Got it, that's useful context. I think the Vesuvius is pretty much exactly what I want, at least on paper. Although I have a slight preference for full manual over spring.

Reply from ACS - this does not occur any more as they extended the intake pipe

FYI

Yes, because I told them too as soon as I found out on our forum....I cannot imagine what possessed them to have the intake pipe so high in the boiler (it's the same 2.3l boiler used on the Minima), there is no chance of it blocking in the position it was originally in on the Minima? Sure, if there's a problem, or been a problem, change it...but there has never been any problem drawing water before that I know of, and I had no idea this had been done?

It also makes descaling a lot more complicated, so another compelling reason for it to be returned to the same depth as in the Minima.

I do not understand what you mean by dry/wet cycles?
Not sure about this but I recall DaveC mentioning in a clip that the gear pump has a ~35 ml/sec flow rate. I guess this should be quick enough to not leave the heating element hanging to dry. Also there should be an electronic protection via Brain Box. Strega's heating element kicks in only after water in the boiler reaches the first water level probe.

Could you please elaborate on the 0.5 l accumulation of water. Is this the residual water after purging the boiler through the hot water tap?

As I wrote earlier, the 0.5 its no longer an issue for new machines. But was noticed, due to a short pipe, not all the water from service boiler was able to be extracted.

Dry/wet cycles - if I drink 6 milk coffees per year (example) and I want always fresh water inside the service boiler, thats means the heating element will be dry - wet - dry - wet .... I am not a handy man, so want to know if this could affect the heating elemnt (rust, cracks or something I cannot imagine) Hope I was more clear

I'm confused.
Is this the pipe through which hot water from the boiler is pushed outwards by pressure difference ?
The intake pipe, for me, is the pipe that feeds the boiler with fresh water.

Intake to the steam wand or outake from the boiler I assume

I have no idea about this machine's protection systems.

Back in the days when I was using a Sanremo Treviso HX machine, that had a rotary pump with a 50 ml/sec flow rate (well this drops with hydraulics), I was diligent enough to always uncouple the heating element from mains while filling the boiler from scratch.

I wouldn't worry about rust.

Doesn't this machine have auto-fill for the steam boiler? I would think that unless you take some extra steps you can't easily leave the steam boiler empty. It would typically be full of stale water that you would need to purge before you use steam if it has been sitting there for months.

To bypass autofill just turn off the machine :) Boiler purge through water tap happens naturalluly as long there's pressure inside.
