This is a very interesting and instructive question for the List.
Firstly, I dont know a thing about this model.
However, you may be interested to know that from my past experience of this kind of thing with earlier model automatic machines, it is possibe that with your resetting a microswitch/es that sets the stop position, you may then end up with a bigger bill for the repair because when the actual cause of the problem is diagnosed and rectified, the brew unit may stop at some other position (due to your resetting it).
Ergo the time spent in the rectification may well be extended due to having to set the microswitch back to the position it was at originally, which could well be a trial and error thing.
Whilst you could be lucky and I could be on the wrong track, these are the kinds of things you need to think about before rolling your sleeves up, and my best advice is to take it to an authorised Saeco repairer in your area for rectification.
