What it means
De'Longhi explains the message appears when the water softener filter has been used up. According to its manuals the filter lasts about two months with normal use, but if the machine is left unused with the filter fitted it lasts three weeks at most; so it asks for a change after two months (see the date indicator disc) or after three weeks without use. The change includes activating the new filter, telling the machine in the menu and delivering hot water. If you prefer to use it without a filter, remove it and notify the menu. It is not a fault.
