Dream UP V2 Espresso Machine Finish: Polished Aluminum Simple to use controls - Flip on the center power switch to begin heating up the boiler. Two more professional grade rocker switches now let you control the steam function (far left) and the coffee brew control (far right). A series of indicator lights inform you when the machine is powered up, and when it is at the proper temperature for either brewing espresso or frothing milk. Quality brewing group - The grouphead is made of chrome plated brass. Designed after Ascaso's commercial espresso machines, the Dream UP group head evenly distributes heat and reduces hotspots for more temperature consistent espresso. It has also been designed to evenly distribute water across the coffee grounds for a better extraction. Three way solenoid valve - As soon as the coffee switch is turned off, the three way solenoid valve relieves the pressure built up in the grouphead. The pressurized water is reverted to the water reservoir, and this feature allows back-to-back espresso extractions without having to wait for the portafilter handle to lose pressure by itself. Stainless-lined aluminum thermoblock - After years of testing, the aluminum thermoblock with internal stainless steel lining of the water passage ways work remarkably well. Frothing tip for perfect foam - Like magic, the wand will make perfect foam. In an instant, the steam wand converts the milk in your 12 or 20 oz. frothing pitcher to lovely foam for lattes and cappuccinos. Mounted on a swivel joint, the stainless steel steam wand conveniently swings aside and clean up is a snap. When frothing milk with this machine, please make sure to have the little hole in the frothing adapter positioned at the top level of the milk. Doing it this way will help aerate the milk froth.
