To descale your DeLonghi ECZ351BG, fill the water tank with a descaling solution and water as per the instructions on the descaling product. Place a container under the steam nozzle and run the solution through the machine as if you are brewing coffee, then rinse thoroughly with clean water.
If your machine is not producing steam, ensure that the steam knob is fully open and that the water tank is filled. Check for any blockages in the steam nozzle and clean them if necessary.
For the DeLonghi ECZ351BG, use a fine grind size similar to table salt. This ensures optimal extraction and flavor. Adjust the grind size if the coffee is too bitter or too watery.
To improve crema, use freshly roasted coffee beans and ensure they are finely ground. Preheat your cup, and ensure the machine has reached the correct temperature before brewing.
If coffee is brewing too slowly, the grind may be too fine or the portafilter is overpacked. Adjust the grind size to be slightly coarser and ensure the coffee is tamped evenly but not too firmly.
Clean the DeLonghi ECZ351BG after each use by rinsing the portafilter and wiping down the steam wand. Perform a deeper clean, including descaling, every 2-3 months, depending on usage frequency.
Watery espresso may result from a coarse grind, insufficient coffee in the portafilter, or the coffee not being tamped evenly. Ensure you use a fine grind and pack the coffee properly.
Yes, you can use pre-ground coffee; however, for the best results, use a grind specifically for espresso. Adjust the tamping pressure and amount according to the strength you prefer.
To froth milk, fill a jug with cold milk up to a third full. Submerge the steam wand just below the surface and open the steam valve. Move the jug down slowly to introduce air, then submerge the wand deeper to heat the milk.
Check that the water tank is properly seated and the drip tray is not overflowing. Inspect the seals for wear and replace if necessary. Ensure all removable parts are correctly assembled.
