If water leaks from under the vehicle, this can have various causes:
- Check that the levers of both tanks are closed.
- The cold protection valve may be open. It is located behind the flap on the side under the rear seats:
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.
- It is also possible that the valves of the boiler are open by mistake. There are three of them. Turn them clockwise to close them.
You will find two in the left cupboard under the bed. You can see them under a flap on the floor:
And another boiler valve is hidden behind the flap on the side under the rear seats, behind the cold protection valve:
