How do I replace the anti-scale filter?

Switch off the product, let it cool completely, and disconnect the mains plug. Pull the water tank out of the base station, empty it, then pull the used anti-scale filter upwards out of its slot and insert the new one, pressing it down firmly. Reinsert the water tank, reconnect the power, switch the product on, and press and hold the steam mode button [3] for approximately 5 seconds until the indicator [9] goes off. (Page 16)
