To ensure the longevity of your espresso machine and maintain the quality of your coffee, regular cleaning and descaling are essential.
In this Coffee Expert guide, we’ll walk you through the process of cleaning and descaling your espresso machine to keep it in tip-top condition and make sure you’re always serving up the perfect cup of coffee!
Understand Your Espresso Machine
Before diving into the cleaning process, it’s important to familiarise yourself with your espresso machine. Different machines may have specific cleaning requirements or disassembly processes, so consult your machine’s user manual for any specific instructions.
The Daily Cleaning Routine
To keep your espresso machine in optimal condition, it’s essential to perform daily cleaning tasks. These tasks help prevent the build-up of coffee residue, oils, and mineral deposits.
Clean the Group Head and Portafilter
- Remove the portafilter from the group head.
- Use a group head brush to scrub away any coffee residue from the group head and portafilter.
- Rinse the portafilter and basket under warm water to remove any remaining residue.
- Reattach the portafilter to the group head and run water through it for a few seconds to flush out any remaining debris.
Backflush the Group Head
- Insert a blind basket (a basket without holes) into the portafilter.
- Add a small amount of espresso machine cleaner, following the manufacturer’s instructions.
- Lock the portafilter into the group head and run the espresso machine for 10 seconds.
- Release the pressure and allow the water to flow out through the pressure relief valve.
- Repeat this process several times until the water runs clear.
Clean the Steam Wand
- Wipe the steam wand with a damp cloth immediately after each use to prevent milk residue from building up.
- Purge the steam wand by releasing steam for a few seconds to clear any milk residue from the inside.
- At the end of the day, remove the steam wand tip and soak it in warm, soapy water for a few minutes. Scrub with a small brush, rinse, and reattach.
The Weekly Cleaning Routine
Performing these tasks on a weekly basis will help maintain the overall cleanliness and performance of your espresso machine.
Clean the Group Head Screen
- Turn off the espresso machine and allow it to cool down.
- Remove the group head screen by unscrewing it with a suitable tool (e.g., a flathead screwdriver).
- Soak the screen in a solution of warm water and espresso machine cleaner for approximately 30 minutes.
- Use a brush to remove any remaining residue, rinse thoroughly, and reinstall.
Clean the Drip Tray and Drain
- Remove the drip tray and drain grate.
- Empty any liquid and dispose of coffee grounds.
- Scrub the tray, grate, and drain hole with a brush and soapy water.
- Rinse thoroughly and reinstall.
Descaling Your Espresso Machine
Descaling is the process of removing mineral deposits (scale) that form inside the espresso machine due to the use of hard water.
It’s essential to descale your machine regularly, as scale build-up can affect the taste of your coffee and cause damage to the machine.
Prepare the Descaling Solution
Purchase a descaling solution specifically designed for espresso machines, or make your own solution using a 50/50 mix of white vinegar and water.
Run the Descaling Solution Through the Machine
- Empty the water reservoir and refill it with the descaling solution.
- Turn on the espresso machine and run water through the group head and steam wand until the reservoir is empty. This will help to dissolve and remove mineral deposits from the internal components of the machine.
Flush the System
- Refill the water reservoir with fresh water.
- Run water through the group head and steam wand until the reservoir is empty to flush out any remaining descaling solution.
Repeat if Necessary
If your espresso machine has not been descaled for a long time or if you notice that the water flow is still slow, you may need to repeat the descaling process.
Reassemble and Test Your Espresso Machine
After cleaning and descaling your espresso machine, it’s time to reassemble any removed components and test the machine to ensure everything is functioning properly.
Reattach the Group Head Screen
- Ensure the group head screen is clean and free of any residue.
- Reinstall the screen by screwing it back into place.
Reattach the Steam Wand Tip
- Make sure the steam wand tip is clean and free of any milk residue.
- Reattach the tip to the steam wand.
Test the Espresso Machine
- Refill the water reservoir and turn on the espresso machine.
- Run water through the group head and steam wand to ensure there are no leaks and that the water flow is consistent.
- Brew a shot of espresso to confirm that the taste and quality of the coffee have improved.
