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).
  • The EU/UK EC9355 pages link only a non-English multilingual manual; the US EC935X manual and quick start are used.
  • Descale and coffee-circuit cleaning are alert-driven only; no published interval per hardness level.
  • No shower screen, group wipe, water tank or routine service guidance; gasket and burr replacement are Customer Services jobs; no burr life in kg.
