    Hey,

    I've got a Baxi Combi 105 HE, and there's a component at the bottom that drips water. Not a lot, I'd say 1 drop every 10 sec, but annoying though. Here's a screenshot from the manual with the part I mean:

    Is this something I can fix myself? I can do basic plumbing and central heating DIY stuff, but I'm in no way an expert. Since a boiler is water, electricity, gas and combustion altogether I'd rather not mess around with it.

    Thanks!

    Sounds like you need a DHW diaphragm kit mate. Should be part number 5111137.

    Sounds like you need to get an engineer.

    If you are not confident or are unsure then as above. Please get yourself an engineer out.

    As above if it's dripping then it'll be the Diaphragm in the Diverter valve that needs changed. Not a big job but not a DIY job either

    There is one now :)

    What does this valve or diaphragm do exactly?

    Controls the boiler sorry can’t go into details as your not gas safe and we don’t allow boiler repair advice on the forum (open part)

    No worries.

    I've recently upped the temperature of the central heating of the boiler. Could that have played a part in this issue?

    It’s just normal wear mate.
