LUCCA A53 / A53 Mini: Programming Volumetric Settings

Below are step-by-step instructions as well as a video to show you how to program your LUCCA A53 espresso machine for volumetric dosing. (Difficulty ☕)

Important Note: Your grind must be dialed-in to consistently pull shots at your preferred recipe in order for the machine's volumetric dosing to be accurate. The machine's volumetric dosing is only able to be set accurately if the grind and recipe is consistent.

Understanding Your Brew Pressure Gauge

First, power the machine on by pressing and holding the power button for 5 seconds. You will know the machine is on when the power button stays solid and the brew boiler set temperature light starts blinking.

Allow the machine to fully heat, then press and hold the power button again for 5 seconds. This will put the machine into its volumetric settings mode. You will know that the machine is in the volumetric settings mode when both the power light and the set temperature light blink.

Next, pull a shot using either the single shot or double shot button, and press the same button once you've reached your desired volume. 

Finally, press the power button one more time, and voila, your shot is timed for future use.

For new machines or when dialing in, we recommend setting both buttons to dispense ~4 fluid ounces of water from the bare group head. This will cause the shot buttons to act as manual shot buttons when pulling a shot. Pressing either button will start the shot, pressing the same button again will stop it. Once you've perfected your recipe, you can go back and program the shot buttons volumetrically.
