Answers:    This question have been answered several times this week, soon bring up to date when it goes cold.lol. If the spout has a thermostat on (has numbers on it) remove the cranium, (either knurled ring or clamp with a screw beneath the head), tap the pin beneath the head a few times untill the steam comes through, re-fit the head.
Check that the valve BOTH ends are open.
