Customizing the “my coffee” quantity
The appliance is set by default to automatically deliver 1 fl oz./ 30 ml of “my coffee”.
To modify this quantity, proceed as follows:
1. Place a cup under the coffee spouts (fig. 11).
2. Turn the selection knob until “MY COFFEE” is displayed.
3. Keep the button (fig. 8) pressed until the message “1 MY COFFEE Program quantity” is displayed and coffee delivery begins. Release the button.
4. As soon as the coffee in the cup reaches the required level, press the button (fig. 8)again.
The quantity of coffee in the cup has now been programmed.11-01-13 05:01PM
I have done some checking and your method will only get to a maximum of 6 oz's. However, if you select the 2 cup mode the machine appears to double only the liquid. It does not grind any additional coffee. So if you selct any of the presets buttons the default liquid value gets multiplied by two. So in my instance I selct the extra long coffee, which has a default value of 4 oz and then by pressing the 2 cups button I get a 8 oz coffee.
thank you for your help.11-01-13 05:01PM
