We aren't Electrolux, we are FixYa dot com, and you appear to have fixed it.
Resetting the board would simply involve cutting the power to it. Induction cooktops are a relatively new innovation to the home markets are in general, all Induction cooktops fail due to failing electrical components. I have a 50 year career in catering, and 10 years with induction units. Even the catering quality units with a single hob that cost $1,800 fail in 18 months to 2 years.
Contact Electrolux direct and ask if they can find the failed component and repair the board.

The breaker can still be the problem. The way to prove it is to measure the voltage at the wall plug where the cook top is plugged into the wall. Unplug the cook top and look at the pattern the plug contacts make. Should look something like a Y. Using a volt meter set on AC and 240 volts put one lead in the bottom leg of the Y and the other lead on one of the other leg contact. You should read 120 volts on each leg. If one leg has no voltage, replace the breaker in the panel. If the voltage is present on both legs of the plug then the breaker is good and the problem lies in the electronics of the cook top or perhaps a burned out heating element.
Unplug the range then you need to take the side panel off and there will be a slide out tray with the lower element in it. Disconnect the old element and reinstall the new unit in reverse order. Hope this helps
Call Electrolux or go to their web site and explain the problem there tech department will be able to tell you if you need a service call or can fix yourself.
No it is not normal, I do however assume that you removed all protective covers before use. You will need to contact the supplier of unit or elecrolux for replacement / repair under warrenty.
