The full automatic electronic model has a touchpad that remembers how much water to dose through the grouphead for espresso coffee and also one for the hot water dispernser. In addition, the star button, which is used for programming the other buttons, can be utilized as a semi-automatic model where the user starts and stops the water through the espresso coffee grind by engaging/disengaging the star button. For the first few weeks, we recommend using this model as a semi-automatic until you find the right grind, the right tamp, and the right amount of espresso coffee in the basket (a.k.a. dose). Once these parameters are set, we then recommend programming the four coffee dosage buttons. The hot water dosage button can be programmed for dispensing hot water from the water wand. However, we recommend that you do not program more than 4 ounces of hot water as the hot water can exit the boiler faster than the pump can replenish the water in the boiler. If the water level gets too low in the internal boiler, it can damage the heating element.

The dosage buttons must be programmed with espresso coffee in the filter basket and with the handle locked into the grouphead. Programmng should not occur with water only. Programming is accomplished by holding the star button for 5 seconds (small light will flash), and then immediately selecting the dosage button you want to program. Once the desired amount of espresso coffee is dispensed, you press the same dosage button to stop the dispensing. Wait 30 seconds to allow amount of espresso coffee dispensed to be saved into memory. The machine is ready to be used or have another dosage button programmed.

Please note that if you change the grind setting to a finer grind, it is possible that the dosage dispensed could lessen, especially if the finer grind causes the internal over pressure valve to open sooner.
