I have a Ferolli combi boiler which has developed a timer fault. The timer often loses the time and flashes on 0:00, as if there has been a power cut. It also loses the programmes. I reset the clock and programmes and the system works fine, until it does it again. Initially I thought it was caused by power cuts as it was an intermittent problem, however it is becoming more regular. Has anyone else had this problem? Do I need to buy a new timer? Thanks.
