Hi,
My Vaillant's pressure is going to zero overnight with all the symptoms that match the FAQ entry "REPRESSURISING THE PRESSURE VESSEL".
The procedure seems pretty straightforward and I would like to try it. I need to open the left hand side of the boiler but before I start unscrewing things I wonder if someone can tell me how do I remove the cover?
