Vaillant SINE 18 Combi Boiler - drips from unit

[padsmith70]

I have a Villant SINE 18 combi boiler model VCW sine18

I have some history of the unit not firing backup after being drained. It seems to get air in the system so wont fire back up. Only way is the turn on the heating and open the screw on the pump to release air.Eventually all is fine.
Now, I have water dripping from a gold coloured connector on the bottom of the boiler.
I have been looking for a diagram showing parts of the boiler so I can go to a plum center to purchase the correct parts. Does anyone have access or know where I can gain access to a document shoing each part.
Thanks again

Not a hope!

But you may have some difficulty with a boiler that old.

I think that I am correct in saying that all the vaillant specific parts under the boiler were plated with a silver colour.

I would therefore expect that its a generic plumbing connector.

In any case a "leaking connector"can usually be sorted out by removing it and cleaning and refitting it with new sealing wasjers.

These boilers seem to go on and on and I have never yet failed to find a spare part.

After draining down a CORGI should remove the combustion chamber and bleed air from the nipple on the right of the primary heat exchanger.
