5.2 Descaling (Easy Cleaning Mode)

Mineral deposits from water can affect coffee maker performance. The machine will automatically remind you to clean after approximately 90 uses.

Note: After using the coffee machine for more than 3 months, use a specially formulated descaler or citric acid for effective cleaning to prevent a decrease in heating performance.
