Taken from a dishwasher (SGS45E08GB/45 FD8406) 😯

I’ve never come across such a burn up on a Bosch module before and was wondering if anyone else has come across similar?
It’s hard to put a finger on the cause but the majority of burn seems to emulate from the centre relay perhaps? It’s then burnt through the ribbon cable and fused the microprocessor?
In any event I’m not at all sure if a component within the machine had caused it. Usually isolated areas of PCB damage can be traced to external component failure but sadly I fear not in this case. 🙁
