The Jura D4-D6-E6-E8-J6-S8-WE RFID CPU 230mm is located underneath the Water Tank. It connects to the
RFID Coil and detects that the
Smart Water Filter (ENA 8 uses the Smart Mini Filter & commercial models use the Professional Smart Filter) is inserted into the Water Tank. The Jura coffee machine will notify the user when the Smart Water Filter needs to be replaced.
