Subject: Sand in LaMarzocco Linea Boiler?
|
I was gazing into the sight glass of my 3 group linea the other night
and noticed some sediment on the bottom of it that reminds me of sand.
It is medium gray in color. I have a Everpure micro carbon filter on
this machine running on city water. This machine was completely
descaled and rebuilt about two years ago and gets limited use (about
10 hours a week). The taste of my steamed milk seems fine. I plan on
draining the boiler and opening the sight glass soon, but I have not
gotten around to it.
Any ideas what this might be?

it sounds like scale. check your filtration/softener to see if things
need to be changed/refreshed.
also, don't open up your sight glass unless you absolutely have too.
it's a pain to do, and a pain to get resealed (a gasket & o-ring), and
you'll need a special spanner unless you want to trash the plating
with a monkey wrench.

"Medium gray" sounds like scale.
