I recently replaced the group head seal on a customers Ascaso Duo machine, so while I had the opportunity I checked the brew water temp at the group head. I was pretty surprised by what I found.
I used a Scace device & all measurements were logged after a 2 sec purge.

Graph 2: Temp guage drops from "blue" zone into "black" zone

How would a home user without a Scace device ever find the right temp on one of these machines if they all behave the way this one does??
