Your Guide to Espresso Machine Gauges Understanding the Two Critical Gauges Most professional espresso machines have two separate pressure gauges. It is crucial to know which one you are replacing. The Pump Pressure Gauge (or Brew Gauge): This gauge shows the pressure of the water as it is being forced through the coffee puck by the pump. It typically reads from 0 to 16 bar. This is the gauge you watch during the shot to ensure you are brewing at the correct pressure (usually around 9 bar). The Boiler Pressure Gauge (or Steam Gauge): This gauge shows the steam pressure inside the machine's boiler. It typically reads from 0 to 3 bar. This is the gauge you monitor to ensure your machine is at the correct temperature and has sufficient steam power for frothing milk. Why Replace a Gauge? Over time, gauges can fail, become inaccurate, or get damaged. A faulty gauge can lead to inconsistent espresso, poor steam performance, or a failure to diagnose other problems within your machine. Replacing a broken gauge is a critical maintenance task. Choosing the Right Part When selecting a replacement, ensure you match the thread size and diameter of your old gauge.
