The water softener filter is exhausted.
Follow the step-by-step guide:
Press "Next" to continue.
The filter last about two months if the coffee machine is used normally. If the coffee maker is left unused with the filter installed, it will last a maximum of three weeks.
To activate the filter, run tap water through the hole in the centre of the filter until it comes out of the openings at the side for more than a minute.
Press "OK" to activate the filter. The coffee machine delivers hot water, then stops automatically.
The filter is now active and you can use the coffee machine.
