Hi.
My mum has a Mira electric shower and I replaced the pull switch about a year ago as it stopped working and there seemed to be some charring inside and the plastic had cracked. Now the new one has broken and when I look inside the live wire has melted its plastic and is black and charred for about an inch and a half and the plastic around the terminal is cracked and burnt.
What is causing this? The shower has a separate fuse box downstairs and seems to have been properly fitted.
Any suggestions?
Thanks.
