How to Clean and Descale an Espresso Machine
It takes great beans and a great grind to make a desirable shot of espresso, but learning how to clean an espresso machine can help prevent minerals and oils from building up and altering the taste of your beverage. Regularly cleaning and understanding how to descale your espresso machine can make all the difference.
WAYS TO CLEAN AN ESPRESSO MACHINE
For the best-tasting espresso, an espresso machine that’s used often should be wiped down daily and the portafilter and basket should be rinsed out with every use. In addition, a deeper clean, which involves washing the individual parts, should take place weekly to help keep the machine and its parts free of residue and impurities.
Descaling your espresso machine with vinegar or a descaling solution at least once a year is also key to maintaining your appliance and ensuring delicious results.
The items you’ll need to keep your espresso maker clean are simple. In addition to the vinegar or specialized solution you’ll need for descaling, a daily or deep cleaning requires only a soft, clean towel and a little soap and water to get the job done.
TIP: START WITH GREAT WATER
Espresso only requires a few ingredients so everything you put in your espresso maker matters, including water. Starting with good filtered water can improve the taste and help minimize the concentration of dissolved minerals in your espresso machine. If you are using filtered water straight from the refrigerator, try KitchenAid® Refrigerator Water Filters.
HOW TO DESCALE AN ESPRESSO MACHINE
Descaling is removing mineral buildup from your espresso machine by flushing it with vinegar and water or a descaling solution. This should happen at least once a year, but if you’re not using filtered water, or your water is hard and has a higher mineral content, you might need to descale more often.
WHAT CAN YOU USE TO DESCALE AN ESPRESSO MACHINE?
A descaling solution is ideal, but if you don’t have any, and your owner’s manual indicates that vinegar won’t harm your machine, you can make a cleaning solution containing the ratio of vinegar and water recommended for your type of machine.
ESPRESSO MACHINE DESCALING INSTRUCTIONS
To descale your espresso machine, fill the water reservoir with a descaling solution, following the product’s instructions. Then run a brew cycle (without coffee grounds) to help clear mineral buildup. Rinse the reservoir and refill it with fresh water, then run another cycle to fully flush the system.
There are many different types of espresso machines, so before descaling, check your owner’s manual for the proper instructions on how to descale your make and model.
WHAT HAPPENS IF YOU DON’T DESCALE YOUR ESPRESSO MACHINE?
If you don’t descale your espresso machine it can cause mineral buildup that may affect the taste of your espresso and keep your machine from running optimally. Descaling your appliance at least once a year or more, if you’re not using filtered water, helps remove impurities while ensuring your espresso machine functions properly.
SEMI-AUTOMATIC ESPRESSO MACHINE DESCALING INSTRUCTIONS
Use the following steps to descale a semi-automatic espresso machine such as a KitchenAid® semi-automatic espresso machine with a descaling solution.
(Please note, the steps for descaling a coffee maker will be a bit different.)
STEP 1. FILL WATER TANK WITH DESCALING SOLUTION
Fill a clean water tank with the recommended volume of descaling solution and water.
STEP 2. START THE CLEAN CYCLE
Place a container below the group head and steam wand to catch the water and cleaning solution, then press the Clean cycle button.
STEP 3. REPEAT
Empty the container and repeat. How many times you need to repeat the descaling process depends on the soil level of your machine and the manufacturer’s instructions.
Some machines have an indicator light to let you know when it’s time to descale. If your machine is sputtering or the liquids aren’t flowing freely, this is another sign that your machine might need to be descaled.
If you’re going on vacation and you won’t use your machine for a while, you might want to descale your espresso machine when you return to flush out any deposits that might have accumulated while you were away

HOW TO CLEAN AN ESPRESSO MACHINE
Before you start cleaning your espresso machine, it’s important to understand what parts are included in it and whether or not they are dishwasher safe, or should be cleaned by hand.
Two of the most important parts of an espresso machine are “the group” or “group head” which is the heart of the machine and the “portafilter,” which holds the coffee grounds and is set inside a handle. These two parts connect the water and grinds to create the espresso. The portafilter should be tapped and rinsed to empty it of any residual grounds every time your machine is used.
The steam wand, used to heat and froth milk, should be purged and wiped down after every use and rinsed with water after you’re done brewing.
A KitchenAid® semi-automatic espresso machine includes the following parts:
Espresso machine
Portafilter
Coffee scoop
Tamper
Milk pitcher
Water tank
- 4 filter baskets
Steam wand
Drip tray
Cleaning brush
Milk tank
WHAT CAN YOU USE TO CLEAN YOUR ESPRESSO MACHINE?
Use a clean, soft, damp cloth to wipe the exterior of your espresso machine. Place the drip tray, portafilter, filter baskets, milk pitcher and drip tray plates in a sink of warm, soapy water to wash, then rinse clean. You can dry them with a cloth but avoid using abrasive cleansers or scouring pads.
HOW OFTEN SHOULD YOU CLEAN YOUR ESPRESSO MACHINE?
If you regularly use your espresso machine in your morning routine, it’s best to wipe it down daily. Clean the steam wand and rinse the portafilter and basket after each use. You can wash the other parts of your appliance in warm, soapy water weekly.
For a deeper clean, consider descaling your espresso machine once a year—or more often if you’re not using filtered water—to help prevent mineral buildup. You may have an indicator light that alerts you when to descale. If you notice your appliance isn’t running as smoothly as normal, descaling may help resolve that issue.
ESPRESSO MACHINE CLEANING INSTRUCTIONS
Before you begin deep cleaning your espresso machine, make sure the machine and its accessories have cooled and the machine is unplugged. Then follow these step-by-step instructions.
NOTE: Never use abrasive cleansers or scouring pads to clean your espresso machine.
STEP 1. EMPTY THE DRIP TRAY
When the drip tray indicator becomes visible, empty the drip tray.
STEP 2. WIPE DOWN THE ESPRESSO MACHINE
Wipe the espresso machine and the group head with a clean, soft, damp cloth.
STEP 3. WASH ESPRESSO MACHINE PARTS
Wash the drip tray, portafilter, filter baskets, milk pitcher and drip tray plates in warm, soapy water. Rinse with clean water. Dry with a soft cloth.
STEP 4. CLEAN THE STEAM WAND
Clean the steam wand after every use by selecting water. Position the wand over a cup or the drip tray and press the start/cancel button. Wait 3-5 seconds, then press the button again to stop. Wipe the wand with a soft, damp cloth.
