    F75 fault with Vaillant when pressure is okay

    Can someone help me understand what could be causing this fault? It only seems to happen when the pressure in the boiler drops below around 1.5 - 1.7 bars otherwise it works fine. The boiler is a Valiant Eco fit pure 835 and the building is a 3 storey house with 10 radiators. Thanks

    Vaillant eco tec pro 28 F75 fault code.

    I have a vaillant eco tec pro 28 that is coming up with the fault code f75. The system needs to be pressured to a pressure of 2.3 bar or above to get to work.
