Yes, quite a remarkeable burn spot, also on the back cover! I assume it must have been a strong 'spark' during the 'explosion'. I was not there when it happened, it is my daughters cooking plate. I think they heared 'a  noise' and the corresponding  fuse blew.
In the mean time it was decided to replace the cooking top by a larger one as the current has the problem of not enough room for several big size cooking pots. I wil (some day...) grind away the material around the burned fuses and see what's underneath. May be I can solder some wires as new 'fuses' (?- what value?) and of course replace the defective IGBT's and rectifier, and also check the capacitors...
Anyhow, thanks for the reactions!

Hi everyone. Thank you so much for your insights and guidance.
I managed to fix a Siemens EX877LYC1E using the approach described. I had many touch buttons that had falled out over time and I got them all working again by soldering a copper wire to either the resistor or the spot on the back that has connection to it (measured using multimeter) and attaching in to the top of the corresponding button. Worked like a charm.
