Hello. My boiler at home has been playing up the last few days giving me an error code F.22. Looking through my manual it says it needs topping up as it's dry. My pressure should not drop below 0.5 bar and mine is showing 0.4 bar. I have a loop pipe on my system for the water but turning either one is not doing nothing. It's been very cold these past few days and I would love to get his working again. Thanks for any info. Mark
