Vaillant Ecotec plus 628 f.22 error code

Postby TomW » Sun Apr 01, 2018 10:15 pm

Hi

Our combi boiler is presenting the f.22 error code for low pressure. I can see from the gauge that the pressure is 0.3 so I need to re-pressurise the boiler.

Having thoroughly read through both the manual and watched numerous tutorials, it suggests that this is a relatively simple process... However our boiler doesn't seem to have the grey levers that all the guides say it should that I need to turn to allow the pressure to increase to 1.5. I also can't seem to manually adjust using either a screwdriver or pliers. I really don't want to call a plumber out for something that should be simple. Any ideas?

Hello and a warm welcome to the forum
Hopefully you have sorted this by now. If not, look for an external loop with handle/s, or screwdriver slot to turn. There may be a small loop on the boiler, in the shape of a small pipe. It could be the handle has fell off, in which case you can use pliers.
Thanks
