How can i fix my Service M31031 caress 1300 washine machine that wont fill?

Got a problem with my washing machine. When switched on, there is a click sound to say that the door is locked and after that nothing happens. No water filling, no drum rotating , etc...

Just as a note, the first time when it stopped working was when i switched on, it filled with water and stopped in the middle of filling. Thats it, no drianing also. I drained the water when i cleaned the lint filter.

Could you tell me what has gone wrong and how much will it take to repair, option 1 by a professional , option 2 by me.
