I have a La Scala at home, and it hurts my brain to think about this machine in an office environment. What will happen with it after you have gone? Perhaps a mercy killing is in place...

It is a fine piece of equipment. I have installed the Erics Therm. and it shows that the machine needs quite a long flush, like 8 seconds after waterdance (250-300 cl?) but of course YMMV (my pressostat is at 1.0-1.2). It has all the autofil and shut off etc., so you don't have to worry about that. For the rest: it's just a 2 liter HX, so what's there to tell?

If you have any questions left don't hesitate to ask. But I reckon you have worked it out already.
Couldn't you swap the Butterfly for a superauto, when you will be going...?

Hey there, glad to see another Butterfly user! Interesting about your flush length. I only flush for about 2 seconds after the dance and our p-stat is between 1.1-1.4 I think. I will confirm that in a minute when I make my morning shot. I usually rebound for 30-45 seconds. Are you listening for water dance with portafilter on or off? Here's what I do... I put the pf gently in the grouphead and flush for 3 seconds and then let it sit for another few seconds to get the pf warmed up. I then remove the pf and continue the grouphead flush + 2 seceonds. During the rebound I'm wiping the pf dry, dosing, tamping, etc.

I'm here for another 6 weeks probably. I think I may have a demo session and also write up a detailed user guide.

With the Erics thermometer I no longer pay attention to the waterdance, I just look at the temperature read out . But before I installed the Erics I would look at the water coming out from the pf. I didn't listen, partly because the machine is too loud, but also because visual signs would seem enough for me: the water boils, then flows "uneasy", then comes to rest. That is when I would start to count a few seconds and stop. But after the installation of the Erics, my flush has become somewhat longer. I now see it needs a few seconds longer to cool it down to 90 C (after the rebound you get, like, 94C). I have to say that just a few weeks before the Erics, I retrofitted a flowrestrictor, and these two together were a big change.

I normally do a flush with pf in place, then 30-40 sec. rebound.
