The brew group is the most important part of the espresso machine, as this is where the coffee is actually brewed. This component can be easily removed and cleaned. After prolonged use, however, it is worth replacing to fully refurbish your appliance. The brew group should be cleaned and lubricated monthly, or at least every two months. The materials required for lubrication are available in our webshop. Our colleagues are happy to help and explain how to maintain the brew group.
