The Auto Calc Clean process is in progress. After you have used the appliance for some time, it will automatically perform a Calc Clean process to remove scale from the steam generator.
When the Auto Calc Clean process takes place, the blue Auto Calc Clean light flashes and you will hear short beeps and occasional pumping and clicking sounds. Make sure there is enough water in the water tank. If the water tank is empty, the red 'water tank empty' light flashes. Detach the water tank and refill it with tap water.
When the Auto Calc Clean process is completed after approx. 2 min., the beeping stops and the Auto Calc Clean light goes off. The red Calc Clean tank light flashes. Detach the water tank and hold it over a sink. Press the Calc Clean tank emptying button on top to empty the Calc Clean tank into the sink. Refill the water tank and reattach it to the steam generator. The red Calc Clean tank light goed off and the appliance starts heating up. After approx. 2 min. the appliance is ready for steam ironing. When you hear 2 beeps and the light in the active steam selection button stops flashing and stays on, you can start steam ironing by pressing the steam trigger.
