Opened the isolator box last night and the neutral (N out) had indeed burnt out.
I am going to buy a new one today. Thank you all for your reply's.
One further question: Why did this happen? It's always nice to know why these things happen!
Thank you all again :)
Hello,
My electric shower has stopped working. The light on the unit is off but the light on the pull cord is on.
I noticed that when the pull cord is on and I press the button on the shower unit to on, the pull cord light goes off! I never noticed this before. Is this a clue to what...
