Common Espresso Issues & Troubleshooting
Espresso Shots Running Too Fast
Usually the grind is too coarse — we'll help you find the sweet spot for your beans and machine.
Shots Too Slow or Choking the Machine
Grind too fine, too much dose, or over-tamping. Common on Breville Barista Express — we'll walk you through adjustments.
Sour or Bitter Espresso
Sour = under-extracted, bitter = over-extracted. We'll help you adjust grind, dose, and yield for balanced espresso.
Inconsistent Shots Day to Day
Could be distribution, stale beans, grinder retention, or temperature. Small changes make a big difference.
Milk Not Texturing / No Microfoam
Steam wand technique, milk temperature, and jug position all matter — we'll help you get smooth microfoam.
Machine Not Working / Error Lights
No power, leaking, poor pressure, or error lights on your Breville or DeLonghi? We'll help troubleshoot.
Espresso Machine Care Tips
- Always let your machine warm up fully before pulling shots — at least 15-20 minutes
- Never run the steam wand dry — always purge before and after steaming milk
- Use filtered water to extend machine life and improve espresso taste
- Backflush your Breville regularly with cleaning tablets as per the manual
- Descale your espresso machine every 2-3 months depending on water hardness
Frequently Asked Questions
What grind size should I use on my Breville Barista Express?▾
Start around grind size 5 on the internal Breville grinder with the default 'razor' dose. Aim for 30ml of espresso in about 25-30 seconds. Adjust finer if shots run fast, coarser if they choke. Every bean is different so you'll need to re-dial when you change beans.
Why are my espresso shots sour on my DeLonghi?▾
Sour shots on a DeLonghi Dedica or La Specialista mean under-extraction — the water passed through the coffee too quickly. Try grinding finer, increasing your dose slightly, or tamping more evenly. Also check your beans aren't too fresh (2-7 days off roast is the sweet spot).
How do I know when my espresso is dialled in properly?▾
A well-dialled shot should pour like warm honey, starting with a few drips then a steady stream. Aim for a 1:2 ratio (e.g. 18g in, 36g out) in 25-30 seconds. It should taste balanced — not sour, not bitter, with some sweetness.
Why do I need to change grind size when I change coffee beans?▾
Different beans have different densities, roast levels, and ages, which all affect how water flows through them. A grind setting that works for one bean will likely be wrong for another. Always re-dial when switching beans.
How do I texture milk properly on my Breville or DeLonghi?▾
Purge the steam wand first, position the tip just below the milk surface at a slight angle, and introduce air for 2-3 seconds. Then submerge the tip to create a whirlpool. Stop when the jug is too hot to hold (~65°C). Tap and swirl to remove bubbles.
What's the best coffee-to-water ratio for espresso?▾
The standard starting point is a 1:2 ratio — for example, 18g of ground coffee yielding 36g of liquid espresso. Ristretto is around 1:1.5, lungo around 1:3. Adjust to taste, but 1:2 in 25-30 seconds is the universal starting point.
