Query: First use = GREAT! Second use = Blew a fuse!

First time I used this pressure washer it was wonderful and easy to use. I cleaned my entire house. But my finger was numb for one month afterwards!Second time I used this pressure washer, I turned it on and it immediately blew a fuse and now it doesn't work anymore! Must get fixed!
