Hello all- I had been a participating member here some time ago, bought my S1 from Chris @ Chris' Coffee. Great service btw. For some reason my posts and account are gone from this site. Oh well, I signed up again :D.
My machine is an original S1, it has been working great. I sent it in once last year to the listed "authorized" repair center here in Los angeles, for a boiler cleaning and adjustment of the group temp / pump pressure. La Spaziale USA referred me to the authorized center.
Basically, the issues I was having are as follows:
1. group boiler would not get up to my desired temp, even at max setting- all my shots are pulling at 180 degrees max, can't get temps over that.
2. steam plastic tube from boiler to wand needed replacing, it was crusty and feeling brittle
3. steam boiler kept over-pressuring and popping the safety valve (it would get up to almost 2 bar, then "pop".
So I asked the repair center to do a thorough cleaning of the boilers, replace any temp probes etc as needed, and then make sure everything tests out to factory specs on temps and pump pressure. I use this machine every day religiously (I'm sipping a double latte as I type this.. :D).
Well, needless to say they were total MONKEYS
. I got my S1 back after two weeks, fired it up, and the nut that holds the steam tube to the wand was loose- very loose and it was hissing! It could have blown off and burned someone in the face. Also, the hot water solenoid control valve was loose, panels not put back on right, and there was no difference in group temp than before- obviously all they did was a minor cleaning of the boilers (probably by flushing cleaner through them), and they replaced the steam tube and steam boiler probe. They did not test or adjust anything. I had to demand my money back, it was not a good situation.
So, I still have the issue of my group temp not getting hot enough with the shot water. I am using an espresso that calls for a 203 degree pull, but I cannot get the shot water any hotter than 180, even with the temp up to 120 on the S1 aand fine adjustment at max. Heck the steam boiler water is coming out at about 198 degrees.
Any ideas guys on what needs to be fixed- or is 180 degree shot water the hottest it gets? I can do the work myself- I was really busy at the time and hoped that sending my S1 to a proper repair center would be faster and worth the few hundred spent- - big mistake! BTW I reported that place to LaSpaziale.
Oh and I have invested in a better water filtration system, commercial grade designed for espresso machines, to ensure no future scale build up. The other system I had was ok but still allowing scale to build over time.
