 2004 englander pvd25 that I bought used last year. Had the same issue last year where the burn pot would fill up and pellets were not completely burning threw. I had the same issue this year, cleaned it out, spoke to englander and was told to switch out the gaskets which I did yesterday. I also did the leaf blower trick but the door closed during the process and now the stove will only start up for 10 seconds and I get an E1 code. I may have ruptured the vacuum switch by the door closing. A) how can you tell which one is bad & B) can I only order them online? Please help!
