Restore my u tube function which has disappeared?

The ventilate sign appears as an error message to tell operator that the flow of water is reduced. I can tell that the machine has not been descaled or was descaled using unscrupulous products that are labeled as descaler but they are not.
Because the sign disappears at this time after flushing water through the steam pipe, the flow restores the sensing that water is flowing normal. This "apparent restoration" of water flow is without any back pressure. The espresso function is restored for limited use.
This error code if not corrected immediately, it will not disappear and not allow any function even after flushing water manually.
The flow meter registers the quantitative flow of water as programmed for espresso.
Please descale the machine as soon as possible. before the 'Ventilate' error message stops all functions.
This is a well designed machine. Needs more attention to maintenance.

You need to perform a firmware update
