Hello. My 24i (natural gas, about 6 years old) has lost all hot water. CH is fine. It happened suddenly, no flashing lights, no lights at all. No leaks, good gas and water pressure. Suggestions from the manual: harness, pcb or turbine. The pcb was replaced a couple of years ago. I'm a competent diy'er, but wouldn't wish to attempt anything tricky. Any ideas? Any really cheap plumbers in the Bristol area (I'm not being cynical, but I really am borassic!)? I've been decorating in the boiler area recently, so loads of dust. Might that be a cause? Any help would be massively appreciated. Thanks, Kevin.
