How to re-pressurise Vaillant combi boiler. F22 fault code.
Showing you how to add more water to your heating system. This may have to be done occasionally.
It doesn't mean your boiler is faulty, there are a few reasons this could happen, it may be there's a small leak on your heating system or your expansion vessel requires recharging or it could simply be the heating system that has lost a little pressure gradually over time. Re pressures and motor the boiler over a few days/ weeks. If it continues to lose pressure you should call a heating engineer to investigate.
