a) Preparing for decalcification
For safety reasons, once the decalcification process has started it must not be stopped until the system
has been rinsed (see process f). All operating modes of the appliance are blocked until decalcification
has been completed.
Set the control panel to “Off”.
• Turn OFF the water supply or switch OFF the water pump.
• Open a hot water faucet to relieve pressure in the system.
• On all water faucets attach the warning sign “Caution decalcification in progress” in a clearly
visible position. Warning signs are enclosed with the decalcification tablets.
