Step-by-step guides

What the manual does not say

3 jobs with nothing stated
  • Backflush (water)
  • Group head wipe / flush
  • Water filter / softener replacement
Notes from the research
  • Values follow the 2023 Linea Mini manual; the original (2015) Linea Mini manual on home.lamarzoccousa.com was not re-read for differences.
  • No water-filter cartridge or replacement interval and no plain-water backflush are stated.
  • The technician checklist is not dated to a Linea Mini generation; its 3-4 month cadence is aggressive for home use.
