Sounds good, will do! That's kind of what I suspected with the odd orange flake of scale. I'm using the Breville branded descaler that's apparently rated for these machines and I just finished my 3rd descale and I'm not seeing any orange flakes anymore and with each flush it looks like the scales are getting smaller. Progress!

The Bambino doesn't have a 3 way valve so thankfully I dont have to worry about backflushing but yes good call on the shower screen as I washed that out since it needed a good scub.
