Roidme Eva 2023 clean water tank error - Solved!!!

The culprit was that the pump had an air bubble inside, and it couldn't start to pull water on its own. Solution was to fill up a syringe with water, and start to inject it with light pressure in the clean water tank inlet tube, during a running water change cycle. Needed around 10 additional water change cycles to run down, before it stopped to show the fill clean water error, probably it took this time for all the air to exit the system.
