Hi Everyone,
I'm new to the forum. I have an f22 fault on a Vaillant EcoTech plus 624 combi boiler. I have checked out the posts on this fault and think I have isolated to the problem to de-pressururisation due to the wing nut connections on the filling loop loated on the Unistor tank getting knocked loose and leaking. The pressure dial on the front of the boiler looks like it is at zero. The digital read-out is saying 0.4 bar.
I see that the solution is to re-pressure the system and bleed it using the P0 function. Can anyone tell me how to re-pressurise the system. This info is surprising absent from any documentation and I can't see it on any posts.
Thanks for your help.
Cheers.
