Thank you for your response. I confirm that the steam light comes on approximately 1-2 minutes after the steam switch is pressed, which is as it always been since day one. I then open the valve and eject a bit of water for 2 seconds before I start to steam my milk (with only a 60-70% efficiency which is my problem). My understanding is that when I press the steam switch, the boiler starts heating the water to transform it into steam. Somehow I feel the water may not being all turned into steam (or less than it should be). But I’m not sure I understand what the thermostat input is and what output it gives to the boiler. Like what is the trigger for the steam thermostat to '''stop''' boiling the water? Can it be as simple as let’s say 120DegC (250 DegF)?[br] [br] I also thought a thermostat is either Go or NoGo, that it could not be partially defective, as if it would command to stop boiling at a lower temperature point than designed. Do you confirm that? My goal is to pinpoint the problem and if the thermostat is Go, then I can dig for something else.[br] [br] Looking forward to a reply :) Derek.
