The thermosyphon/HX part of the machine should be a closed system. The thermosyphon will only work if it is fully charged with water. Any air or steam in the system and it will stop.
Are you sure? My brain agrees my machine does not...
I have noticed that with the HX not quite full (ie. when it cuts out due to low water when flushing, if you leave the lever up for longer than a second or two without the motor running, or put the lever in the brew position just before it activates the motor and let a bit of water out the group) the group heats up very quickly to 105+ when it normally sits at 98 idle and 92-96 when in use.
Remembering this machine is running off a tank it has no mains pressure to keep the HX/thermosyphon path primed in these situations. Normal or is my machine doing something it shouldnt?
