hi guys, went to carry out a service... went to high fire setting mode but nothing happened? Blue flashing light 5 times.. checked condensate not blocked.. flue good..
Reset the thermostat knob but nothing happened. Standing gas pressure 25mb to the gas valve..
When I put the heating on from the programmer the boiler fires up fine but I noticed the blue light still flashing but faster? I notice the heat exchanger was very hot to touch and making noises?
I'm new gas engineer so be gentle.lol
