Just wondering if anyone has come across this. We have an Ideal Icos (installed June 2004) that has given us untroubled service for the last 2 1/2 years. A few weeks ago the trip went on our Circuit board and we eventually isolated the cause to the boiler. Water was dripping inside on to an electrical connection. We called the plumber who installed it who checked the flue, found that a seal had been twisted when fitted so resealed the inner and outer sections with silicone (I would have preferred him to get another proper seal!). He also refitted the flue so that it was tighter on to the roof, but it is still happening. The Ideal techie suggested the sump might be blocked but the Plumber had serviced the boiler and cleaned out the sump. It is only intermittent, maybe once a week or so (we have now covered the electrical connection with plastic!) as if there is a build up of water/condensation coming from somewhere inside. We've left the bottom off the boiler to see if we can see where it is coming from but it hasn't helped. I still have my doubts about the flue, but wondered if anyone else has come across this problem?
PS. Since the plumber serviced the boiler it now occasionally fires with a loud "whump", could it be that he hasn't tightened the cover/seal properly?
