90's movie with blonde girl

There's a 90's movie that had a scene where a blonde girl in her teens teases her younger brother and his friend by pretending to unbutton her white blouse. And then she goes to the kitchen...
(im not sure but i think it was the dishwasher that wasnt working properly, so water spills out onto the kitchen floor... And we see sparks/electricity coming from inside the dishwasher)..

The blonde girl is sitting on a stool and she's barefoot, it hints that the girl will probably be electrocuted but i dont remember if she actually does.
I think it was supposed to be a scary movie..
Also, i dont think the blonde girl and her brother were the main characters in the movie...

I think it's from the early or mid 90's but it could be from the late 80's
