What was the time frame between when it fell in the water and when you "... had a go at taking it apart, drying it out properly etc"? Also what did "...properly etc" entail?
''The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away.''
The longer it is left without being cleaned properly, the worse it will be, especially if the battery is still connected to the systemboard and if the phone has been charged or tried to be turned on before it is cleaned
Did you disassemble the phone and clean ''all the affected parts'' using Isopropyl Alcohol 99%***+*** (available at electronics parts stores) to remove all traces of corrosion?
If not perhaps you should check the boards, under any shields that may be covering components, flex cable ends and connectors again for any trace of corrosion or component damage.

Here's an image of the Power On troubleshooting flowchart from the [https://phonelumi.com/samsung-galaxy-s10e-sm-g970-schematics/|service manual] that shows what to do. The manual also has the board layout so that you can find all the components mentioned in the flowchart.
