So that your espresso machine will last, TheCoffeeBrewers recommends that you use distilled water, and not tap water in your espresso machine.
Semiautomatic Espresso Machines are pump-driven espresso machines with a rocker switch connected to the pump. You turn the pump on to start the extraction, and then you turn the pump off to stop the extraction. These are the least expensive of the espresso machines. Semiautomatic espresso machines also have steam wands that you can use to froth or steam milk for cappuccino and latte.
