5. Operating Instructions
5.1 Making Espresso Coffee (1-4 Cups)

The SOWTECH Espresso Machine features a simple one-button operation for ease of use.
- Fill Water Reservoir: Open the water tank lid and fill the reservoir with fresh, cold water according to the desired number of cups (1-4 cups, 240ml for 4 cups). Do not exceed the MAX line.
- Add Coffee Grounds: Place the filter into the filter holder. Add medium ground coffee (recommended >0.5mm) to the filter. Do not use fine ground coffee as it may clog the machine.

- Serve: Carefully remove the carafe and serve your fresh espresso.
5.2 Frothing Milk for Cappuccino/Latte

The powerful steam wand allows you to create silky, dense milk foam for your favorite milk-based coffee drinks.
- Prepare Milk: Fill a metal frothing pitcher with cold whole milk. For best results, use cold whole milk.
- Heat Machine: Ensure the water reservoir has enough water. Turn the control knob to the "Steam" position. The machine will begin to heat up to generate steam. Wait until the indicator light illuminates, indicating it's ready.
- Purge Steam Wand: Before frothing, briefly open the steam valve to release any condensed water. Close the valve immediately.
- Froth Milk: Immerse the steam wand tip just below the surface of the milk. Slowly open the steam valve. Move the pitcher up and down to incorporate air and create foam. Once desired foam consistency is achieved, close the steam valve.
- Clean Steam Wand: Immediately after frothing, wipe the steam wand with a damp cloth to remove any milk residue. Briefly open the steam valve again to clear any milk from inside the wand.
6. Cleaning and Maintenance
Regular cleaning ensures optimal performance and extends the life of your SOWTECH Espresso Coffee Machine.
- Daily Cleaning:
- After each use, unplug the machine and allow it to cool.

- Empty and clean the carafe.
- Remove and empty the drip tray. Wash it with warm, soapy water.
- Wipe the exterior of the machine with a soft, damp cloth.
- Steam Wand Cleaning: Always clean the steam wand immediately after frothing milk to prevent milk residue from drying and clogging. Wipe with a damp cloth and briefly purge steam.
- Descaling: Depending on water hardness, descaling should be performed every 2-3 months.
- Prepare a descaling solution according to the descaler manufacturer's instructions (or use a mixture of white vinegar and water).
- Fill the water reservoir with the descaling solution.
- Place an empty carafe under the filter holder.
- Turn the machine on and run half of the solution through the brew cycle.
- Turn the control knob to "Steam" and run the remaining solution through the steam wand.
