I use a pre-paid gas in my house.I topped up the gas today as it had completely ran out but I can't get any gas into the house, I don't know how to bring it back to function.The model of my Modena 80 E.
You need to reset the boiler,if you have a reset button press it or turn it towards the R direction and hold it there for 3 secs OR turn the power off and then back on.
