F.22 Vaillant EcoTec Plus 630 - can't locate filling loop

[johnnycarmello]

Hello - I have an f.22 error on this system boiler, 0.4 bars. Just moved into this house so not certain on how everything works. There are no taps under the boiler to add more water.

There is a hot water cylinder in the cellar so thankfully it's just heating that we have lost.

With this boiler would there be filling loop somewhere else that I just haven't found, or do I need to adjust something under the boiler with a screwdriver?

Greetings Johnny, Have a look in the cylinder cupboard.

Thanks - will report back. All going well, I will hopefully achieve two things. Repressurise the boiler, and get over my fear of the tiny dark cellar....

It’s probably with the hot water cylinder but could be behind the washing machine

Found the filling loop down in the cellar with the hot water cylinder! Got the heat going again!
Thanks folks
