Component Maintenance - Filters and Tanks: Check and replace the filters according to the manufacturer's recommendations. Also, make sure the water and coffee tanks are cleaned regularly. - Milk System: If the machine uses milk, cleaning the frothing system is essential to prevent bacteria from forming. 3. Descaling - Regular descaling: Hard water can cause limescale deposits inside the machine. Use a descaling product according to the supplier's instructions to avoid operating problems. 4. Functionality Check - Constant Testing: Periodically check that the machine is working properly, including all coffee brewing functions, water temperature and pressure.
