Ariston Micro system boiler problem. The ignition was firing

Customer Question

Ariston Micro system boiler problem. The ignition was firing even after boiler lit, so replaced PCB and sensors. Now it works fine until mid afternoon everyday and then reverts to old problem of shutting down as electrode keeps firing after being lit. - But starts fine again the next morning. So now thinking it may be the programmer (Drayton Tempus 7) ??

If the boiler keeps ticking once the boiler is lit, then it does not know it is lit. Try cleaning the spark electrode - if that does not work then replace it and the lead.
