No power to Boiler

Our boiler has gone off, no display to tell us a fault code. We have changed the fuse. Green light on wall controller does light up to show wireless connection. HELP! Boiler was bought in 2014 is it an Eco TEC PRO 28.




Hi Anne,

You have either lost power to the controller or the controller is damaged to the point where the display is not showing.
