yes, you must resize the photo to fit the website.
It is true about dislodging scale could get stuck in a hose and make it worse than it is now. But I would descale the machine, just not till you get more comfortable with it. If you do a bunch of stuff before you learn more about it, you can't tell what is new/different to trouble shoot it. Plindy helped me take the whole thing apart to do a real good descaling. But for a 3 year old machine I think there was not much crud in it.
It depends on the water and usage. If it works I would get comfortable with it and get a feel for what is normal then later take it apart or take the case off and open the valve and drain the boiler that way. I am not a fan of the steam wand descale because it seems too easy to get water on the electronic brain.
Buying advice: GRINDER GRINDER GRINDER. Don't cheap out on the grinder.

I will take your advise and hold off on descaling. I have read that HX machines should not be descaled. Also, if descale is done unwanted particles can wind up in the wrong place and cause harm. I heard best to have tech open machine and do descale with boiler apart. (for us newbies).
That advice was either misunderstood or came from someone making a living repairing or selling espresso machines. Depending on the quality of the water being used and the frequency of use of the machine, not descaling can lead to the demise of the heating element, overfilling of the boiler, or just poor performance in a short time. there are certain situations where descaling a HX machine is difficult or somewhat complicated.

I will take this advice. Im comfortable warming up machine and using it now. After I use machine for a couple of more weeks I would like to take cover off and open the valve on boiler to descale that way, but of course I will need detailed instructions before I attempted this. Your input has been extremely helpful to me as I know very little. My machine is 8 years old according to date stamp on bottom of machine.
