My son has just purchased a house with a 4 year old Worcester 28CDI RSF boiler. I removed the radiators while decorating and have now put them back on. The boiler pressure is now 0. I have put the white T shaped key in hole, turned to lock it and opened the grey valve as the instructions say. Nothing happens, no pressure increase. I have removed the key with the grey valve open and water runs out of the hole where the key goes, so water is entering the boiler.
Any ideas of what the matter can be, as Worcester want £185 to come out and look at it.
