Pump Pressure Gauge should only be looked at when extracting espresso. It provides no useful information at all other times. Second, If the gauge shows different results while extracting, this indicates that your coffee grind tamping, or amount of ground coffee in the basket is not ideal
Green Light - While warming up, this green light remains off until the machine reaches proper steam pressure (not pump pressure). If will go on and off alternately with the red light while it intermittently re-heats to maintain steam pressure. In other words, it will turn on and off through out the day and it will definitely go off while extracting as cold water enters the heat exchanger to extract espresso
Boiler Pressure Gauge - Once the machines heats up, this gauge will vary from 0.8 to 1.3 depending upon setting, and it will change throughout the day in this range. As long as the machine is fully heated, the machine extracts espresso or steam milk while in this range.
