    Hi,
    I have a Worcester 37cdi combi & over the last couple of weeks it has been cutting out with the E9 fault code showing.
    This evening I have reset it numerous times.
    Any suggestions what is causing this ?

    What's the pressure at ? Should be a dial on the front of the boiler

    Is that with the heating warm or cold ?

    Heating is warm. It’s been on since 4.30pm.

    I would say up the pressure upto 1.8-1.9 bar

    I have upped the pressure but as soon as i turn the hot water on it cuts out with the E9 fault code.
    When I press reset the green light is lit indicating the boiler is lit but there doesn’t appear to be anything coming out of the flue although the rads are getting hotter.
