When the filler valve has been opened, the water flows through the
flow sensor towards the integrated inlet via a free flow channel and
into the regeneration chamber. When the regeneration chamber has
been filled, the water flows through the water softening system via the
overflow channel and then flows as soft water into the pump sump.
When the electronics module has detected the prefill level via the flow
sensor, the circulation pump switches on and is filled up to the wash
level.
The water volume of completed rinse cycles is recorded by the
electronics counter which determines when the water softener
requires regeneration. Before each regeneration step the electronics
check whether the capacity of the water softener is adequate for
a complete "Normal Programme Sequence". If not, regeneration
starts.
The water softening system is regenerated and rinsed through during
the wash cycle. The regeneration valve
is opened for this purpose. The stored volume of water flows into the
salt dispenser via the valve, absorbs salt and flows as saline solution
through the water softening system into the pump sump. Rinsing takes
place in three stages, each with one calculated volume of water.
