What is wrong with this dryer wiring?

I recently went to move my dryer around and it hit the washing machine. When that happened the dryer basically tack welded the two machines together. After opening everything up I am confused as to what’s going on here. The outlet in the wall has the white wire going to where I would typically know the ground or neutral wire to go on a 3 prong dryer outlet. However the bottom prong is labeled on the box itself as a white/blanc. Inside the machine it’s self is wired how I know dryers to typically be wired. Also you can see the electrical tape on the right is melted. What is wrong here ??
