If there are no signs of life at all on the appliance and nothing runs, it suggests a failure of the main control board.
(I am assuming there is power from the supply it's plugged into, if you haven't checked, plug something else into it).
You may already be aware of the warranty but I'll post this anyway, just in case.
If you have proof of purchase, you have a 2 year warranty on your appliance from Bosch.
You are supposed to register for the 2nd year warranty but I've never come across a refusal from Bosch if you have the proof of purchase.
Sorry, if power is getting to your machine and it's totally dead, it's most likely the control board.
I'd suggest checking the supply, check the wiring connection at the machine and if all is ok, get Bosch in to repair it.
Hope this helps
