HiI have a Saeco Moltio HD8769/01, which is now almost five years old. This week the display showed the wrench with the number 15 when I started the engine, I googled it a bit and it seems to have something to do with the heating circuit. Here and in a few other forums there are already some things to do, but what I tried so far did not work. But since I can only solder a little bit and only have a superficial knowledge of electronics, maybe someone can help me here. I have already measured these two thermal fuses on the boiler and both have a passage. So they're still okay, right? Even if I unplug the plug that goes from the board to the boiler, there is only the error 15.my guess would be that the problem is somewhere on the board. On the triak I also made a continuity measurement (currentless). There is a continuity on the two outer pins, not on the middle one. Is that correct? What else can I test, or what could be the problem? Thanks a lot
