Steam temperature

The desired steam temperature can be set in the menu item "Steam Temperature". The factory default
steam temperature is set at 128 °C (262,4 °F). The temperature can be increased up to 132 °C (269,6°F).
We recommend a lower steam temperature at first to familiarize yourself with foaming milk.

Preinfusion

The DRIVE offers various settings for preinfusion. In the menu item "Preinfusion", the values for
preinfusion can be switched on "ON" or off "OFF" and changed.
Some coffee roasts, particularly lighter roasts, are prone to something called channeling. Besides
properly preparing your coffee grounds (grinding, distribution, tamping), it can be helpful to use pre-
infusion in such cases. Pre-infusion involves fully saturating the coffee grounds with water before
continuing with high-pressure extraction.
There are various options for preinfusion. The „Flow Control" (chapter 7.2) allows you to use an individual
preinfusion without interrupting the pump. If this preinfusion is not sufficient, it is also possible to
influence the preinfusion actively (with pump activity) and/or passively (without pump activity).
