URGENT HELP NEEDED-COMBI IS LEAKING WATER FROM INSIDE BOILER

[CANIFIXITNOICANT!]

Hi I have a 3 5 yr old Biasi prisma boiler and up until last week was working ok. But yesterday i noticed water dripping from inside the boiler,it looks as if it is coming from somewhere above the hot in/outlet pipe. There is a compression nut on the pipe but its definately not coming from that. I have turned it off but as we have a 5 yr old its really cold and was hoping i could maybe fix it raher than getting a repair man and spending out £ i dont have!
Many thanks

Well you can't fix it until you identify where it's coming from. You need to examine the manual and have a very careful look inside. If the system pressure drops, it may be from the CH side. If not, it's probably from mains pressure side, in which case turn off cold mains inlet to stop leak and continue using boiler for heating.

Time for a torch and a small mirror parhaps?
If you are sure the water isnt dripping onto any electrics then you could probably keep using the boiler, just wrap a bandage near the leak and drape the end into a bucket or something.

the hot in/outlet pipe.

It will be leaking from the screwed joint on the left at the base of the 15 mm tube leading up to the AAV.

Thats assuming the AAV itself is not leaking!
