    Hi everyone.
    I have the old style boiler, basically last year it started not working after being on for 10 mins.. Replaced the pump and 3 way port valve cleared the lines, bled everything, cleaned it all out Etc. Literally done most things.

    Basically it will work bit o my if I manually position the 3 port valve with the actual valve control taken off. It doesn't seem to change between heating and hot water. Is this a programmer issue or a pcb issue sitting th boiler, it can't be much else, surely.

    Thanks for any help in advance. I gave up last year and spent the whole winter with the Emerson on, paying for it now.

    Has the system been vented properly and as above, both pump valves open? 3 port wired in correctly? Could be a timer issue?

    Could be possible that you have wired the 3-port valve incorrectly, also the programmer could be done for.

    How about phoning a heating engineer, after all, that is what we are trained to do :)

    You've put this image in my head of a long chain of heating engineers, each one phoning the next for advice, until the last one calls the first and the circle is complete...
