Zanussi FJ1093 Washer will not start?

Many thanks to the person that responded on how to get the seal off my washer to get at the door interlock, I have removed the door interlock and dismantled it and this visually seems to be ok so refitted it so I presume there must be another reason why the machine is not starting. As I stated previously, the mains light is on but the washer will not operate in any mode. eg drain wash or spin. The interlock switch cannot be heard to click after closing the door and choosing an operation and the door light does not come on so I am thinking there is no power going to the interlock. Is there something which the machine checks before the interlock activates, such as a pressure switch or or is there a fuse somewhere within the machine. A circuit diagram would be very helpful. ps I am a qualified electro/mech engineer (but not familiar with washers) so no need to mention the safety side. Many thanks
