Hello,
I woke up today to find that my Valliant ecoTEC plus was showing the F22 code. After lots of googling I realise what the problem is and have tried followed instructions to turn the grey knobs underneath the boiler to re-pressurise it. The instructions I found said that I would hear water moving when I turned them, which I didn't. The pressure rose from 0.3 to 0.6, but that's it. Am I missing something or is there something else wrong?
Thanks in advance.
