The duct was good too
Okay then after trying to force the screw with its codes. He dismantled the part before the elbow just outside the silo.
There everything was fine, there were pellets.
He therefore turned this part of the screw from the console.
This allowed to re-fill the transparent pipe but even after that, the pellets did not arrive on the plate.
He therefore made another manipulation which made it possible to rotate only the part which feeds the plate.
And there, the pellets are finally going up. And bingo the ignition is gone.
He showed me all the codes that were displayed to verify that everything was fine.
He's staying two hours. It is not certain that this defusing of the screw is due to a lack of pellets. There was also dust in my pellets.
Anyway, she left, I hope that tomorrow morning she will restart without worries.
