I tried f01 parameter from 145 to 180 - did not see any difference. I have this parameter on 150.
Today it fired up and was working untill stabilisation mode and suddenly there was a spark in ignition tube and it blows out fuse at the main switch.
I also tried igniter FKK PSX-2, it was igniting pellets only every second time, but it didn't blow out the fuse.
