    Hello, I have a problem with my 1994 sm74. The machine stops under pressure and group 3 error appears. I have also replaced the micron that works on the pulley, but I see the pulley moving in a strange way.

    Hello, message 3 appears on the display. I checked it is not the bars, it looks like the phase micron where the belt is
