Alba is a classic Isomac machine with great durability and high performances. The double gauge, placed on the strategic top position shows both boiler and pump pressure.

Important Information to Note: Pump Pressure Gauge should only be looked at when extracting espresso. At no other time should this gauge be viewed as it is meaningless 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 int he basket is not proper Green Light - While warming up, this green light remains off until the machine reaches proper steam pressure (not pump pressure). If will go 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 throughout the day and it will definitely go off while while extracting as cold water enters the heat exchanger to extract espresso In addition, 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 extract espresso or steam milk will whil in this range.
