How do I perform the initial setup of my K'Café Barista Bar?
Plug in your brewer and frother into an outlet, place a large mug (at least 10oz) on the drip tray, rinse and fill the water reservoir to the MAX FILL line, and replace it properly before powering on the machine. Then perform a cleansing brew by lifting and lowering the handle; press the 8oz button to start. The setup process is complete after pouring out the hot water.
