f 22 Fault Vaillant ecoTEC Plus boiler

My video is for all aged people to show you in a simple step by step instructions on how to fix the “F 22” fault on a Vaillant ecoTEC Plus combination boiler. You will not be able to get hot water or central heating until the boiler is topped back up. My video show you how to do that. All my videos are filmed on location. If this is not your boiler then please check my other videos. If you find my video helpful, please leave a comment. Or share it with your friends. Subscribe, so you do not loose my video.
