I have a potterton suprima 40 which constantly fires up every few minutes. It flashes green for 2 minutes, flashes red and green for 10 seconds then fires up. The boiler stays on for a couple of minutes then the process starts again.
I have hot water and heating so could this be a faulty boiler stat. The PCB was replaced about 15 years ago, the boiler is 20 years old.
Thanks.
