Hi, Could you possibly be experiencing a problem with the steam boiler thermostat? If it is tripping, then the steam boiler and light will lose power and the pStat will never get any pressure build up, so the brew boiler wont get power. You could test the thermostat by measuring voltage across it during heating up. It should remain at around 0VAC the whole time. If you notice any appreciable voltage across it, then it is going open circuit and stopping your boiler from receiving power.
