Proper maintenance of an espresso machine

Maintaining an espresso machine is crucial for superior coffee taste and a long machine lifespan. Coffee contains natural oils that adhere to machine parts during extraction, and water, especially hard water, leaves limescale. Neglecting cleaning leads to the accumulation of deposits that spoil the taste of fresh espresso. A clean and properly functioning machine means consistently high coffee quality and machine longevity. That's why we're providing practical home barista tips on daily, weekly, and semi-annual maintenance of Brewsociety machines (Rocket, ECM, Profitec, Torre) – along with recommended products from our range.

Why regular espresso machine service is important

Espresso machine maintenance ensures temperature and pressure stability, and thus better extraction quality. Without regular care, oils coagulate within the group head and portafilter, and limescale in the heater and pipes can disrupt water flow and temperature. The result is milder or even stale aromatic notes in the cup. On the other hand, regular servicing extends the lifespan of the machine – instead of frequent breakdowns and expensive repairs, you invest only a few minutes a day in cleaning, with guaranteed better espresso results. In short, a clean machine = delicious coffee and fewer problems in the long run.

Daily espresso machine cleaning

• After each use: Immediately remove the used coffee "puck" from the portafilter and either knock it out into a knockbox. Briefly flush water through the group head (without the portafilter) to remove any remaining particles. Wipe the gasket (rubber seal) around the group head with a damp cloth and clean the steam wand of milk residue – release steam for a moment, then wipe the wand with a cloth . This prevents the accumulation of moisture and milk residue, which quickly become a bacterial risk.

• Before the first morning espresso: Once the machine is heated, run a little hot water through the group head to warm up the system and remove any "night dust." This morning rinse prepares the machine for more even extraction of freshly roasted beans.

• At the end of the day: Perform a backflush with clean water only (no detergent). Place a blind filter in the portafilter and activate the pump for 5–10 seconds, several times. You will see dirty water coming out: this process rinses fine coffee residue from the valve and group head . This will prevent residue buildup inside the valve even if your machine has a three-way valve designed for backflushing (like Rocket, Profitec, Torre, etc.).

Tips: To facilitate daily maintenance, invest in a good espresso cleaning kit. It usually contains blind filter baskets, special brushes for group head cleaning, and detergent in tablets or powder. Use soft cloths and a brush to avoid damaging the rubber or metal parts of the machine.

Weekly maintenance and cleaning

• Backflush with cleaning agent: Once a week (or more often if you use the machine intensively), perform a thorough backflush using a special espresso machine detergent. Fill the blind filter with appropriate powder or tablet (e.g., Urnex Cafiza, Puly Caff, Cafetto – products from the Espresso Coffee Shop range) and perform a procedure similar to flushing with water brewsociety.store. Detergents dissolve and remove stubborn oils and greasy deposits that plain water cannot. After cleaning, thoroughly rinse the system with clean water (perform several backflush cycles without powder) to prevent any chemical taste in the machine.

• Cleaning the shower screen and filter: Remove and thoroughly wash the group head shower screen and the mesh underneath it – this is where most residue accumulates. You can leave them in warm water to soak or clean them with a special deep-cleaning brush (often part of an espresso cleaning kit). Also, soak the portafilters and filter baskets in warm water with a little mild dish detergent – greasy coffee stains will come off easily, and the metal parts will shine.

• Cleaning the steam wand: Carefully unscrew and wash the steam wand (if possible), or use a thin needle/brush to clean the openings, as milk residue can also remain in them. Check and restore the blind-steam function (if your machine has this option) by releasing steam for a few seconds when empty.

• Exterior maintenance: Wipe the exterior parts of the machine with a soft (non-abrasive) cloth to remove milk residue and water droplets. A clean exterior will not directly affect extraction, but it maintains the professional appearance of your kitchen and prevents dust and dirt from entering the open parts of the machine.

Six-month maintenance: descaling and service

• Descaling: Every 3–6 months, it is essential to descale the system, especially if you do not use filtered water. Limescale accumulates in the boiler and pipes, reducing water flow and temperature stability. Follow the machine manufacturer's instructions – this usually involves running a solution of vinegar in water or a commercial descaling agent. Make sure all solution residue is completely rinsed, otherwise it can damage the machine or give an unpleasant taste to the espresso.

• Gasket replacement and lubrication: After 12–24 months of use (or sooner, if you notice water leaking at the edges of the portafilter), it is recommended to replace the gaskets on the group head. Old gaskets harden over time and lose elasticity, leading to poor sealing. When replacing them, wipe and lubricate the moving parts of the group head – for example, with E61 group heads, apply a small amount of food-grade silicone grease (silicone lubricant) to the top of the piston and the group-lever rings. This allows the lever and group head to operate smoothly without sticking. This procedure, although technical, can be done yourself with a little skill, or entrusted to a professional technician.

• Complete semi-annual service: Every 6-12 months (depending on intensity of use), it is advisable to perform a professional espresso machine service. This includes more detailed boiler cleaning, pump, valve, and thermostat checks, as well as machine calibration. Brew Society offers a 6-month service package, which covers all the aforementioned work – from descaling and gasket replacement to technical inspections. This way, you get complete care for your machine without your own involvement, and regular coffee machine service ensures your espresso machine operates reliably as new. As research shows, regular maintenance can significantly extend the machine's lifespan with minimal costs compared to potential repairs.

Recommended products and tools

For optimal maintenance, use special products: backflush tablets or powder (e.g., Urnex Cafiza, Cafetto Espresso Clean, Puly Caff) for weekly cleaning, descaling solution (e.g., detartrant), group head and steam wand brushes (metal or plastic), blind filter (blind filter basket), and food-grade silicone lubricant for gaskets. One useful addition is an espresso cleaning kit – a set with all these tools and products – which facilitates organized maintenance. Always choose products from verified sources to avoid damaging machine parts.

Conclusion

Proper maintenance of your espresso machine ensures that you will enjoy every cup as much as the first sip of your favorite espresso. Proper care not only improves the taste but also reduces the chances of malfunction and preserves your investment longer, with maximum machine performance.
