Thank you Paul and Hamid for that information. It is greatly appreciated.

I will look into finding that partial short circuit within the heater. It has been rewired with modernish white cable with a blue ( live ) brown and yellow earth.

I hope I may be able to fathom out where problem may lay with the wiring system.

Thank you for your help. 👍

I would also like to add, fortunately both coil elements seem to glow red on the 1500w setting, and remain dark upon the 750w setting.

Thank you.
