First-Time Setup Guide for the NASA Electric NS-537 Espresso Machine

Before using the NASA Electric NS-537 Espresso Machine for the first time, proper cleaning and preparation are recommended to ensure the best performance.
Wash all removable parts, including the water tank, portafilter, filter baskets, and drip tray, with warm water and mild detergent, then dry them completely. Clean the machine body and drip tray with a soft, slightly damp cloth and make sure all parts are fully dry before assembly.
Fill the water tank with fresh, filtered water, turn on the machine, and wait until the indicator lights show that it is ready. Without adding coffee to the portafilter, run one water cycle through the machine to rinse the internal pathways.
Finally, activate the steam function and allow hot water to flow through the steam nozzle for approximately 8 seconds to complete the initial preparation process.

How to Use the NASA Electric NS-537 Espresso Machine

Follow these steps to prepare espresso with the NASA Electric NS-537 Espresso Machine:

1. Fill the water tank up to the MAX indicator line and turn on the machine. The preheating process will begin and takes approximately 2 minutes.
2. Remove the portafilter, place the suitable single or double-shot filter basket inside, and add the appropriate amount of coffee powder.
3. Use the tamper to evenly press and level the coffee grounds inside the filter basket.
4. Attach the portafilter to the group head and rotate it 45 degrees to the left until it locks securely in place. Then position a cup under the coffee outlet.
5. Press the single or double espresso button to start the extraction process.
6. After extraction is complete, remove the portafilter and empty the used coffee grounds.

By following these steps, the NS-537 provides a simple and efficient way to prepare rich and flavorful espresso at home.

How to Prepare Espresso with the NASA Electric NS-537

To prepare a standard espresso shot, add 7–9 grams of finely ground coffee into the single-shot filter basket. For a double espresso, use approximately 14–18 grams of coffee. After filling the portafilter, press the coffee evenly using the tamper to ensure balanced extraction and a smoother flavor.
Insert the portafilter into the group head and press the single or double shot button to start extraction. The final taste depends on several factors, including coffee bean type, roast level, freshness, grind size, coffee dose, and tamping pressure. Adjust these factors gradually to achieve your preferred flavor profile.

How to Froth Milk for Cappuccino and Latte

For smooth milk foam, pour an appropriate amount of cold full-fat milk into a metal milk pitcher. Press the steam icon and wait a few seconds. If the steam temperature is not ready, the steam icon will flash. Once preheating is complete, the icon will remain steady.
Slightly turn the steam knob counterclockwise to release condensed water from the steam nozzle, then close it again. Place the nozzle near the edge of the milk pitcher, just below the milk surface, and adjust the angle so the milk starts rotating. This movement creates fine and creamy foam.
After forming enough foam, move the nozzle deeper into the milk to heat it. Finally, tap the pitcher gently on a flat surface to remove large bubbles and create a smooth texture. After finishing, clean the steam nozzle by activating steam briefly to remove remaining milk residue.

Adjusting Single and Double Shot Volume

To customize the single-shot volume, press and hold the single-shot button for 3 seconds. The machine will beep once and start extraction. When the desired amount of espresso is reached, press the single-shot icon again. The machine will beep three times, confirming the new volume setting.
The same procedure can be used to adjust the double-shot volume. The extraction time can be set between 8 and 60 seconds, and the selected duration must remain within this range.
To restore factory settings, press and hold the single and double shot icons simultaneously for 3 seconds. The NS-537 will beep three times, and all icons (except the C icon) will flash five times, indicating that the default settings have been restored.
