Help needed......my Mira Sport Shower has started turning itself off when I switch it on. It doesn't seem to matter which power setting I choose (High, Medium or Low) within 10 secs it just stops, as though you have pressed the stop button. I have contacted Mira to ask their advice and they weren't really very helpful. They said it would be difficult to say without looking at it, and asked if I wanted to book for an engineer to come out and look at it....but at £145.00 this isn't an option. All I want, is for somebody to just point me in the direction that it could be. Water does come out when I switch it on, so I dont think it could be a plumbing problem.....I think that it may be an electrical problem, being that it switches itself off. Any help or advice would be greatly appreciated
