Setup
- Unpacking: Carefully remove the coffee machine and all accessories from the packaging. Retain packaging for future transport or storage.
- Placement: Place the machine on a stable, flat, heat-resistant surface, away from water sources and direct sunlight. Ensure adequate ventilation around the unit.
- Initial Cleaning: Before first use, clean the water tank, drip tray, and cup tray with warm soapy water. Rinse thoroughly and dry.
- Fill Water Tank: Remove the water tank from the machine. Fill it with fresh, cold drinking water up to the MAX line. Do not exceed the MAX line. Reattach the water tank securely to the machine.
- First Rinse Cycle: Place a large cup or container under the coffee outlet. Plug the machine into a grounded electrical outlet. The indicator light will illuminate. Press the brew button to run a cycle without a capsule. This primes the pump and cleans the internal system. Repeat this process 2-3 times.
- Preheating: After the rinse cycle, the machine will preheat. The indicator light will change to indicate it's ready for brewing.
Operating Instructions
Brewing Coffee
- Ensure Water: Check that the water tank has sufficient water. Refill if necessary.
- Power On: Plug in the machine. The indicator light will show the machine is heating up. Wait until the light indicates readiness (e.g., solid green or stops blinking).
- Insert Capsule: Lift the brewing lever to open the capsule compartment. Insert one Nespresso-compatible capsule into the compartment. Close the lever firmly until it clicks into place.
- Place Cup: Place your desired coffee cup on the cup tray, directly under the coffee outlet.
- Start Brewing: Press the brew button. The machine will start extracting coffee. The 20-bar pressure pump ensures optimal flavor extraction.
- Stop Brewing: The machine will automatically stop brewing after a preset volume. You can also press the button again to manually stop the flow if you prefer a shorter or longer coffee.

Daily Cleaning
