So to update on this - there is no hole in the tubing, it’s just black marking that you can see in the video posted earlier by MRS.
It’s escaping from just under the bit that you push to insert the tubing.
Will this just be a case of replacing that part u think?

    Should just be able to remove it from the boiler, clean up the threads, wrap with PTFE tape (probably 7-10 turns) and then replace it.

    When removing, get a spanner on it and try to shock it off (sharp knocks with a heavier object), not torque it off.

        DavecUK Thanks Dave. So grip the whole part at the bottom and knock it loose? What’s reason for not removing it normally just out of interest?

            It’s loosened up a bit but struggling to get it out - will keep hammering away

              DavecUK might have to take this somewhere to try get it sorted - it’s loosened up to point where I can turn it with fingers, but only moving ever so slightly back and forward.
              Is it normally quite hard to remove it?

                  Ando I’m confused, you should be able to remove it with a spanner easily now….video please showing exactly what’s moving backwards and forwards. Because you don’t want to pay £80-100 for a 5 minute job.

                      There wasn’t anything obvious scale wise - the part has been cleaned, replaced and same problem (see video). The small top piece that you press on to remove the hose doesn’t feel right, almost a bit flimsy

                        I should add - this leaking happens when it’s heating up. It stops once up to temp.

                        Same problem on mine - part is MC935F Quick Joint

                        This forum is an inspiration. First leakage issues, and no panic. I imagined a @DavecUK character standing next to me and asking what investigations I had done, with a reassuring voice asking me to show the inside of the machine, that the leak should be pretty obvious. Top off, spot the issue almost immediately. Quick read of forum and find similar issue, identify part… Part is in stock at local retailer, off there tomorrow morning.

                          jcb1973 Nice one! Once new part was put in it resolved the problem, machine running well again.

                            Same - a very quick fix. All working again!
