If you have no signs of life at all, you'll need to remove the kick panel below the door and locate the 3" x 3" junction box on the front of your dishwasher below the tub. This is where the power cord from your house connects to the dishwasher itself. With a multimeter, you'd need to test to see if you're still definitely getting 120 volts between the power and neutral wire on the dishwasher. If all that checks good, then is sounds like your door latch switch shorted out in the storm because nothing else would cut all operations on the dishwasher and make it appear dead if it's getting power from your house. Below is a link to the latch switch assembly you'd need to order for your model.
