How do I get the water out of the flushing tank when the flush doesn’t work?

To remove water from the flushing tank of a Dometic CT 4050 when the flush is not working, follow these steps:

1. Drain the freshwater tank completely.
2. Drain the water supply system fully.
3. Operate the flush button until no more water is in the pipes (if possible).
4. If the flush button does not work, manually disconnect or drain the water line connected to the flush system.
5. Ensure the cassette tank is emptied and rinsed.
6. Let the drain pipe remain open to allow the tank to dry.

These steps help prevent damage and remove remaining water even if the flush is not functioning.
