Cooktop's electronic igniter started clicking all... (by 3 users)

I have a two year old Bosch gas cooktop (NGT73). The weird thing happened last night when the cooktop's electronic igniter started clicking all by itself. I had to turn it off via the circuit breaker and now just cook by lighting a match to the burner until I can figure this out. I know it's not the case of a GFI electrical circuit problem as stated in the previous solutions as this cooktop has been working fine for the past 2 years.

So what is causing this and is there a simple remedy?
