Our Flexicom cx combi boiler is still providing hot water but all the radiators are cold. The boiler has a pressure of 1.0 which is apparently the minimum it needs to work, no error messages & turning up the thermostat hasn't helped. We think it started after our recent annual gas check, but have barely been home this week so aren't certain. We're here now though and it's COLD!
I know we ought to simply call the engineers but they could take three days. I know how to take the front off the boiler - is there anything obvious I could try?
TIA!
