Having been on and working all day the red light is now on (not flashing) and the heaters have gone cold. I have pushed the reset button but no joy - any ideas, in the past it has fired up when the reset button has been pushed?
solid red just means 240v supply to boiler, its not locked out. you are not getting switched live to turn it on, so will probably be a fault system side,
although you have mentioned youve been haviing to reset, so you might have a problem with your pcb as well, although this isnt whats causing it not to work, just the intermitant lockouts...(red flashing)
