Figure out what your espresso machine is trying to tell you
Pick the symptom that matches what you see at the machine. The tool narrows down the most likely causes, gives you fast checks in the right order, and points you to deeper guides when you need them.
Best for quick answers
- No power or random shutoffs
- Weak flow, choking, or no espresso
- Sour, bitter, or watery shots
- Steam wand sputtering or no microfoam
- Water leaks and messy puck issues
Step 1
Choose the symptom you want to fix first
Most home baristas chase three problems at once. Start with the one that blocks a drink entirely, then work down the list.
Select a symptom to get a tailored checklist
You’ll see likely causes, quick tests, and the next best guide or gear recommendation without digging through five tabs.
Step 2
Prevent the repeat offenders
Most espresso headaches are maintenance or workflow drift, not catastrophic machine failure.
Weekly reset
Backflush if your machine supports it, purge the steam wand, and brush out old grounds before they turn into rancid sludge.
Water + grinder sanity check
If shots suddenly run wild, confirm the grinder setting didn’t move and your water tank, filter, or bean freshness didn’t quietly change.
Keep a tiny log
Shot time, dose, and taste notes beat guessing. Two or three lines in your notes app is usually enough to spot the pattern.
