Washing machine?

Hi there
I have a Hoover Vision HD 7kg front loader.We had a power surge and the machine tripped our circuit board.once the power was on and I connected the machine "the door security light is constantly flashing "ive pushed and fiddled around with the door.Pressed all buttons ,turned on and off numerous times,tried different cycles.

Its reaaly doing my head in .I would love it if anybody has had the similar problem and how they managed to fix it.Or if anyone on the worldwide web has the answer?
