Troubleshooting
Most bad shots get blamed on the machine when the actual cause is grind size, dose, or an uneven tamp. This hub is built to help you diagnose the difference: what a sour, watery, fast shot is telling you versus a bitter, sluggish one, and what to actually change before you consider buying anything new.
Sour or Watery Shots
Usually a sign the grind is too coarse or the shot ran under 20 seconds. Here’s how to fix it.
Bitter or Sluggish Shots
Often caused by a grind that’s too fine, choking the puck and over-extracting past 35 seconds.
Channeling
What it looks like (thin, sour, squirting streams), why uneven distribution causes it, and how to prevent it.
Inconsistent Shots
When the same recipe pulls differently every time, the grinder is usually the culprit, not you.
Is It Technique or Equipment?
