has anyone any experience of this. The boiler is 14 years old and has only just gone wrong. when the boiler engineer looked at it he found there was 240v between the neutral and earth inside the boiler unit.

That's what I saidOr reversed Polarity
I'm sure your original post said "Reverse polarity" That's why I added the d, still never mind Eh.That's what I said
He is expecting me to resolve - I am insured so can get the tradesman in bit it is all taking time. See my longer post a little bit below.Hi Brian and welcome to the forums...
What did he do about it? Or is he expecting you to resolve it?
see my longer post below - I have checked at the fused box.If its only been tested in the boiler connections, and not at the supply switch/fuse, then maybe something has fried in the PCB and shorted out?
The boiler would probably work fine with reverse polarity, as would a lot of other appliances.
What needs to be done next is an electrician, not a boiler engineer, go and test the supply with the proper test equipment.
Many thanks Westward10 - Its only the wires that go to the boiler from the fusebox that are reversed. All the inline stuff seems okay. so I figure it will just be a case of swapping the live wire to the live load slot and neutral to the neutral load slot and voila. I would have thought a boiler engineer would know that as it is pretty basic - but maybe I am expecting too much. Electrician is coming out Tuesday night - Probably be a quick and easy job for him.Things seem a bit clouded with neutral connected to live load and voltage between neutral and earth, a good electrician will resolve this.
Is it just me that thinks someone who fits boilers or heating systems controlled by electric pumps and switch systems should know and be competent to do the wiring?
Precisely, if GasSafe, that should include being qualified and competent to do the sparky bits of the equipment.Apparently we are not allowed to open up a boiler to access the connections unless we are GasSafe… Should be the other way round as well. They shouldn't be allowed to touch the electrical side of things.
If there is a gas leak, God forbid, It will be a dodgy electrical joint arcing that ignites it.
No - I am with you one this. This particular issue is so basic yet I have been left for another 4 days with no heating or hot water. I just get the impression everyone is running away from the job - any excuse?Is it just me that thinks someone who fits boilers or heating systems controlled by electric pumps and switch systems should know and be competent to do the wiring?
