Wow, It's been a long time since last update and a lot has happend since then.
I was newer quite satisfied with the steaming performance on the Giotto Classic and went
through all kinds of tests in order to improve this. I tried descaling and changing the boiler water level but it didn't make much difference. After speaking to fellow coffee freaks I came to the conclusion that the ECM Giotto Classic Steam and Water Valves are simply not cut for the job the machine is able to deliver. After seeing a fellow coffee nerd at the Swedish coffee forum http://www.rigtigtkaffe.se making steam mod using Izzo Alex part, I believed I had the answer.
The Izzo valves lets out more steam and as a bonus you get ball jointed mountings.
So lets get started.
Here you see the Giotto Classic before Waterwand was replaced.
This is the new and complete water wand

The old valve taken out
Replaced with the new valve - Voila!
Here's the final result! Replacing the steam wand is exactly the same operation. You may however need to spend more time adjusting the cobber pipes though.
Here a short video of the steam power after the mod.
