Not sure 100% on my diagnosis of the problem, so let me explain what happened..
I extracted my espresso as normal, and afterwards the pump clicked on to fill the boiler (as if I had just purged it all through the hot water tap). After a while, the pressure needle flickered rapidly, and spiked up to about 3 bar, settling back down to 1 bar pretty quickly.
After that, the heat switched back on; there was no pressure. The steam wand only shot out water, and the needle was flickering as the pressure rose. I left the steam valve open to let any air escape, and eventually it did..
The same thing happened again a little while later, but after that, it was fine. Nothing particularly dangerous or noisy happened, just the strange behaviour of the pressure needle, and the complete lack of steam pressure.
It seems to be fine now. It has self-corrected. It was only serviced a month ago, so its not in a state of disrepair. It is a shared office machine though, so I dont personally oversee the technique of everyone who uses it to make sure theyre treating it well ;D
Before I used it, the tank was empty, so it may be possible that some air was pumped in. (Im not familiar enough with the inner workings to say that with any certainty.)
Does it sound like something I should be worried about, or should I just leave well enough alone, unless it happens again?
