If the KHD pH probe calibration fails immediately, check if the KHD is enabled at the KHD settings and the PAB connection is correct.
Please try the diagnosis functions (internal pump and valve). If you can't hear anything from the KHD when activating them, there is a problem with the PAB assignment or connection.
