Unidentified Things in the Water

There are reports from the Stockholm archipelago, that there might be foreign submarines travelling under Swedish territorial water. I am more concerned with another kind of unidentified things in the water. Our dish washer does not work as it should. We believe there might have been something in the water from our well, clogging the pipe bringing water to the dish washer. Our water is normally very clean, but the dish washer does not seem to get water enough to wash the dishes. We have to wash everything by paw for the moment. This is not difficult at all, but it takes a little more time, hence in is a little annoying. I wonder how we can make the dish washer operate as it is supposed to again.
