• Ensure all the button surrounds on the control panel are illuminated, indicating the machi-
ne has reached the correct temperature for brewing, and is ready for use.
• Ensure the drip tray and portafilter are in place.
• Place one or two pre-warmed cups beneath the portafilter outlet.
note: pre-Brew funcTion: When a preset shot size on the front, right hand side of
the machine is selected, the machine will pump water momentarily, followed by a pause then
continue to pump the water through to the grounds in the portafilter. The ground coffee is
moistened by a small amount of water before full extraction. This expands the grinds, resul-
ting in greater pressure build-up to extract all the oils and full flavor from the ground beans.
