Symptom-first fixes for espresso problems — sour shots, channeling, weak steam, and machine faults — diagnosed by cause, not guesswork. Each guide walks the likely causes in order of probability, with the bench test that isolates the one you actually have.

Start from the symptom that matches your shot and work down the checklist; most fixes take less than ten minutes. Still stuck after the basics? The machine and grinder guides carry the bench data behind each symptom, so you can compare your readings against ours.
