Notes from the research
- Bezzera's own manual is only reachable through retailer-hosted copies (bezzera.it gates manuals behind spareparts.bezzera.it login), so every value is basis community although the text is Bezzera's.
- No fixed detergent-backflush, tank-clean or filter interval: all three are owner-configured counters on the touch screen.
- Shower screen replacement, steam wand deep clean and a professional service interval are not stated.
- The manual is the combined Matrix/Duo edition covering MN and DE; the text used applies to both.
