Portafilter machines are true precision devices. To ensure they work reliably for many years, it's worth keeping an eye on wear parts and using high-quality accessories. Even though spare parts often have to be ordered directly from the manufacturer or specialist dealer, it's good to know which parts regularly need attention.

Typical spare parts for portafilter machines

Seals and O-rings
Over time, seals harden. Replacing them every 6–12 months ensures that the brew group and portafilter seal tightly.

Filters and shower screens
Worn filters lead to uneven extraction. Even a new precision filter can noticeably improve the espresso.

Valves and pumps
If no pressure builds up or water drips, solenoid valves or pumps are often affected. Replacement is usually easily available.

Heating elements and thermostats
Temperature problems are often caused by defective thermostats or heating elements. These are classics in older machines.

Useful accessories for better espresso

Tamper and Leveler
A perfectly fitting tamper ensures even pressing of the coffee grounds. A leveler perfectly complements the setup.

Scales and timers
For consistent results, scales with integrated stopwatch or brew-by-weight function are helpful.

Milk jugs and latte art tools
Anyone who loves cappuccino or flat white can't do without the right jug. Different sizes and spouts make the difference.

Conclusion

Even if you can't always buy spare parts in your favorite shop, it's worth keeping an eye on the typical wear parts. Combined with high-quality accessories, the portafilter machine remains reliable – and every espresso tastes just as it should.
