Hi, I wonder if anyone has any advice about the micro Genus 23 combination boiler. Since we have had the boiler installed it seems that it has been nothing but problems. We have had a new pcb installed, dhw heat exchange, and temperature probe (done dec 2007). Now we are having issues, that when the heating is on, even though it is only on the minimum setting, the heat increase dramatically, shooting the temperature up to 80 for a while, and it then decreases. This even happens when then heating is on timed, eg from 9 - 4 during the day, and it comes on sometimes during the evening, this often happens when the hot tap is being run. Anyone got any advice apart from scrape it ???
Thanks
Thanks
