Hello everybody! I rent a house with a Vaillant Ecotec pro combi boiler installed. I live in Brussels, not UK.
Last year I had low pressure up to the point the boiler stopped working and saw the F.22 message. I searched my way through the Internet and found that I had to refill the boiler using a filling loop. My boiler has an external filling loop, a "U" with two red vannes on both sides. I was able to successfully fill it up to 1.5 bar and never looked back.
This year (around a year or maybe more than the previous intervention) I accidentally saw it is blinking 0.5bar-0.4bar and even 0.3bar sometimes. It is working as it should (at the moment) but I thought I should better fill it up before it actually stops again and show the F.22 error code. I tried to do exactly the same as last year, open both red vannes cautiously, in order to refill pressure. Nothing seems to happen. No water is flowing. I have tried with the boiler turned off and with the boiler turned on -no luck. I looked around my building if there is another vanne somewhere in the basement but found nothing (and who would have turned off any vanne and for what reason -we are only two appartments and we know each other).
I read on the internet that this might mean a faulty pressure gauge, but both the analog and the digital pressure meter show the same (and it has been like that like forever). I don't think the water pressure in the main system is lower than 0.5bar and I can confirm water flows normally in the house (as every other day).
I found this other thread and the problem seems similar -these guys advised the other person to empty and refill the boiler.
I am supposed to run a routine check this autumn but I am really puzzled as to why something that has worked successfully in the past, now seems not responding.
I have classic red iron vannes so probably we do not have a case where you should take the vanne off and unscrew using another tool.
I would greatly appreciate any help you might offer, the idea is not to get stuck with a non-working boiler some morning when you really need to reach the office soon
