Why It’s Important To Clean An Espresso Machine
Keeping your espresso machine clean is crucial for several reasons.
First and foremost, regular maintenance ensures that your coffee maker continues to produce great-tasting espresso consistently.
Over time, oils and residue from coffee beans build up inside the machine, which can affect the flavor of your beverages. Cleaning your espresso machine helps prevent the formation of these residues, creating a better experience for both you and your customers.
If you are a barista or a café owner, you also need to maintain a hygienic environment for your clients. A clean espresso machine prevents the growth of bacteria and mold, which can lead to health issues for your customers. Your reputation as a professional and high-quality café relies on the cleanliness of your equipment.
Furthermore, proper maintenance extends the lifespan of your espresso machine. By regularly cleaning its various components, you can prevent clogs, blockages, and other issues that may cause damage to your machine.
This ultimately saves you money in terms of repair costs and the possibility of having to purchase a new coffee maker.
Lastly, a well-maintained espresso machine is more efficient, using energy and resources more effectively. This not only saves you on utility bills but also contributes to a more sustainable business model.
Daily Cleaning Process
Cleaning The Portafilter And Basket

Cleaning The Steam Wand
Steam wands must be cleaned regularly to prevent the buildup of milk leftovers+. After each use, wipe the exterior of the steam wand with a damp cloth to remove residue.
Next, purge the steam wand with hot water, to clear any remaining milk inside. For a deeper clean, use a steam wand brush to scrub the inside and remove any stubborn residue.
Cleaning The Drip Tray And Reservoir
It’s important to keep the drip tray and water reservoir clean to maintain the quality of your espresso. Empty the drip tray daily, rinse it with hot water, and scrub away any residue before returning it to the machine.
To clean the water reservoir, empty the tank and rinse it with hot water. Replace the water with fresh, filtered water to ensure the best-tasting espresso.

Backflushing And Descaling
Backflushing Process
Backflushing is essential for keeping your espresso machine’s components clean and free of coffee oils and debris. To begin the backflushing process, follow these steps:
- Remove the portafilter and empty it. Replace the filter basket with a blind basket or a cleaning disc to block water flow.
- Insert the portafilter back into the group head and lock it in place.
- Add a small amount of espresso machine cleaning powder to the blind basket.
- Turn on the pump for approximately 20 seconds or until the pump gets quiet, indicating the buildup of pressure. Switch off the pump to release the pressure.
- Repeat the process of turning the on and off the pump several times to ensure effective cleaning of the group gasket, dispersion plate, and shower screens.
- Remove the portafilter and rinse it thoroughly with plain water. Replace the blind basket with the regular filter basket and run a few plain water brew cycles to clear any remaining cleaning solution from the group head.
Descaling Process
Descaling your espresso machine is crucial to remove mineral deposits and prevent limescale buildup, which may affect the machine’s performance and taste of your espresso.
Here is a step-by-step guide to descaling your espresso machine:
- Prepare a descaling solution using a commercial descaling solution, white vinegar, or a mixture of citric acid with water. If using vinegar or citric acid, ensure a 1:1 ratio with water (e.g., 1 cup water with 1 cup vinegar).
- Turn your machine off and empty the water reservoir. Fill it with the descaling solution you prepared.
- Place a container to catch the solution under the steam arm or nozzle, then turn on the machine, allowing the solution to run through the steam arm and boiler for approximately 5 minutes.
- Pause for 15-20 minutes, allowing the descaling solution to take effect.
- Repeat steps 3 and 4 until the reservoir empties.
- Fill the reservoir with clean water and run the entire contents through the machine to rinse out any remaining descaling solution. You may need to do this twice to ensure there are no traces of the descaling solution left.
Removing And Cleaning Components
In this section, we will focus on removing and cleaning essential components of your espresso machine to ensure its longevity and optimal performance. Following these steps will help you maintain your machine in top condition.
Removing And Cleaning The Group Screen
First, turn off and unplug your espresso machine to ensure safety. The group screen is an essential part of the brewing process, as it’s responsible for distributing water evenly over the coffee grounds.
Over time, the group screen can become clogged with coffee particles, which may negatively impact the taste of your espresso.
Start by removing the portafilter and filter basket. Locate the group screen, which is usually held by a screw or just pressure. If necessary, consult your manufacturer’s instructions.
Once the group screen is removed, soak it in a cleaning solution, like a mixture of warm water and baking soda. Use a nylon brush to gently scrub away any debris. Rinse thoroughly with warm water and set aside to dry.
Removing And Cleaning The Steam Wand Nozzle
The steam wand nozzle is an essential component for producing well-textured milk for beverages like cappuccinos and lattes. Over time, milk residue can accumulate on the nozzle, affecting its functionality.
To clean the steam wand nozzle, first, remove it from the steam wand arm according to your machine’s specific instructions.
Soak the nozzle in a cleaning solution, and again use a small brush, to scrub away any milk residue inside and outside the nozzle.
Rinse thoroughly with warm water and allow it to dry before reassembling.
Removing And Cleaning The Reservoir And Tank
Begin by removing the water reservoir and tank according to the manufacturer’s instructions. Empty any remaining water and inspect for visible mineral deposits or scale.
To remove these deposits, fill the reservoir with a mixture of equal parts water and white vinegar or a descaling solution. Let it soak for at least 30 minutes, or as recommended by the manufacturer.
After soaking, scrub the tank and reservoir with a soft, non-abrasive cloth or a nylon brush to remove any stubborn deposits. Rinse the components with clean water multiple times to remove any residue before refilling with fresh water.
Reassemble the machine and run a few water-only cycles (around 10 seconds each cycle) to ensure everything is properly rinsed before using your espresso machine again.
Weekly and Monthly Cleaning Tasks
In addition to daily cleaning rituals, it’s important to pay attention to weekly and monthly cleaning tasks. This ensures that your machine stays in top-notch condition and consistently delivers great-tasting espresso.
For weekly cleaning, follow these steps:
- Remove and rinse the brew group with lukewarm water to clear away coffee grounds and oil residues. Make sure the unit is thoroughly dried before reassembling it back into the machine.
- Clean the group head by scrubbing it with a machine brush to loosen and remove any remaining coffee grounds. This will help prevent build-up and maintain optimal brewing conditions.
For monthly cleaning, it’s necessary to perform a more in-depth process:
- Chemically clean the espresso machine with a specially formulated cleaner. Dissolve the cleaner in fresh water, following the instructions listed on the cleaning product to prepare the solution.
- Perform a detergent backflush by following these steps:
- Remove the regular coffee basket from the portafilter and replace it with the blind basket.
- Add ½ teaspoon of espresso machine cleaning detergent into the blind basket and insert the portafilter into the group head.
- Use the espresso machine’s manual button or lever to activate the pump and allow it to run for ten seconds. Repeat this process until the water coming out is clear.
- Use coffee oil remover tablets to remove oil from the filter on the brew group. This step may vary depending on your machine’s manufacturer, so consult your espresso machine’s manual for specific instructions.
