What firmware version?

For tuning the hotend, try using M303 T0 S240 instead to try tuning as a tool instead of just a heater. This will use the fan to try and compensate for it's cooling effect.

@peirof When you ran this test did you also have the bed heater turned on?

@gloomyandy no...

M303 T0 S240

I have tried that gcode (M303 T0 S240), and the same error. But the Hotend fan does not turn... I thought that the fan was not working... but on the Status page, I made it turn manually... I am going to check if I have the temperature sensor configured correctly, maybe it's reading another temperature than the real one...
