I just de-winterized my 2019 Travato for the first time. All lines flushed out with city water hook-up. I wanted to fill the tank via tank fill with about a third a tank of water. I connected to tank fill vs. city water and ran water for 10 minutes. The gauge shows the tank fill is empty. Water did run underneath the unit while I was trying to fill the tank. The tank indeed was empty as when I flushed or ran sink water, there was no water. What could be the problem?
Thanks all!
