So this is probably my third gregtech world in a new pack and with the new steam machines I keep on having this problem. Whenever I make steam machines they are acting weird. They stop working when there is steam in the system that they can use. I have to pick them up and replace them to work. I have looked on youtube and on these forums and no one seems to have this problem. I was watching Bevolj's series and I copied his setup for the machines and they still don't work. Can someone please help!
Steam machines have a steam vent on them. If the vent is blocked, they will stop working until they can vent.
You can reposition the vent with a wrench. Also note that the vent will hurt you if you are standing in front ooopf IIT when it vents.
