Honestly, the espresso from this machine is pretty ordinary too. Looks nice when it pours from the spout, nice viscosity and colour, but lacks sweetness of balance. Often has a bitter finish.
One things for sure, this is going to force me to learn about the inner workings of an HX machine.
Shortly after posting this, my machine had pump or pump motor problems so its been away at the espresso mechanics for the past two weeks. Ive not had a chance to take the knowledge in this thread and apply it yet.
Frustratingly, the techs gave the boiler an acid flush and new seals even though I told them the seals were a week old and the pump was the problem, not a contaminated boiler. I wont go mentioning company names, needless to say Im a little displeased.

Ill update when theres news.
So sorry to hear... Considering it started out as wet steam ?
Sorry... Seen some service in my time that should have never been..
What is worse is when things dont work and or get damaged and you end up paying for it. In one manner or another...
Remember if your paying for it; you get to keep the dead parts... Just mike sure they are from your machine.... They often tell an interesting story..
Will be at the Hilton Tuesday night and fly out Wednesday afternoon - if ya around... Work could keep me a bit late and around the hotel.. But feel free to drop me a line or Call in.
Unfortunately after two wet weeks in a row, my events for last Saturday and today were canceled, meaning I had 12 litres of milk going off tomorrow. So, what do you do with 12 litres of milk you cant use?
Practice.
So, today I steamed my way through (almost) 12 litres of milk.
I have to say, after getting my machine back, and working on my technique Im quite happy with the results. Was the problem with me all along? I still dont think so. I could get good results on other commercial machines without much effort. Perhaps the milk I was using the other week was crap. The milk was full of tiny bubbles surface bubbles the way Ive seen on sub-par milk before. Perhaps my machine has been fine tuned while away. Not sure.
For those wondering, my machines pstat stops at 1.2 bar and kicks in again when it drops below 1 bar.
Something Im unsure of is where the adjusting the pstat widens the deadband or simply moves it up or down the pressure range?

So what did they find / say ?
As I said above, very little information from them.
One thing Ive done in the past day is downgrade it to 10 amps (in consultation with both an electrician and espresso machine tech) but I doubt that would have an effect on steam performance in a good way.

In general the deadband is fixed and a characteristic of the pstat..
Its a Sirai pressure stat btw, if that helps give an answer. So if I crank the pstat a few revolutions, its only going to move that .2 bar deadband up or down so that the top end might be 1.8 bar for example with a low end of 1.6 bar?
Not suggesting these are ideal settings, simply trying to illustrate.

Oh, do you like my giant bucketccino above?
as your adjusting the screw against a spring in the Sari i would think its going to have some effect on the dead band but I have no real idea how much (not much I reckon as the movement seems small on the screw / spring). as AM said (yes and no) as your also changing other dynamics of the machine.
you would have a bigger effect on dead band (time wise) by insulating the boiler
but i assume your really talking how much "bar" in the deadband not the time frame of it.
Designed to adjust from .5 bar to 1.5 bar. These switches are a VERY common replacement item on most brands of espresso machine.
This is the most probable fix if your espresso machine has any of the following symptoms:
• Looses pressure randomly throughout the day
• Does not stop heating or machine over pressures by spraying out the top
• Has a large swing from low operating pressure to high
What is low to high..
Looking fo the full tec specs as that should provide all the linearity and response curves and then your informed...
