Purpose and fit

Check the documented application.

  • The complete EP5447/90 model is documented; the 5400 marketing family alone does not establish every regional variant.
  • CA6903/10 is a single AquaClean filter. Other pack suffixes need a contents and reference check.
  • The manufacturer US page is marked discontinued; this page confirms identity and the documented filter system, not current stock.

Before ordering

  • Installing a filter without completing the machine's activation procedure can lead to incorrect filter tracking.
  • Do not present AquaClean as a substitute for every cleaning or descaling procedure.

A product reference and a shared brand or category do not establish fit for an unlisted machine. Keep the exact machine generation, market, size and attachment requirements from the manufacturer documentation.
