F C CODE worcester greenstar boiler?

We had this problem and it was just that the solder on one of the 4 connectors on the text display unit that had worn away. A replacement text display would have cost approx £300! Unplug the text display and check the solder on all the connectors - if any of them look worn, apply a little solder and recommect the yellow plug - it worked for us

I think there is air trapped in your pipes and/or boiler you may want to try and bleed all your radiators first, if that doesnt work I think there is a valve under the metal housing of the boiler (near the top) but I wouldnt risk you do that yourself. Then again I could be wrong, you are better off calling a professional to do this for you.
