Today I partially emptied the central heating system (1st floor and loft) so that I could disconnect an old towel rail and install the pipe work ready for the new towel rail. All went well and I have two capped pipes sticking out of the wall where the new towel rail will be fitted.
Having re-filled the central heating system, the boiler is playing up and refuses to heat the water or the radiators. I noticed it was giving an S.54 message, but after turning off and back on it is now displaying F.20. This has been going on for about an hour now.
There's a lot of splushing sounds going on in the boiler, so I guess there's some air in the boiler, but the pressure is at 1.4 bar.
The boiler is a Vaillant ecoTEC plus 637.
Any thoughts on what the issue might be and how I can get it back up and running? My gut feeling is that the air needs to be purged from the boiler, but I'm not sure how to do that.

So, I found an article about running the P.0 test purge program on vaillant boilers after the system has been re-filled. Although the article related to F.76 fault codes, the advice for running the test purge program was to purge air from the boiler whenever the system had been emptied and re-filled.
Unfortunately it didn't make any difference. Tried turning off and back on again but I can now hear "kettling", so I've turned it off and will have to wait until Monday to get my heating engineer out to look at it unless someone can suggest something I can do to clear the air from the boiler.
