silly question check you do not have the mode selector switch off the boiler in hot water only position if that is not the case it sounds like the boiler is not being sent the message that c/h is required from the timer the reason why it works for 15 mins is that you are putting the boiler in to test mode which should only be done when testing the boiler during its annual service
