If there is water running under the car despite everything being closed, it can be that there is still a valve open:
- Make sure the fresh water tank drain is closed
- Make sure the waste water tank drain is closed
-
Check the valves under the floor close to the bathroom:
-
Check, if the cold protection valve is closed. It is located under the seat in the passenger area. Lift the seat cushion:
The cold protection (or anti freeze) valve automatically drains the boiler when there is a risk of frost. This prevents the drain from freezing.
The system measures the temperature inside the van. As soon as it is around 3 degrees or lower the system is activated and lets all the water that was in the boiler and the fresh water tank out. To deactivate the system, the room temperature has to be a least 7 degrees, otherwise the blue button will jump out again.
To ensure that the water supply continues to function and the valve is switched on, the blue lever must be turned clockwise and then the blue button must be pressed in.
