Christopher75 Sorry for the delay but I have just seen this. The possibility of restoring to factory setting only occurs on the way into advanced, not on the way out. I did restore by mistake! However, I printed off the relevant pages of the Sway. A friend turned the machine on for safety whilst I held the buttons in. Once you have done it you will realise that if you do make a mistake it takes 2 minutes to rectify and is not a problem.
With regards steam preinfusion, from the little bit I can remember it is part of the standard button 1 or 2 shot but you can adjust in the advanced any part of the process.
