Ascaso Steel DUO: User Manual

In this manual, you should find everything you need to operate and maintain your Ascaso Steel DUO Programable espresso machine.

Please read carefully before operating your thermoblock, vibratory pump espresso machine. Check out our website for specifications of the Ascaso Steel DUO programmable espresso machine, including accessories and other details. For setup information, please take a look at the setup guide.

Getting Started:

After reading through the Ascaso Steel DUO setup guide, test your water. Espresso machines have specific water requirements. There are two primary considerations: filtration and hardness. Please carefully read about the importance of water in espresso to understand how water affects your espresso machine. For further learning, check out Coffee School's Water 101

Note: It's essential to test your water, filter, and soften to obtain 35-85 ppm to avoid scale and damage to your machine. RO (reverse osmosis) or distilled water does not contain enough mineral content and could cause issues with your machine. The SCA Water for Brewing Standards explains what's needed to obtain water suitable for your machine and coffee.
