Complete Guide to Using the NASA Electric NS-540 Espresso Machine
To achieve the best coffee flavor and optimal performance, follow these steps carefully. Before the first use, run clean water through the brewing system without coffee to rinse the internal pathways. Install all components, including the drip tray and containers, in their correct positions.
Remove the water and milk tanks, fill them with fresh filtered water and cold milk, and make sure the liquid level does not exceed the maximum indicator. Reinstall the tanks, lock the milk tank properly, and connect the machine to the power supply. Touch the power button to start the heating process. When the indicators remain steady, the machine is ready for use.
For better temperature stability, install the portafilter and filter basket without coffee and run hot water through them to preheat the brewing parts. Then select the suitable basket, add the recommended amount of espresso powder, and tamp it evenly. Lock the portafilter into place and select the desired function to begin extraction.
To manually adjust the coffee volume, press and hold the selected button for a few seconds and stop the process whenever the desired amount is reached.
For milk-based drinks, fill the milk tank with cold milk, lock it securely, and select the cappuccino or latte function. For independent milk frothing, double-tap the cappuccino icon to activate the foam-making mode.
Through the settings menu, you can adjust the temperature across three levels and save customized beverage volumes. To restore factory settings, press and hold the temperature adjustment button and double espresso button simultaneously for a few seconds.
