Ravenheat csi Low Nox boiler problem?

Hi
I am not a plumber nor do I claim to be and I am hoping for assistance
Our boiler has been absolutely fine till this evening when the gas went off (card meters in a new rented property). Got more credit put it on and now there seems to be no power in the boiler, I know this is electric supply not gas but for some reason this is when it happened. There is a red light showing but other than that there is nothing else lit up, no digital display, turning the system on and off does nothing and now I am at a loose end. I have a one year old son as well as five other kids as well as myself and my wife and we need baths and showers as well as heating someone please help.
