Hi, I have an Ideal Logic combi 30 which is showing the F1 errror code. The pressure is showing as fine (between 1.5 and 2) and I have bled all the radiators. Does anyone know what could be wrong? Many thanks Zoe

Ideal logic F1 error - presure is between 1 and 1.5 bar and all radiator valves are open and system has been vented, low pressure senser on the top of the pump assembly the connections could be loose or faulty needs to be replaced, new pressure senser.
