Have been watching your videos for a while very informative and good diagnostic skills. Also just a tip you can get the pin in from the top using some bent nose pliers!

Great video, ive had a new pressure valve and thermostat i get hot water but no heating and no faults on screen just wont start up any ideas

[@thementalgasman3tgasmainte317]

Are you definitely getting 240v on switch live coming back from stat. Does the radiator icon flash I’d then be checking the parameters if you have

My vaillant increasing pressure always when even heating on? Thanks

[@thementalgasman3tgasmainte317]

If it’s going the red when heating is on then loosing pressure , generally points towards and issue with the expansion vessel

Did pcb not need programming on this valiant?

[@thementalgasman3tgasmainte317]

No mate not in this occasion

Hi All - Just to say in 95% of cases, 'faulty' PCBs causing these intermittent F6n and F7n errors on older Eco Tec boilers is very easy to fix with a common cause - (deteriorated Electrolytic Capacitors) - Please see:- kzbin.info/www/bejne/naebZnWFpNObY7s
