I have a leak from LH side of the boiler near the d h w. heat exchanger i think, it is plastic black 3 tubed chamber to the left of my boiler.
model numbers vcw gb 221 h (gc 4704414).
I believe the plastic DHW HE is now replaced with a kit.
As i have no manuals, what is the new kit, and what other mods is required if i replace it with new kit?
As everything is working OK, what are consequences if the leak unattended.
I am really not sure what some threads on the forum talk about TRV's, PCB links, and Div Valve disc.
Any advice/comments appreciated plz in advance.
My boiler is 24 years old and I have the same problemas you. I do have the original manuals but still can't ascertain what the part is

Very common to leak from these old black plastic heat exchangers. It will need to be replaced Costs about £150.00 - £200.00 . Way up the age of the boiler and if it would be worth putting that money towards a new boiler but then you are talking £1500.00 - £2000.00. Not really something you can do yourself so you will need to call a corgi engineer.
