with winter on its way and my girlfriend very pregnant our boiler is deciding to play up. Have a potterton lynx, and it has been working really well for years. Until now. On occasions the demand light comes on and whether the central heating/ or the hot water is on, the lowest light is on. Therefore, water or heating is cold. However if I give the front pannel a tap (or light whack) it starts up and stays on for hours sometimes days without any problems. Please guys any ideas??
