Machine Cleaning

  •  Do not use water sprays, metal or abrasive tools (such as steel wool, metal brushes, needles, etc.), or any abrasive detergents.
  •  We recommend a clean, damp microfiber cloth or sponge for most case and frame cleaning.
  •  For cleaning the group and portafilter, only use coffee and espresso machines are detergents
  • Make sure to purge and wipe down the steam wand of any residual milk after every use.

Daily Maintenance

  • Clean the case panels, frame and drip tray with a clean microfiber cloth or sponge as needed.
  • Empty drip tray and clean out any residual coffee solids
  • Empty portafilter after use and rinse with hot water before reinserting into group.

Weekly Maintenance

  • While hot, scrub group gasket of any residual coffee oil with the included brush.
  •  Insert the blind basket into the portafilter, place in group, and backflush.
  •  To backflush, lift the group lever and run the pump for 15 seconds. Lower the group lever to relieve pressure. Repeat 10-15 times.
  •  Soak your portafilter and baskets in hot water and/or a cleaning detergent like Cafiza to loosen coffee oils. Wipe clean.

Periodic Maintenance

  •  Inspect group gasket and diffuser screen for excess coffee buildup or wear. If needed, replace with authorized components
  •  To clear excess coffee oil from gasket and screen, repeat weekly backflush routine using a dedicated cleaner like Cafiza

With the use of filtered or bottled water, regular descaling is not required. Damage to your machine can result from improper descaling. Descaling at home is not recommended. Damage to components or clogged lines from descaling are not covered under warranty.

Tips And Tricks

  • Be Clean
    Always start with a blank slate for your espresso. Both your portafilter and group should be clean and clear of any old grinds or residual coffee oils that may impart off-flavors or slow the flow into your cup.
  • Coffee Quality
    Make sure the coffee you are using is ideal for espresso. While pre-ground coffee may work in an emergency, you’ll find much better results if you use fresh-roasted coffee ground in your own home.
  • Grind Matters
    Good brew pressure is difficult to achieve without a good grinder. Espresso-ground coffee should resemble the consistency of powdered sugar, and should be of uniform and consistent particle size. If your grind is too coarse, shots will flow fast and feel watery. Too fine, and shots will flow too slow or not at all.
  • Consistent Dosing
    Make sure to dose the right amount of coffee into your basket every time. Your Bello comes with standard Italian single and double baskets, made for roughly 7-gram and 14-gram doses of coffee. An espresso scale and high-quality grinder is highly recommended.
  • Shot Flavor
    Focus on dialing in your grind for flavor first. Don’t worry if your shot time or dose differs slightly from the recommended parameters on the bag.
  • Milk Steaming
    There are two main stages to milk steaming. The first is texturing: bring your steam wand tip near the surface of your milk to incorporate air. Fine foam drinks like lattes require lessair, while drinks like cappuccinos require more texturing. The second is incorporating: sink your steam wand down into the milk. This heats the milk and swirls in your layer of milk foam simultaneously.
