I have an Alpha CB28 combination boiler and it is not working at all. The bottom neon indicator light is flashing every second and the helpline suggests it is a temperature sensor fault. I have had it replaced and it still does not work. i have also replaced the flow switch The boiler appears to fire up for a few seconds and then it clicks off again, so the light is only staying on for a short time
