With normal use, your espresso machine will build up coffee residue that can cause your machine to not be as efficient. Leftover coffee also can make your coffee have an off taste. Mold can begin to grow and can eventually make you sick if left unattended. Cleaning your espresso maker can be a tedious task due to the small parts and hard to reach places. Daily cleaning will prevent the buildup of residue and can make cleaning it easier.

Daily Cleaning

Step 1

Unplug the espresso machine before you clean it.

Step 2

Place the filter basket and the carafe in a sink full of warm soapy water. Scrub gently to remove any coffee or water stains. You also can wash these items on the top shelf of your dishwasher, as they are dishwasher safe.

Step 3

Wipe off the exterior of the espresso machine with a clean, dry cloth. You may add cool water to remove any dirt or stains. Dry the machine with a clean, dry cloth.

Step 4

Rinse the interior of the water reservoir with cool water. Repeat this two to three times to remove any leftover coffee residue.

Decalcifing Your Machine

Step 1

Decalcify your machine once a month if you have hard water, and once a year if you have soft water. According to Krups, you should decalcify if it takes longer to prepare your espresso and if you begin to hear increased noise when the water begins to boil.

Step 2

Fill the water reservoir on the machine completely full of warm water. Turn the espresso machine on and allow the water to cycle through. The heat and the water will help move some of the loose particles inside the machine.

Step 3

Mix together a pack of Krups descaling powder and a half of a quart of water. You also may use 3 ounces of white wine vinegar and 20 ounces of water.

Step 4

Pour the solution into the water reservoir. Run the liquid through twice. Allow it to cool before you pour it back into the machine.

Step 5

Run two carafes of water through the machine to make sure all traces of the cleaning solution is gone.
