After an interrupted descaling cycle
Empty and thoroughly rinse the tank. Fill with fresh water to Calc / Clean and switch on; let the automatic rinse finish. Before making drinks, remove the milk accessory. Select hot water and press start/stop; repeat dispensing until half a tank has run through. Then brew 2 cups without adding coffee. For each cup, select a single coffee drink, hold aroma strength for 3 seconds to select pre-ground coffee, and press start/stop. Select pre-ground mode again for the next cup. The machine will need another complete descaling cycle as soon as possible.
When the alarm is on and start flashes
Fill the water tank, put a cup under the classic milk frother and press the flashing start/stop button. Keep clear: small jets of hot water come from the frother.
