How to Clean and Maintain Your Espresso Machine (Daily, Weekly, Monthly)

An espresso machine is a small piece of industrial equipment. Treated well, it runs for 10–15 years. Neglected, it dies in two or three. The difference is a maintenance routine that takes about 5 minutes a day.

Daily (every brewing session)

1. Purge the group head before locking in the portafilter — flushes old water sitting in the group.
2. Wipe the steam wand immediately after each use with a damp cloth, then purge it for one second.
3. Knock out the puck as soon as the shot finishes.
4. Rinse the portafilter and basket under hot water — never let coffee oils dry on metal.
5. Wipe the drip tray.

These five steps prevent 80% of long-term problems.

Weekly

1. Backflush with water (machines with 3-way solenoid valves only — most prosumer machines). Insert the blind basket, lock in the portafilter, run the pump for 10 seconds, release for 10 seconds, repeat 5 times.
2. Backflush with espresso machine cleaner (Cafiza is the standard). Same procedure as above with a 1/2 teaspoon of cleaner in the blind basket. Then backflush with water 5–10 times to rinse.
3. Soak the portafilter, basket, and shower screen in warm Cafiza solution for 20 minutes. Rinse thoroughly.
4. Clean the steam wand internals by submerging the tip in a cup of water with a pinch of Cafiza, then steaming. Purge thoroughly afterward.
5. Clean the drip tray and water reservoir.

Monthly

1. Remove and clean the shower screen completely. Unscrew it, soak in Cafiza, scrub the bolt with a brush.
2. Inspect the group gasket. If it's hard, cracked, or shots are spraying past the portafilter, replace it. Gaskets are cheap and a 5-minute job.
3. Run a complete reservoir flush to clear any sediment.

Descaling (every 1–3 months depending on water)

Limescale is the slow killer of espresso machines. Use bottled descaling solution (like Urnex Dezcal) per your machine's instructions. Never use vinegar — it leaves residues that affect taste and damages some seals.

The frequency depends on water hardness:

• Soft water (under 50 ppm): every 3–6 months.
• Medium water (50–150 ppm): every 1–3 months.
• Hard water (150+ ppm): every month, or switch to bottled/filtered water.

Many enthusiasts use TWW (Third Wave Water) or empty-and-remineralize systems to eliminate scaling entirely.

Signs your machine needs attention

• Shots taste increasingly bitter or muddy despite good beans.
• Pressure gauge reads lower than usual.
• Water flow is reduced or uneven.
• Steam wand produces wet, weak steam.
• Machine takes longer to heat up.

Any of these means it's time to clean and descale, in that order.

The mindset

Treat the machine like a chef's knife: clean it the moment you finish using it, not later. Five minutes a day saves you a $300 service call every other year — and your shots taste noticeably fresher every morning.
