Frequently Asked Questions
Is it worth upgrading from an all-in-one style machine to a Diletta Alto?
Yes, Diletta Alto is a worthy upgrade into the “prosumer” grade of at-home espresso machines. It features a superior build quality, a timeless stainless steel body, and commercial-grade components.
The Diletta Alto Espresso Machine offers precise pressure control, ensuring consistent espresso extraction, and the dual boiler allows powerful simultaneous brewing and steaming.
The machine is designed for long-term use with customization options, making it ideal for serious coffee enthusiasts seeking a commercial-grade experience at home.
During normal usage, how often should I conduct service/maintenance on my Alto?
Maintaining your espresso machine will vary by frequency of use, but by following these general guidelines below, you can prolong the health of your machine.
Daily Maintenance:
After each use, flush the group head by running water through it to remove coffee grounds.
Rinse the portafilter and filter basket to prevent coffee residue buildup.
Steam Wand Cleaning: Purge the steam wand after each use and wipe it down to prevent milk residue buildup.
Weekly Maintenance:
Backflushing: Backflush the machine with clean water to clean the group head. Use a backflush detergent once a week to deep clean the internals.
Cleaning the Drip Tray: Empty and clean the drip tray to avoid mold and bacteria growth.
Monthly Maintenance:
Inspect Seals and Gaskets: Check seals and gaskets for wear and tear, replacing them as needed.
Change your water filter!
Annual Maintenance:
Once yearly, have the machine professionally serviced for a thorough inspection, cleaning, and any necessary repairs.
Descaling: Descaling should usually be performed once per year or as directed by your manual, and could be considered a deep clean, but it’s very important to follow your machine’s guidance for descaling. Many home machines should be taken to professional repair shops for descaling to avoid damaging the machine. If you use the correct water with the right mineral content, you likely won’t ever need to descale.
What is the warm up time for Diletta Alto?
The Diletta Alto typically requires around 25-30 minutes to fully warm up. This time allows the machine to reach a stable operating temperature, ensuring optimal brewing conditions for espresso extraction and steaming.
