When left overnight boiler will light and run as normal for between 15 and 30 minutes occasionally relighting as required.Radiators will heat up
Then the green light begins to flash but soon the green light stays on and the red light flashes with the fan running -- it will stay doing this untill we turn off the timer and reset.
If left for a few hours we can get it to relight for a few minutes
The pressure switch has been changed but could it be the flow switch ?
