I've been having sluggish performance for over a year and have struggled with the 6 blink status on my P35i whenever I ran the fan anywhere above low. I was cleaning the entire unit front and back each week with only a slight performance boost. I noticed the front gasket on the hopper lid was pushed into the unit but didn't think much of it until I stumbled upon this exchange. Thank you Mike49024 for the advice. I temporarily replaced the front gasket with a homemade gasket I cut from a hot water pipe insulating sleeve. I haven't seen a flame so big since I bought it two years ago. Ahhh. I'm finally warm in my office!
