Nice one!!! I was almost frozen solid, been sat in god knows how many layers of clothing all day until something in my head told me to ask the internet, thankyou so much ...F75 - Grrr!
Hi, i have this model and the pressure too high and it keeps rising, any suggestions as i cant get it to work, if i turn my hot water tap on, the boiler clicks of.
@@marvellousmusic4336Did you get the problem sorted, on your Vaillant pressure rise? I reckon the filling loop taps don't last long, if they're used too often & they both pass water into the system and cause over pressure & it's released then released through the prv & the process starts again!!
@@marvellousmusic4336 A retro fit filling loop can be fitted across the mains cold supply into the boiler & the central heating return pipe....preferably under the boiler, then the existing Vaillant filling loop taps an be left in the "open" position.
Not the most helpful video! No speech, doesn't explain what is actually happening when that code is selected and doesn't show location of an air valve.
