Cleaning an espresso or coffee machine is fairly easy. Like most appliances in your kitchen, you need to wipe the dust off and clean it well after you use it. Also, since Cuisinart espresso machines have metal parts, you should decalcify the unit after every 3 months of daily use to remove any calcium deposits that have formed in your unit. The steps below show you the proper way to clean and decalcify your Cuisinart espresso machine.
Turn off your espresso machine and unplug it before cleaning. Wipe the outside of the machine with a damp cloth and dry. Remove the drip tray and wash in warm, soapy water.
Rinse the stainless steel filter and portafilter holder immediately after each use.
Run water through the unit once a week with the portafilter in place but without coffee to clean out any coffee particles. Wipe the inside of the brew head to remove coffee particles.
Clean the steam wand after steaming milk. Point the wand into the drip tray and turn the function knob to "hot water" momentarily to flush any remaining milk. Wipe the wand with a damp cloth.
Fill the reservoir almost to the top with 1/3 white vinegar and 2/3 water when decalcifying. Pour in the decalcifying agent, then set the function knob to "off" and set the power to "on". Put a large container under the brew head. When the heating light switches off, set the function knob to "espresso" and run half the solution through the machine. Then, set the function knob to "steam" and run the remainder through the steam wand. Finally, fill the reservoir with fresh, cold water and run that through to rinse your machine.
