During the descaling program, the indicators on the control panel on the lid light up sequentially to indicate that the machine is descaling. The descaling program takes about 35 minutes. When the descaling program is finished, the Calc-Clean indicator flashes rapidly.

Warning: Never interrupt the descaling process!
