Vaillant Ecotech plus 624 Water Pressure Filling Loop

[nessy4646]

Hello
We had a radiator fitted this week and now have F22 fault showing. We don't appear to have the normal two taps to turn... here's a photo of what is fitted and after much research I still can't work out what I'm supposed to do with this!

Not all have x2 taps, yours in just 1.

Turn the one black tap to re-pressurise the boiler. On a separate note that red grommet where the cable entry is needs sealing on your next service.

Hi Chris
Thank you for your reply. I had already turned the black tap and yes it filled with water but the bar pressure didn't move, although I only ran it for probably 10 to 15 seconds. Bit nervous of going for too long!

I have done it.. I stopped at 1.4 bar and left it to settle before I put the hot water back on. And yes, I will make sure the plumber sorts out the grommet thank you
