“After every 200 coffees, rinse by delivering about 0.5 litres of water from the spouts (press the coffee button without using ground coffee).”

Notes from the research
  • The manual PDF is hosted on library.delonghigroup.com (De'Longhi Group asset bank); first-party status rests on linked_from (the delonghi.com support page links to it).
  • Descale is alert-driven only; no published interval per hardness level.
  • No backflush, shower screen, or routine service guidance; gasket replacement is a Customer Services job.
