De'Longhi Magnifica, Dinamica and PrimaDonna error codes
De'Longhi shows words, not codes, on most machines. Third-party repair sites also quote numeric codes (such as 1101, 1454 and 3963); we found none of them in De'Longhi's manuals, so treat those numbers as unofficial.
Fix steps are the same across ECAM (Magnifica S, Dinamica, PrimaDonna) and ESAM (older Magnifica) machines unless a page says otherwise.
