I had an issue with my fresh water level indicator (T6.1) where the control panel continuously indicated empty, regardless of the actual level. Sometimes the tap would work, sometimes it wouldn't. Had a look today in the tank under de wardrobe and removed the float/senor. Turns out the pump was installed incorrectly, able to move around freely and stopping the float from moving up with the water level. Moved it to the corner where there are 2 tabs holding it in position and out of the way of the floater. Works perfectly now. I have attached a picture of where/how it should be installed. Hope it helps for those strugling with the same issue.
