Pasted from old thread:
Problem of leaking still going on. But I was nicely told by my service folk not to expect Ye ol' Rocket to perform like a commercial.
I made three double extractions straight off. Then when I started to steam the milk the boiler pressure zeroed and water came out. In amongst this water appeared under the unit. i stopped and waited and the boiler pressuer increased and soon I was steaming the six cups of milk with no problems. I did not think that 3 double extractions would cool the water that much in an HX machine. And why the pressure stayed up until I opened the steam valve. The next double shot was okay and I steamed the milk as normal, then the next double was okay with no water puddling. My fear is that the solenoid that opens for the boiler top up stayed open for the brew so cold water was being pumped into the boiler. This might then open the boiler opv to release pressure and so water came out.
Going to experiment with slower extractions. Also if water comes out of the steam pipe again to see if the flow increases if I open the brew handle with a puck still in the group - which will point to a faulty solenoid. After an extraction I will vent some hot water to see if the water level is replenished as expected if not then the boiler is well over it correct level.
I use this machine for a coffee time for folk at my work
