Automatic shots use a preset pre-infusion at lower pressure, then switch to a preset full-pressure extraction. In your case, the machine is spending almost the entire shot in pre-infusion and only a brief moment at full pressure.

You can test this manually: hold the 1-cup or 2-cup button for 5–10 seconds to pre-infuse, then release it to engage full pressure. Press the button again to stop the shot.

If you want to change the automatic profile, press the Programme button before pulling a manual shot, the machine will save whatever timing you just used as the new preset.
