Fill JURA S95 system

Good day, I have since yesterday the following problem with my S95.

(Preliminary info: The machine was unused for a long time in the basement, system was also not drained).

Yesterday at the first start it was still possible for me to draw coffee through the machine normally. Probably via residual water in the system.

Today I had tried to decalcify the machine via the decalcification mode. Here came only a little water over the steam function. At some point, this has completely subsided. I then searched the system for blockages and at first glance found nothing. After a short research I found the possible cause 'clogged flowmeter'. I removed this and it was also clogged, so that no more water withdrawal was possible. After cleaning, the water is flowing again.

Only now the machine constantly wants to fill the system, here only water comes out of the tap. A filling can not be determined.

What can be the cause of this? Please brief feedback.

Thanks in advance!

Hoses incorrectly connected to the flowmeter.
It should have arrows on the hose connections.
The bottom is normally the one from the tank and the top is the one to the pump.
Is the connector plugged in correctly?
