Immergas eolo star error code 10, which does not disappear at the correct pressu

Hello. As in the subject, I returned from holiday after a week and a half to the apartment and found a surprise in the form of error code 10, which according to each instruction means too low pressure and it was in the range 0-0.5, so immediately as I saw it I increased it to correct, the error occurred earlier, however, it was enough to repair and when the pressure increased to good everything started to spin. In contrast, now that the pressure is correct, error code 10 continues to flash red. The restart button has no effect, nothing adds or changes. Restarting is normally all the lights and pictures light up, then the code something like "nC" or "nG" and immediately after that again error code 10 and so all the time (from the very beginning of the display flashes red), and in the house ziemimno. Ever struggled with something like that? Best regards and wish you a happy new year.

The sensor may hang, muddy or break down. Try to allow water up to a maximum of 2.5 bar. But do it slowly. If the error disappears, drop the water using the radiator vent to a value of about 1Bar.
Do you often allow water into the CO system? If the water is running out then the cause must be found.
