The Siemens water filters can be installed only cumbersome. Whether it if you think you have now done everything right, even to the exchange remains in this position or float again when refilling of water, is by no means assured. The idea as such is good and the water softener works, as I know from normal Britta- water filters. If you already use filtered water for the filling of the water tank of the fully automatic espresso machine, then you can delay immensely depending on the water hardness, the de-scaling program. What is not at all are the prices that are charged for a water filter.
