If your Gaggia Brera is producing cold espresso shots or coffee, or if you feel as though your Brera's coffee is not hot enough, review the following instructions.
Make sure you are using a preheated cup. Ceramic cups will sap a lot of heat from the shot resulting in a colder shot. Preheating the cups using the machine's hot water function is suggested, or you can brew into a paper, styrofoam, or other well insulated cup. If your machine utilizes a cup warming function, you can use it to preheat the cups. Alternatively you can use the machine's hot water function to fill the cup with hot water before pulling a shot to preheat it. If the shots are completely cold, then the brew thermostat is broken and the machine will require a repair.
