    Hi sir;

    error code 7DFF;

    *Check:
    During the brake test machine rotates more than 4 degrees . Check brake and belt or can be full of oil .

    ERROR code 5bfc

    *Check:
    Engine temperature > 140 degrees C ( warning ) .
    *Check:
    Engine speed exceeds allowable range .
    Wrong direction of rotation of motor found .

    About IC burn , 1) check power supply for supply the electronic board 2) Look for Dry +colder joint solder in the board
    3) cleaned all Edge connector boards!!!!!!
