The temperature of the coffee is not good; the coffee is not hot enough or too hot.
If the coffee is not hot enough you may not have preheated the cups. Preheat the cups on the cup warmer tray. You can also preheat the cups by putting them under the coffee spout before the appliance flushes. The hot water from the flushing cycle will preheat the cups.
If your coffee is not hot enough the system/brewing unit might be too cold. Heat the brewing unit by flushing the appliance before you brew coffee (use the ‘flushing’ option in the menu).
You can adjust the coffee temperature in the menu. Press the MENU button and scroll with the arrow buttons to ‘SET TEMPERATURE?’, here you can choose between low, medium and high.
