Harman p68 shutting off randomly

[Pgilz]

Hello, I have a harman p68 and it keeps shutting down randomly. I've replaced the esp probe and gave the pellet stove a good cleaning. It does make a metallic grinding noise once in a blue moon. Maybe creisote in the auger shoot? My exhaust hasn't been cleaned in a while but looks alright. Its only about 3 1/2'. Its giving me 6 flashing lights when it shuts down. Feed rate too high? Too low? Do I need to replace the k rope around the glass?

How does the flame look when running?

Have a look at these, I would check your burn pot holes to see if they’re all open and not carbon’d up as well as your air intake flapper and path to the burnpot
