    Hi. I have a Baxi Platinum 28HE Boiler. The CH works fine but when I put any hot tap on in the house the boiler fires up as normal but I only get hot water for a couple of seconds then it goes cold.

    I have replaced the diverter valve and the heat exchange but still no joy. What else could it be that's preventing the hot water coming through.

    Thanks in advance.

    Does the central heating work, if not try changing the flue fan or lubricate the bearings.
