Yes it was. I'll post back on tuesday - hopefully with the resolution :?

hi both, To clarify both circuits are protected by different RCDs (I just didn't know that earlier on in the thread).Suspecting a faulty RCD the sparky swapped them around. The problem remained. The boiler will only trip out when connected to a socket on 1 of the circuits. I have tried...

Thanks I'll suggest that to him

I could contact worcester to investigate as its under warranty. Whats confusing is the boiler works fine when plugged into another socket on a different circuit (also protected by RCD). I'll post back after further tests on tuesday.

Yeah tried a kettle on it - it was fine

nothing was connected when he found the leakage. what doesn't make sense is I plug the boiler into another socket (on a separate rcd connected circuit) and it doesn't trip. he's swapped the rcds between the 2 circuits - no change. very strange

Still not sorted. Sparky found leakage between neutral and earth when doing a resistance test. The next thing he suggested was to remove all wall sockets to trace the circuit around the house. Once he finds the leakage he suggested splitting the circuit into two. He's not coming...

ok thanks for the advice. I've think I've hit the limit of troubleshooting tonight. I'll chat to the sparky tomorrow and may post back Ta again.

The other circuit is not on the same RCD. To be honest I don't know if the other circuit is protected by another RCD - I'll have to ask the sparky tomorrow. If its not it goes someway to explaining it. Do you think the next step is to test the boiler somehow?

Thanks again for your help ok went around the house and unplugged everything on that circuit. I was quite hopeful but sadly it still tripped as soon as I plugged in the boiler. :( If the boiler was faulty shouldn't it trip on the other circuit? This doesn't make sense! The boiler is...

thanks for coming back. There's loads of stuff on the other circuit - router, clock, phone chargers - nothing major really. I think I'll go around the house and switch all of the other equipment off to see if that makes a difference.

hi there, I have this problem where my worcester boiler (42cdi) when plugged in to a circuit causes the rcd to trip. I have tested it on a couple of sockets on the same circuit that are in different rooms (i.e. so its not just a problem with 1 socket). There are plenty of other devices on...

hi there, For some reason my central heating has got a lot noisier recently - you can hear water rushing around the system. Sounds like its circulating at 100mph! I've a worcester 42 cdi combi. Pressure is about 1.5 bar when boiler is off going up to 2 when its on. I can see from a...

Ah that explains why its only forming at the bottom. What would you recommend I do to sort this out? Soffit vents?

Thanks for all the replies - I really appreciate the advise. Having read up on it I minded to agree - its condensation. We do have a "perma-vent" breathable membrane but I guess its not breathable enough and I should be looking at extra ventilation. I was up there lagging some pipes which...

hi there, About 3 months ago I had a loft conversion and new roof - i.e. membrane and new tiles. Whilst poking about in the loft today I noticed that there is a fair bit of moisture coming through the membrane. This is evident in a few different parts of the roof. (see pics) This looks...

I've got the same dilemma. Did you seal yours - if not how have they got on? -H

thanks for all the replies. Just to let you know I emptied the trap, cleaned the flue (from outside) and bled the radiators. Now seems to be working ok (fingers crossed). My best guess was that it was an air lock. Cheers again. Huw

hi there, I've got a problem with our worcester 42cdi boiler in that the central heating doesn't work. When you switch it on the flame light comes on the boiler shudders and then the light goes out. Its does this about 4 times and then the EA error comes up. Hot water works fine. I have...

hi there, I've started painting my golden pea pebbledash and am keen to get it done in as fewer coats as possible as its a nightmare! I've been applying a heavily watered down coat to try to fill the crevices before following up with a thicker coat. Its sandtex smooth and I've been applying it...
