Operating Instructions
1. Grinding Coffee Beans
- Select Grind Setting: The integrated conical burr grinder offers 30 precise grind settings. Adjust the dial on the bean hopper to your desired fineness.
- Fine (1-5 settings): For slower extraction, typically for espresso.
- Medium (6-15 settings): For balanced extraction.
- Coarse (16-30 settings): For faster extraction, suitable for other coffee types.

- Prepare Portafilter: Insert the desired filter basket (single or double) into the 58MM portafilter. Attach the dosing ring to the portafilter to minimize mess during grinding.
- Grind: Place the portafilter into the grinding cradle. The machine will automatically grind the selected amount of coffee directly into the portafilter.
- Tamp: After grinding, remove the portafilter and dosing ring. Use the provided tamper to evenly press the coffee grounds to the indicated level.
2. Brewing Espresso
- Insert Portafilter: Lock the portafilter firmly into the grouphead of the machine.

3. Milk Frothing (Steam Wand)
- Prepare Milk: Fill the milk frother pitcher with cold milk.
- Activate Steam: Press the steam button on the control panel. Wait for the machine to reach optimal steaming temperature (indicator light will stabilize).
- Froth Milk: Submerge the steam wand tip just below the surface of the milk. Turn the steam knob to release steam. Move the pitcher up and down to create silky, smooth micro-foam.

- Clean Wand: After frothing, wipe the steam wand immediately with a damp cloth to prevent milk residue from drying. Briefly purge the wand to clear any internal milk.
4. Cup Warming
The top surface of the machine acts as a cup warming tray. Place your espresso cups here to pre-heat them, which helps maintain the temperature of your coffee after brewing.

Troubleshooting
If you encounter issues with your Neretva PE3650U, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine lights are blinking continuously, unable to brew. | Machine may be in an error state or not fully heated. | Turn the machine off, wait a few minutes, then turn it back on. Allow sufficient time for pre-heating (lights should stop blinking when ready). If the issue persists, contact customer support. |
| No coffee dispenses or flow is very slow. | Coffee grounds too fine, too much coffee in portafilter, or portafilter tamped too hard. Machine may need descaling. | Adjust grind setting to be slightly coarser. Reduce coffee dose or tamp with less pressure. Perform a descaling cycle. |
| Coffee dispenses too quickly, weak espresso. | Coffee grounds too coarse, too little coffee, or not tamped enough. | Adjust grind setting to be finer. Increase coffee dose or tamp with more pressure. |
| Steam wand not producing steam or milk not frothing. | Steam wand clogged, not at correct temperature, or insufficient water. | Ensure the steam button is activated and the machine is fully heated. Clean the steam wand thoroughly. Check water tank level. |
| Water leaking from machine. | Water tank not seated correctly, or internal seal issue. | Ensure the water tank is properly installed. If leaking persists, discontinue use and contact customer support. |
