Button on the boiler?
Slow flash or fast flash?

Can you confirm the pressure on the gauge?

between 1&2
Plumber: Andrew Smith, Engineer replied 9 months ago
Ok, pressure is good.
Is the light flashing slow or fast?
Both mean different things

Slow
Plumber: Andrew Smith, Engineer replied 8 months ago

Ok, so you reset the boiler and it starts making noises and then 5 seconds later you get the slow flash?

If so then it is just failing to light, perhaps a service and clean of the electrodes will cure this.
