Maintaining and cleaning your 15-bar espresso machine is essential to ensure its longevity and performance. Here are some tips on how to properly care for your machine: 1. Regularly descale your espresso machine: Over time, mineral deposits can build up in your machine, affecting its performance. To prevent this, it is important to descale your machine regularly. Use a descaling solution recommended by the manufacturer and follow the instructions carefully. 2. Clean the portafilter and filter basket: After each use, remove the portafilter and rinse it with warm water to remove any coffee grounds. Also, clean the filter basket to prevent any clogs. You can use a brush to scrub away any residue. 3. Wipe down the steam wand: The steam wand can easily get clogged with milk residue if not cleaned properly. After each use, purge the steam wand by releasing steam for a few seconds. Then, wipe it down with a damp cloth to remove any milk residue. 4. Clean the group head: The group head is where the coffee is extracted, so it is important to keep it clean. Use a brush to remove any coffee grounds or residue from the group head. You can also run a cleaning cycle with a cleaning tablet to ensure it is thoroughly cleaned. 5. Check the gasket and seals: Inspect the gasket and seals on your espresso machine regularly for any signs of wear and tear. If you notice any damage, replace them to prevent any leaks or issues with the machine. 6. Empty and clean the drip tray: The drip tray collects any excess water or coffee that drips from the machine. Empty the drip tray regularly and clean it with warm, soapy water to prevent any mold or bacteria buildup. 7. Use filtered water: To prevent mineral buildup in your machine, use filtered water instead of tap water. This will help prolong the life of your espresso machine and maintain its performance. 8. Store your machine properly: When not in use, make sure to store your espresso machine in a cool, dry place. Avoid storing it near heat sources or in direct sunlight, as this can damage the machine. By following these tips on maintaining and cleaning your 15-bar espresso machine, you can ensure that it performs at its best for years to come. Proper care and maintenance will not only extend the life of your machine but also improve the quality of your espresso.
