NASA Electric NS-536 Espresso Machine Components & First-Time Use Guide

Components and Accessories

The NASA Electric NS-536 Espresso Machine is equipped with several essential components designed for efficient coffee preparation. Its stainless steel body provides durability, easy cleaning, and a modern appearance. The 1.5-liter removable water tank allows convenient filling and maintenance.
The powerful 20-bar pressure pump ensures high-quality espresso extraction with a rich flavor similar to professional coffee shops. The steam nozzle enables users to prepare smooth milk foam for cappuccino and latte.
The machine includes a portafilter with single and double shot filters, allowing preparation of one or two cups of espresso. The removable drip tray makes cleaning easier, while the included coffee scoop and tamper help measure and compress coffee powder properly for better extraction.

First-Time Use Tips

Before using the NASA Electric NS-536 Espresso Machine for the first time, wash all removable parts, including the water tank, lid, coffee scoop, tamper, filter, and filter holder, with warm water and mild dishwashing liquid.
Clean the body and drip tray with a soft damp cloth, then dry all parts completely. Turn off the steam knob, fill the water tank with fresh filtered water, and turn on the machine.
Wait until the indicator lights turn on and the machine reaches the required temperature. Finally, run one extraction cycle without coffee in the portafilter to clean and rinse the internal pathways before making your first espresso.

How to Use the NASA Electric NS-536 Espresso Machine

Fill the water tank with fresh, filtered water, place the machine on a flat surface, and turn it on. The preheating process takes approximately 2 minutes. Always switch off the machine before removing or refilling the water tank.
Rotate the portafilter to the left to remove it from the group head. Fill it with the desired amount of ground coffee, then use the tamper to press the coffee evenly and create a flat surface. Lock the portafilter back into the group head by turning it to the right.
Ensure the steam control is set to the OFF (0) position. Place a cup beneath the coffee outlet, press the power button, and select either the single-shot or double-shot button to begin extraction.
Once brewing is complete, remove the portafilter and discard the used coffee grounds before preparing the next cup.

How to Prepare Espresso

To make a standard espresso, add 7–9 g of ground coffee into the single-shot filter. For a double espresso, use 14–18 g of coffee in the double-shot filter.
After filling the portafilter, compress the coffee evenly with the tamper to ensure balanced extraction and a rich flavor. Lock the portafilter into the group head, then press the Single Shot or Double Shot button to start brewing.
The final taste of your espresso depends on several factors, including the coffee bean type, roast level, freshness, grind size, coffee dose, and tamping pressure. Adjust these variables to achieve your preferred flavor.

How to Froth Milk

Pour cold full-fat milk into a stainless-steel milk pitcher. Press the Steam button and wait until the machine reaches the required temperature. If the machine is still heating, the steam indicator will flash; once ready, it will remain steady.
Briefly open the steam control knob to release condensed water from the steam nozzle, then close it again. Place the nozzle just below the milk surface near the edge of the pitcher and allow the milk to swirl to create fine foam.
After sufficient foam has formed, lower the steam nozzle deeper into the milk to heat it. When finished, gently tap the pitcher on a flat surface to remove large bubbles and create smooth microfoam.
Finally, wipe the steam nozzle clean and activate steam for a few seconds to remove any remaining milk residue.

Espresso Machine Pressure Gauge Guide

The pressure gauge on the NASA Electric NS-536 Espresso Machine indicates the brewing pressure during espresso extraction.

1. Normal Range: If the needle stays within the recommended range, the espresso is extracted correctly, producing a rich and balanced flavor.
2. Low Pressure: If the needle is below the ideal range, water flows too quickly through the coffee, resulting in weak and under-extracted espresso. This is usually caused by a coarse grind, insufficient coffee dose, or light tamping.
3. High Pressure: If the needle rises above the recommended range, water passes too slowly through the coffee, leading to over-extracted, bitter espresso. This is commonly caused by a fine grind, excessive coffee dose, or overly firm tamping.

Cleaning and Maintenance Guide for the NASA Electric NS-536 Espresso Machine

Regular cleaning helps maintain coffee quality and extends the lifespan of your NASA Electric NS-536 Espresso Machine.
After each use, rinse the portafilter and filter baskets with clean water and remove all used coffee grounds. Wipe the steam nozzle immediately after frothing milk to prevent milk residue from drying inside the nozzle. Empty and wash the drip tray regularly to keep the machine clean.
Clean the exterior of the machine with a soft, damp cloth and avoid washing the body directly with water. To maintain optimal performance, descale the internal water system periodically using a suitable espresso machine descaling solution.
