Your frustration starts to get ahead of you. If you are not happy just quit and dont make a show. Yes, tell us your dissapointments and experience but dont throw tomatoes every 2nd post.
I’m gonna laught hard when you gonna push start on the decent but the machine throws an error message on the tablet and wont start the shot or when you gonna pull but the machine wont stop at desired output cause the scale was disconnected. Espresso is learning, adjusting, observing and improving. If you dont want to be bothered then dont get super machines, get a pump machine with on/off switch, or a bullet proof machine with little components like for eg strietman.
And to give you a realistic perspective on stuff, I can search complains on users who got new machines from La Marzocco, Victoria Arduino, Lelit etc.
Dont take this as offensive, I dont claim that your machine was problem free, I would just gather it up, make 1 or 2 posts about it and call it closed. For every post you make the 2nd one is somehow a frustration post, let us be a tiny bit more mature. This stuff can happen even when you buy an expensive object, like a 50k $ car.
