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).
  • No English instructions-for-use PDF is linked from the EU/UK EC9155 pages (only safety warnings); the US EC915X manual and quick start are used.
  • Descale is alert-driven only; no published interval per hardness level.
  • No backflush, gasket, shower screen, group wipe or water tank guidance; burr replacement is a service-centre job with no kg figure.
