De-calcifying every 3 months
Remove the nozzle from the steam pipe. Fill carafe (2 oz. of white vinegar and 6 oz. cold water) and pour into the boiler. Close cap. Insert the filter holder with the basket into the machine and lock the filter holder. Place carafe without the lid under the filter holder on the drip tray. Place an empty cup under the steam pipe. Make sure the coffee/steam selector points to the cup symbol and the steam knob is closed. Turn the machine on and let the solution pass through the filter holder into the machine. With the carafe about ¾-filled, slide the selector to the steam symbol. Pass the solution through the steam pipe. Once steaming has stopped, close the steam knob. Repeat once or twice.
