Good day, when I connect the C3 to the power supply, the Mode switch lights up blue as it should. If I want to switch the mode, nothing happens. Only the Mode switch keeps lighting up. What is the reason for this?

I turn on the charger as indicated... The blue light turns on... But when I turn it on, it sets itself at 6 v... And I need it to charge a 12 v battery and I cannot change it to that position.

What could be possible to see if I accidentally reversed the cables on the car battery when connecting my Bosch C3 battery charger that I have been using for a few years and has now suddenly stopped working, with only the central blue light turning on and not the ones for selecting the charges?

My Bosch C3 battery charger that I've been using for some years has stopped working. The central blue light turns on, but not the ones that indicate the charging options. Maybe I absentmindedly switched the cables when connecting it to the car battery. What can I check?

Is the Bosch C3 charger malfunctioning if it selects the 2nd (motorcycle) function after a few seconds of thinking, even though it is connected to a car battery? Pressing the MODE button has no effect.

I have removed the Optima AGM Battery (4/18), 12V 55Ah from my caravan and connected it to the C3 charger. Only the blue light is displayed, indicating it is ready for use. Apparently, the battery is not being recognized. I don't have any way to enter a mode. Where could the problem lie?
