Steam boiler loud pop sounds

When the machine is turned on from cold, I can hear the water heating in the boiler. As the steam is developing, at one point, I get a very loud pow sound like a release of pressure. That was not happening every time the machine was starting up. Yesterday, it was like it was continuously doing it. I turned the machine off. Any help would be appreciated.

If you press the Boiler button to disable the Steam Boiler as soon as you start the machine, does it still do it? When you hear the noise it there any water or steam that comes out of the pressure relief valve?

No it doesn’t. I am not sure what the pressure relief valve looks like. Is there a diagram that identifies major parts! If so, where can I get it?
