You've got to disassemble the boiler and remove the scale from there. I run a Gaggia Classic at home with really hard water and my machine literally stopped flowing due to scale buildup. Once I fully pulled it apart and scraped all the scale out of the inside of the boiler it started running flawlessly.

Would sound absurd to all but the nerdiest, most dedicated, but have you considered making your own water[0]?

Or just buy bottled water. If you're only doing Espressi, a 1 liter bottle can take you a long way and comes in under 1 Euro.
For a daily thing like coffee I gotta set myself up for the most sustainable path or it feels like I'm accepting the waste
Very neat!
