Professional espresso machines have more parts and controls than home machines. They include a head group for extraction, portafilter to hold coffee grounds, extraction buttons, steam wand for milk, steam knob to control steaming time, hot water pipe, and indicators for pressure and temperature. Learning the purpose of each part is important before operating a professional espresso machine to pull shots and steam milk correctly.
