We have a Greenstar 30 Cdi Classic, wall hung heater. It is not functioning. The blue mains on/off indicator + fault diagnostic light is on and blue. Not flashing. The heater occasionally comes on for some seconds then goes off again. Turning on a hot tap does not cause the heater to ignite and the burner indicator light is off. Can we correct the fault ourselves, please?

Based on the central heating starting when there is demand, this confirms the boiler is working as expected, and suggests the water in your megaflow is not demanding heat, which points to the programmer. By pressing the boost function this should start the boiler up and heat the water in the cylinder, after 20 minutes water should be warm, and after 45 minutes the water should be hot from the taps.
