Did you get water in under the burners? Unplug the unit if it is still.
If the water is what blew the curcit it may have damaged one of the switches. With the unit unplugged remove the knobs. Use a hair dryer on low and dry the switches under where the knobs were. This can take quit a wial. You can leave it unplugged over night it you need to. Also you can still use the cook top with the power off.

Post me back later or in the morning and let me know if drying worked.
