Hello Everyone, I have a problem with my stove and I can't figure it out. I keep getting a 6 blink error but do not have or experiencing smoke inside the hopper. I have changed the esp probe and the piping from 3" to 4" right from the stove straight out 60" with a 45' on the end still same problem. Had the tech hook up his ddr to the unit and said everything looks good. This stove gets cleaned top to bottom in and out so I know my cleaning job with the stove is not the problem. Can anyone recommend anything to fix or replace.
