The Nespresso, an espresso machine manufactured by the Nestle company, brews espresso strength coffee by using single-use capsules. This machine requires a regular cleaning each day after the last use to clean away any leftover coffee grounds or residue. One some days, depending on your water hardness or when you notice mineral deposit buildup, Nestle recommends cleaning the machine and then running it through the descaling process.
Pull out and remove the capsule from the unit.
Fill the water tank with fresh water and press the coffee cup graphic button to start a cycle. Run it through with just the water, no capsule, to clear out any coffee ground deposits. Keep a container or coffee cup on the drip tray to catch the water and empty the water from the cup once the cycle stops.
Turn the power switch to "Off." Wait for the unit to cool.
Pull out and remove the container and drip tray from the unit.
Rinse off the capsule, container and drip tray under warm running water. Set aside on a clean towel to dry.
Lift off the water tank and empty any leftover water.
Run warm water into the tank to rinse it. Empty it out and set it aside on the towel to dry.
Wipe the outside of the unit with a clean, lint-free cloth dampened with warm water. Use a drop of a gentle liquid soap, applied to the wet cloth, to remove tough residue.
Fill the water tank with the descaler provided by the manufacturer and the amount of water specified on the descaler packet.
Place a large ceramic cup or other appropriately-sized container securely on the drip tray underneath the coffee outlet.
Lift up the top lever and slide in the filter included with the descaler. Close the lever.
Press both coffee cup graphic buttons at the same time to start the descaling process. After the descaling solution runs through, empty it from the cup. Refill the water tank again with the solution and water and run a second cycle. Empty the solution from the cup again.
Lift up the lever and remove the filter from the machine. Close the lever. Rinse out the water tank with fresh water. Rinse the machine parts. Press the coffee cup buttons again at the same time and hold for three seconds to exit the descaling function.
