Espresso Machine, 44 Grind Settings, Temp Control, AMZCHEF

Air may be trapped in the water line, especially during first use. For best results, use cold whole milk with at least 3% fat at 41–50°F (5–10°C), then insert the steam wand and turn the steam knob to start frothing. Turn the steam knob briefly to purge water, then wait until steady steam appears before frothing milk. Check whether the water tank, drip tray, and portafilter are installed correctly. Empty the tray regularly and make sure the portafilter is firmly locked before brewing. Fill and reinstall the water tank, then open the steam knob and run the hot water function until water flows steadily. Turn off the machine and clean the bean hopper and grinder outlet.
