Problem Possible Cause Remedy The coffee is not hot The cups have not been preheated. Heat the cups by rinsing them with hot water. The coffee is not creamy enough. The coffee runs out too slowly or in drips. The coffee runs out too quickly. The coffee does not run out of one or both of the spouts. The coffee comes out around the service door instead of from the spouts. Water comes out of the spouts instead of coffee. The milk does not come out of the milk spout. The milk is not wellfrothed. The milk contains large bubbles or spurts out of the milk spout. The brewing unit has cooled down because 2-3 minutes have elapsed since the last coffee was made. The set temperature is not high enough. The coffee is ground too coarsely. The blend of coffee is unsuitable. The coffee is ground too finely. The coffee is ground too coarsely. The spouts are blocked. The holes in the spouts are clogged with dry coffee powder. The coffee feed inside the service door is blocked. Ground coffee is blocking the funnel. The intake tube is not inserted or is inserted incorrectly. The milk container lid is dirty. The milk pointer is incorrectly positioned. The milk is not cold enough or is not 2%. The milk frother pointer is incorrectly adjusted. The milk container lid is dirty. Before making coffee, heat the brewing unit by selecting the Rinse function from the menu. Change the set temperature. See Coffee Temperature in the Settings section. Turn the grinding coarseness adjustment knob one click counterclockwise toward the number 1 while the coffee mill is in operation. See the djusting the Coffee Grinder section. Use a blend of coffee specifically for espresso coffee machines. Turn the grinding coarseness adjustment knob one click clockwise toward the number 7 while the coffee mill is in operation. Continue one click at a time until coffee runoff is satisfactory. Results are only visible after making 2 cups of coffee. See the djusting the Coffee Grinder section.

IMPORTNT: Electrostatic Discharge (ESD) Sensitive Electronics ESD problems are present everywhere. Most people begin to feel an ESD discharge at approximately 3000V. It takes as little as 10V to destroy, damage, or weaken the main control assembly. The new main control assembly may appear to work well after repair is finished, but a malfunction may occur at a later date due to ESD stress. Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the appliance -OR- Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance. Before removing the part from its package, touch the anti-static bag to a green ground connection point or unpainted metal in the appliance. void touching electronic parts or terminal contacts; handle electronic control assembly by edges only. When repackaging main control assembly in anti-static bag, observe above instructions.
