During the initial use, a rinsing cycle is required to properly clean the water circuit, brewing system, and hot water/steam wand.
Before powering on, ensure the coffee bean container and water tank are properly installed, and the hot water/steam wand points at the drip tray.
When you power on your espresso machine, all the indicators and buttons will flash, indicating the start of the rinsing cycle. Pressing any button will start the rinsing. Water will be dispensed from the brewing spout and the hot water/steam wand until rinsing is done. Then, the light of the Power On button will flash, indicating the machine is heating up.
When the flashing stops and all the brewing buttons light up, the machine is ready for use.
