actually means.
Some CM242WTXT machines use a softener cartridge in the tank. The machine tracks its use and, when it is spent, asks for a new one or for the filter setting to be switched off.

What to do when Replace water filter. Press OK to start shows on the coffee machineKind of codeMode, not a failure
The machine is doing what it was set to do, not wearing out: a rinse that runs through the spouts at switch-on and switch-off, a descale or filter reminder counting the water that has passed through, an energy-save mode that darkens the screen after a quiet spell, or a demo mode left on from the showroom that lights the keys and pours nothing. No part is needed; finishing the cycle the display asks for, or a key sequence from the manual, ends it.

in this order.
Each step comes from Bertazzoni's own guidance for Replace water filter. Press OK to start on its coffee machines. Follow it to the end: the last card says whether this is a visit.
Press OK to start the change now, or choose later.
Fit a new cartridge as the screen and manual show, or remove the old one and turn the filter setting off.
If the prompt returns right after a change, book a visit to check the settings and the tank.
Cleared?
The message is gone, and the machine grinds, heats and pours a full cup again with no new part. If it comes back within the week, or the descale or filter reminder returns straight after a finished cycle, say so in the booking.
What not to do
The line is a reminder, not a leak or blockage. A machine without a filter should have the setting off; otherwise the general alarm keeps pointing to a filter that is not there.
