Avanza: How often does the machine need to be descaled?

Avanza: This depends on the water hardness setting and ranges from 30 to 150 litres of water usage. If you insert a water filter via the menu, the water hardness will be set to soft water. The manual explains how to adjust the water hardness setting. The descaling symbol will disappear from the display after completing the programme. If the programme has been interrupted, it must be run again.
