Hello, my Nespresso Essenza c101 does not turn on anymore (all lights are off) and since it's a machine I bought abroad (and quite old) the repair shop cannot find the necessary replacement part (main board) through their usual channels. They agreed to make the repair if I find the required part but I am not sure what to buy. I found the CB for seemingly identical machines with different model numbers (such as C91) but I am not sure whether they are compatible. Is there a way to find out what is the part number for the circuit board I need so that I can buy one that is compatible?
