If my videos help you, if they perhaps save you from a call-out fee or a cold night or a chilly shower then you could show your thanks by buying me a cup of coffee and a slice of cake. That would be lovely and much appreciated. Just click the link and make a small donation. I really do appreciate your support. And I can keep making videos to help you. Many thanks, Mark.
Vaillant uses the F22 fault on most of there boiler range. Look though the titles and find the boiler which is the same model and looks the same as your boiler. If you don’t see your boiler try watching one of the other videos as may help you fix your problem.
