This morning the same routine: temp stabilizes at 200, brew pressure gauge reads 10 bars. I pull one shot (again a long extraction time) and the brew pressure gauge falls to and stays at 0 the temp starts to climb. While this is happening I hear a gurgling noise from inside the machine.
Sounds almost like 2 problems, an overpressure valve that sticks open and a defective or badly set up PID. Can you go through all the PID settings and make sure they are the same as factory recommended.
I keep trying to figure out if a loose wire or a couple of swapped wires would cause this, but I don't really see how.
When you pull the second shot with a blind disk and get no pressure is the water returning to the tank? Does water come out of the short hose or do you notice the pressure on the steam boiler changing? Is the water in the steam boiler hot?
