FAQs
Dual-boiler and heat-exchanger designs are common in this category. Dual-boiler machines use separate boilers for brewing and steaming. Heat-exchanger machines pass brewing water through a separate pathway inside a steam boiler. Boiler design, heater output, and steam controls all contribute to a machine’s steaming characteristics.
A steam pressure gauge typically displays pressure inside the steam boiler, usually in bars. It does not directly measure pressure at the steam tip. Check your machine’s manual for its normal operating range, and distinguish the steam gauge from any separate brew-pressure gauge.
Let the machine reach its recommended operating temperature, then briefly purge the steam wand into the drip tray to clear collected condensation. Start with cold milk in a clean steaming pitcher, and position the steam tip before opening the steam valve. Follow your machine’s instructions for operating its steam controls.
If your machine offers variable steam control, start with a manageable flow while you learn its response. Keep the steam tip just below the milk’s surface to introduce air, then lower it slightly and angle the pitcher to maintain a rolling motion. With high steam power, make small adjustments and monitor milk temperature closely.
After each use, wipe the wand with a dedicated damp cloth and briefly purge it according to the manufacturer’s instructions. For dried milk or blocked steam-tip holes, follow the manual’s cleaning procedure and use an approved milk-system cleaner when recommended. Remove or soak the steam tip only if the manufacturer permits it.
