    The home position is not detected when the sensor is moved up/down (i.e., the
    sensor
    has not gone off).


    Disconnect and then connect J508, J552, and J553 of the DC
    controller PCB. Disconnect
    and then connect J4001 and J4002 of the fixing inlet sensor
    ascent/descent motor driver
    PCB; as necessary, replace the fixing inlet sensor ascent/
    descent motor. Replace the fixing
    inlet sensor ascent/descent motor driver PCB.

    If it ain't broke, don't fix it

    how many copies has the machine ?

    In some cases the motor should be changed, even if you think it is ok.

    The Fixing Inlet Sensor/Motor Driver pcb FM2-5065-000 could also cause this error...also check your frame side connector for cracks and bent pins
    Accidents don't just happen. They must be carelessly planned.
