Hello, sorry, if the language is not good (google translate), since I can not speak German, only English.
I have a machine that I bought for parts that had a blown component (LNK364GN 7 pins).After replacing the component, each function started to work.So the pump has to be replaced.With the exception of the coffee grinder, everything works on the coffee square is switched on.I tested the grinder with mains voltage and it works.So the TEST MODE screen is closed again and nothing happens with an option.If the TEST MODE works this way or if it is selected, the user is prompted with a new message.Maybe there is someone who knows electronics to identify the problem with the motherboard.Maybe relay or transistor blown?
