We had a new cylinder installed just over a year ago and water has been heating up overnight (using economy 7) fine until a few days ago when this no longer happens. We've had the element replaced by a plumber and as he said that no power was getting through so an electrician took a look and confirmed there was power getting to the element but that it was tripping out the fuse and that it's the element/heater at fault. Am now confused as to what the problem is and who I need to get to fix it? Electrician or plumber? We've looked for the Economy 7 timer but can't find one as the wires go straight to switches so gather we don't have on and it's automatic (switches have always been left on). Any ideas?
