The Sencor SES 1721BK is a portafilter coffee machine designed for home use. To get started, ensure the machine is placed on a flat, stable surface with 15 cm of clearance.

Description of the Coffee Machine
The machine consists of a cup warming plate, control panel, brew head, portafilter, drip tray, water tank, steam/hot water dispenser control, and steam nozzle. The control panel includes a power button, temperature indicator, coffee brewing button, and steam dispenser button.



Before First Use
- Remove all promotional labels and packaging.
- Place the machine on a flat, dry surface with at least 35 cm of space above and 15 cm on the sides.
- Rinse the water tank, drip tray, portafilter, and baskets with clean water and a small amount of neutral detergent.
- Wipe the outer surface with a damp sponge and dry thoroughly.
Preparing Before Use
- Drip Tray: Ensure it is correctly installed. Empty it when the fullness indicator (float) rises.
- Water Tank: Fill with cold drinking water up to the max mark. Do not use hot water or milk.
- Coffee Preparation: Use the appropriate basket (1-cup or 2-cup). Fill with ground coffee, spread evenly, and tamp with the flat end of the measuring scoop. Clean the edges of the basket before inserting into the brew head.
- Portafilter Installation: Align the portafilter with the brew head, insert, and turn to the right to lock.
Using the Coffee Machine
Turning on and Preheating: Press the power button. The light turns red. When the coffee brewing button light turns green, the machine is ready. Perform a rinse cycle by running water through the spout and steam nozzle before the first coffee preparation.
Coffee Preparation
- Insert the basket into the portafilter and fill with ground coffee.
- Attach the portafilter to the brew head.
- Place a cup under the portafilter.
- Press the coffee brewing button.
- For the 1-cup basket, stop the dispensing manually by pressing the button again. For the 2-cup basket, dispensing stops automatically.
Dispensing Hot Water
- Place a cup under the steam nozzle.
- Press the coffee brewing button.
- Turn the steam/hot water control to the hot water position.
- Once the desired amount is reached, press the button again and turn the control to OFF.
Milk Frothing
- Fill a container with cold semi-skimmed or whole milk (no more than 1/3 capacity).
- Press the steam button and wait for the light to indicate the boiler is ready.
- Turn the steam control to the steam position to purge excess water, then turn OFF.
- Insert the nozzle just below the milk surface and turn the control to the steam position.
- Hold the container tilted to create a swirling motion.
- Once frothed, turn the control to OFF and remove the container.
Cleaning and Maintenance
- After each use: Clean the portafilter, baskets, and steam nozzle.
- Drip Tray: Empty and wash regularly.
- Outer Case: Wipe with a damp cloth.
- Warning: Do not submerge the appliance in water. No components are dishwasher safe.
Descaling
Regular descaling is necessary to remove mineral deposits. Use a descaling agent suitable for espresso machines. Follow the instructions on the descaling agent packaging, run the solution through the brew head and steam nozzle, then rinse thoroughly with clean water.
Troubleshooting
If the machine does not turn on, check the power connection. If water leaks, empty the drip tray. If there is no steam, ensure the steam button light is green and the nozzle is clean. If the coffee smells acidic, perform a descaling cycle.
