I've been having problems over the last couple of days with my boiler. It keeps going off at random intervals outside of the programme settings. The heating and water start up ok when required to do so but then go off after about 1 hour. When i press the advance buttons to restart it then nothing happens. I've reset the setting but this doesn't seem to have had any effect. I have taken off the front panels to check the pressure but cant find the gauge. Also i can now only heat the central heating system when the water is also being heated. If i turn the water off then the heating also switches off. Getting frustrated now!! (Any clues??) My thinking is that the system is maybe overheating quickly but cant think why?? Cheers....
