today I had a wierd situation with my duo D 100.
After turning it off, it did the fresh water rinse like usual, but did not stop.
I checked for a leak (in the entire boat) but there is no leak and no open tap.
I closed the fresh water valve for the water maker, the rinsing stops.
I opened the valve, then the fresh water pump starts again (with rinsing).
During the process of making water there is no problem, the fresh water pump is not running.
Thus now I have to close the valve every time after using the water maker.
That is possible, but not like it should be.
Btw: If I open the fresh water valve for the water maker again (at least) 1 hour later, the pressure is (mostly) stable, no pump is running.
