New immersion element not working

[john13]

Sorry

I should have said that the neon lights up on both neutrals in and out of the switch.

In that case it isn't the switch, but there is a broken/loose connection in the neutral path between the switch and the consumer unit.

When you turn off the MCB (or pull the fuse) at the CU, does it turn off any other appliances or socket outlets?

Nope it appears has its own fuse.

If the immersion supply,cable goes directly to the consumer unit then the neutral connection has either come adrift inside or the cable is broken somewhere.

We are now at the situation that you will not be able to isolate all live feed into the consumer unit. In that case I dont think that you will be able to do any safe working and in any case I doubt your competence to do that safely.

My conclusion is that you need to call a competent electrician to open the consumer unit and see why the neutral connection is missing at the spur switch.

You mentioned rewireable fuses earlier.... I don't suppose you have an ancient installation with fused neutrals do you? It's a long shot, but I think there are still a few about.

Did you ever diagnose the old immersion or thermostat as faulty, or did the main fuse blow?

The trouble with a neon screwdriver is that it doesn't tell you the voltage - only that there is some.

So far, I would say the most likely scenario is a loose neutral at the neutral bar in the fuse box.

Time for a muppet like me to call for a Pro.

Thanks you all for your advice, I have learnt a lot. The most important thing is know your limitations!.

Thanks
