Troubleshooting

Low pressure or no coffee is extracted

Start with the simple checks first:

• Grind finer if you want higher pressure, especially because pre-infusion changes the way pressure ramps up.
• Confirm that you picked the correct dose file for your basket.
• If your basket has more headspace than expected, review the headspace-dependent logic in How Automatic Pro v2 Works.
• In time mode, remember that the last phase may need to be shortened or extended to match your real flow.

The shot tastes sour or salty

Try:

• A higher ratio like 1:2.5+
• A slightly higher temperature
• The stable v2 branch if you are currently experimenting on vIT3

The shot tastes bitter or dry

Try:

• A lower ratio like 1:1.5-
• A slightly lower temperature
• A less aggressive grind if the flow is stalling late in the shot

Time mode feels inconsistent

Time mode is most useful as a practical approximation when no scale is available.

• Use the formula from Quick Start / Dialing In as the baseline.
• If the shot ends too early or too late, adjust the last phase duration to reflect your real observed flow.
• If you do use a scale, weight mode is usually the more reliable way to stop the shot.

Testing branch caveats

The vIT3 branch is intentionally marked as experimental.

• Expect edge cases and occasional errors.
• Use it for feedback and experimentation, not because you need the most conservative recommendation.
• Share your findings on GaggiMate Discord if you adapt the profile to new doses or basket styles.
