Notes from the research
  • Manual PDFs are hosted on library.delonghigroup.com (De'Longhi Group asset bank); first-party status rests on linked_from (the delonghi.com support page links to them).
  • Descale and coffee-circuit cleaning are alert-driven only; no published interval per hardness level.
  • No shower screen, group wipe or routine service guidance; gasket and burr replacement are Customer Services jobs; no burr life in kg.
  • The 'Smart tamping station' has a cleaning procedure (brush, lever, tube brush) but no interval and no slug; not recorded.
