Definitely worth checking that the boiler isn’t over pressure. But a slow consistent leak is certainly likely to be a failed safety valve. When the safety valve goes off it tends not to be subtle.
I purchased my brewtus IV a little over a year ago, and experienced the same issue, I’m the third owner of this 10 year old machine, no surprise that rubber parts would be starting to fail. There was a slow leak from the safety valve, barely audible, but it would make cups on the warming tray wet, and would cause the fill valve and the pump to kick On to refill the boiler ever 10 minutes or so. Generally speaking I don’t recommend messing with safety valves on steam boilers. For the price it’s better to just replace it and know that everything is working as intended. Additionally manufacturers tend to make them hard to service, they are often somehow sealed with a river or safety wire once calibrated. I will say the one thing maybe worth trying is to intentionally open the safety valve. If you feel comfortable with it, you could try burping it a few times to see if it doesn’t reseat. You’ll need to pull up on the little shaft sticking out of the top of the valve while the boiler has a little pressure on it. Make sure the machine is unplugged, and Don’t do it while the machine is at operating pressure. I’d recommend like .2-.4 bar. Use long pliers/channel locks to pull the release, and shield your hands with a dry towel or high temp gloves If that fixes it, great! If not just replace it with a new one. Best of luck!.
