Potterton Promax Combi boiler with E119 error message, pressure below 1 bar. Repressurising presumably needed Can anyone help? After 10 days of being away and having the thermostat right down to 10 degrees C, wherein the heating presumably hasn't come on at all as it's been quite mild, I've come back to find the E119 error message and pressure below 1 bar, so boiler won't operate. I assume I need to use the taps on the filling loop to repressurise, but I've no idea which 'taps' are which, as I can see five black taps/valves on the underside of the boiler. Any help would be greatly appreciated.
