Selmi help please

If anyone out there has a lot of Selmi know how, please help. End of day today my Top decided to call it quits. The machine was accidentally taken out of temper, and less than a min later the temper button was pressed again. A few seconds later it decided to die. And Die it did. The black/red switch on the right that is usually used to restart these things is permanently stuck on red and the black seems disabled. ( not even a clicking feel when pressed)

Any thought anyone?

Thanks

did you check your power source breaker? sometimes if you are running on 3 phase but everything else is running-lights etc you can forget to check the breaker.

Thank you.

I actually went back to the shop shortly after posting and did just that. Turned out to be a blown fuse on the electrical board. ( as you said)
