Daily Maintenance

Regular maintenance is crucial to ensure the optimal performance of your espresso machine. Daily cleaning helps to prevent the buildup of coffee oils and residues that can affect flavor and machine longevity.

  • Flush the Group Head: After each use, run water through the group head for about 10 seconds. This removes any leftover coffee grounds and oils.
  • Clean the Portafilter: Remove the portafilter and rinse it under hot water. Use a brush to scrub any coffee residue from the basket.
  • Empty the Drip Tray: Check and empty the drip tray to avoid overflow and maintain hygiene.

These simple steps should be part of your daily routine to keep your espresso machine in peak condition.

Weekly Cleaning

In addition to daily maintenance, a more thorough cleaning should be conducted on a weekly basis. This involves deeper cleaning tasks that help maintain the machine’s components.

  • Backflush the Machine: Using a blind filter, run a backflush cycle with a cleaning detergent specifically designed for espresso machines. This helps to remove oils and coffee particles from the group head.
  • Clean the Steam Wand: Purge the steam wand after each use, and once a week, soak it in a cleaning solution to remove any milk residue.
  • Descale the Machine: Depending on the hardness of your water, descale your machine weekly or monthly. Use a descaling solution and follow the manufacturer’s instructions.
