Hi there, I know this is a whitegoods forum, but I’m really stuck with a problem on my worcester bosch 24i RSF combi-boiler. Can anyone help please? There was no hot water, no pressure on the gauge, so I topped it up with water, which started leaking out. I took the front panels off and found that it’s leaking water from the automatic air vent. There is a clear flexible tube underneath this, that I think may be a vent, which is also filled with water, I don’t think it should be. I think it’s been seeping water from the auto air vent for a while as it has some corrosion round it, and on the casing underneath. There was no flame on the burner. I’ve isolated the electricity now. Any suggestions gratefully received.
