Fishlover, what you do is to siphon out maybe a third of the water and set up a bucket with replacement water to put back in. You do not remove everything and scrub it because you want bacteria to get established that will help your betta survive by converting the ammonia that he will naturally produce. Once the replacement water has been treated with dechlorinator you put it into the tank.
In you current situation, I would open any access panels and get everything thoroughly dried out before trying to plug the unit back in. As others have said, it would be safest to use a ground fault interrupter when you do that so that if something isn't right, it won't electrocute you.
