    I have error code U01. It is probably something with the register control / senor. The machine does not start because it probably cannot find the position. You can't do anything. Does anyone have an idea what it can be? I'm grateful for any advice. Regards

    Hi sir;
    If you have a SM 52 with Compact Cptronic, will strongly recommend that you test the electronic board NTM, THIS is power supply the generate stabilize for the electronics circuits boards.

    Measure the Input +output in the main transformer, if the the Vca, in 10% of tolerance, in that way affecting the machine.

    1) Perform a visual inspection : look for loose and broken wires, improperly seated connectors, loose or
    broken wires
    misset switch, missing jumpers. and so on.
    Chech for obviously damaged component(components burned or discolore due to overheating);
    Dust + dirt + tear +wear

    2) Reseating Boards and components:
    Edge connectors are a common souorce of problems. Power down the system and remove the PC
    boards. Examine the edge connector
    for contamination and clean with contacts cleaner contacts. Reseat any loose components such as
    scoketed ICs) . Reseat the
    boards and power up.
