Vaillant 630 weeping cracked plastic manifold

[Boltondrew]

Hi All - has anyone else had weeping from a hairline crack in the black plastic manifold where the flow comes out of the burner? See pic. Looks like you can replace the whole thing, but can’t find a part number. Can anyone help? Might just be calling it the wrong thing!?
Thanks,
Andy

New boiler and tbh you shouldn’t remove the case / front cover

Hi - not a new boiler. Several years old. Have already had to replace the PRV a few months back when it failed and flooded the boiler room. Now a new leak. Or maybe it’s a consequence of the pressure going too high when the valve failed and stressed the plastic. Warranty is long gone. I can see where it is leaking. If it’s repairable I’ll try and repair it. If I didn’t think I could, I would be calling an engineer and not posting on here. I won’t be messing with the burner or gas. Happy to be told it is totally beyond me, and only a Gas Safe engineer should be touching any part of the boiler.

Combustion products are on the other side of that plastic so Gas Safe it must be.

Ah - ok, that makes sense… not great news, but thanks for your advice! Yeah - now realised that would need whole new heat exchanger as it doesn’t look like the plastic section is available separately. I could drain down and epoxy the crack… but then Sod’s Law it would go and burst on Christmas Eve! Looks like the wife is getting a new boiler for Christmas this year then!

Plus one for shauns post for new boiler as parts as over £500 it’s a full heat exchanger. So not for anyone who isn’t gas safe registere. Try Vaillant see if they do fixed price repair.

Thanks again - reading the small print Vaillant exclude the HEX from fixed price repairs..,
