Firstly, you should see if your fuse is broken or not, you can check with a multimeter. If you can see that the fuse has broken, replace it and see if your dishwasher works then. If this doesn't work, call your repairman as it may have damaged internal components.
You should find the reciept for the dishwasher so you call the electric company to tell them the power surge ruined your dishwasher you can tell them the replacement cost.
Often after a power surge has occurred things need to be reset and many plug-ins have a red reset button that is in between the two plugs and simply pushing this can fix the problem sometimes or try to unplug the dishwasher and replug it.
first check to see if the breaker that the dishwasher is hooked up to has been tripped ifthat has happened just flip the breaker back over and it should fix the problem. If the breaker is ok then you may need a new dishwasher
