    Hi I have a vailaint turbomax boiler was working on heating but the hot water stopped working. Have stripped down the diverter valve and replaced the diaphram which had a small split and was slight perished also reaplced seals etc. cleaned the heat exchanger too. as Had similar done a few years ago now

    Re-topped the system back up but when you start up it runs for a little then blows off steam from the pressure relief valve ? Is there still air in the system have I not bled enough or have I done something wrong. any help please

    Boiler isn't circulating any water.

    What would cause it not to circulate any water.
    The pump ?

    Well given that you've just been fiddling with the diverter valve
    and it was working before on heating.

    Might be pump. Is it turning?

    Might be boiler valves if you haven't opened them again.
