Initial Setup and Priming
Before first use, ensure the machine is properly set up and primed to guarantee optimal performance and coffee quality.
Water Tank and Filter Preparation
The machine features an 85oz (2.5L) removable water tank. Always use filtered water for best results. Condition the water filter by soaking it for 5 minutes before installation.

Priming the Machine
To prime the machine, ensure it is plugged in but powered off. Fill the plunger with water and tip it upside down. Press and hold the temperature button for 3 seconds until the lights turn on. Press the start button. Insert the plunger into the hole where the water tank usually sits and pump water until water dispenses from the front. Press the start button again to stop. Then, fill the water tank and install the conditioned water filter.

Operating Instructions
Bean Hopper and Portafilter
Fill the removable bean hopper with your preferred coffee beans. Lock the hopper into place. Select the appropriate portafilter basket (single or double shot, single or double wall) from the storage area under the drip tray. For lattes, a single wall, two-shot basket is recommended for better control.

Grinding and Tamping
Insert the portafilter into the grinder. Adjust the grind size and grind amount using the control knobs. For a two-shot latte, an ideal grind amount setting is available. After grinding, place the portafilter on a flat surface and use the tamper to apply even pressure, aiming for the ideal tamp level indicated. Lock the portafilter into the brew head.

Brewing Espresso
Use the brew mode buttons to select espresso, desired shot amount (1 or 2), and temperature. Press the start button to begin brewing. Monitor the pressure gauge to ensure extraction is within the ideal espresso range. If not, adjust grind size, grind amount, tamping pressure, or switch to a double wall basket.

Frothing Milk
Toggle the mode button to steam. Fill the milk pitcher to just under halfway with cold milk. Angle the steam wand into the top of the milk, near the side of the pitcher. Press start to begin frothing. Remove your hand when the pitcher feels hot to the touch, indicating the milk is frothed. Pour the frothed milk over your espresso to create lattes or cappuccinos.

Troubleshooting
Espresso Extraction Issues
- Problem: Espresso extracts too quickly or too slowly, or pressure gauge is outside the ideal range.
- Solution: Adjust grind size (finer for slower extraction, coarser for faster), modify grind amount, change tamping pressure, or switch to a double wall basket for more resistance.
Machine Not Heating
- Problem: Machine does not heat up or lights do not illuminate.
- Solution: Ensure the machine is properly plugged into a working power outlet. Check the water tank level.
Water Leaks
- Problem: Water leaking from the machine.
- Solution: Check that the water tank is correctly seated and not overfilled. Ensure the portafilter is securely locked into the brew head. If leaks persist, contact customer support.
