    Says the WSM but neither ratchet sound nor stop while (endless) turning the piston clockwise back.
    pls. might anyone tell me whats the issue.

    If the piston turns but doesn't wind back into the caliper then there's an internal problem, probably the pawl not stopping the ratchet from turning.

    The piston fully winds back into the caliper but neither a ratchet sound, endless clockwise winding without ratchet sound or resistance

    Does operating the handbrake quadrant manually bring the piston out again?

    No, when I turn the handbrake lever I can see the strut moving upwards pushing the wedge but neither piston movements nor ratchet sound

    The lever & pawl are probably not seated correctly. I had this issue when rebuilding my calipers a couple of weeks ago.

    Or the lever doesn't have an edge anymore and just slipping over the pawl teeth.
