Hello, I just want to ask what causes Arduino level sensor in my water indicator project the code is working but As soon as it gets wet, the value on the analog input goes almost all the way up. If there is any water residue on the sensor it remains that way. How to stop water from sitting between contacts ? Any tips how to solve this?

You could wipe it off or have a fan that will cause it to dry.

I tried wiped it off already but it seems that it sticks on its value example water level 0-5 mm still even if I put it away from the water
That is the best I can do with the information provided. A schematic, not a frizzy picture would help as well as links to technical information on the hardware items, azon links are useless. Also it would help to post your code. A picture of your setup might help as well.
I want to ask what causes Arduino level sensor in my project the code is working, all my connections is correct but as soon as it gets wet, the value on the analog input goes almost all the way up. If there is any water residue on the sensor it remains that way and doesn't go back to empty because of some residue even if I already wiped the sensor.Any tips how to stop water from sitting between contacts?
Post a link or a picture of your water level sensor.
You must identify your project for anyone to help make suggestions as to what the problem is.

Water level sensors with bare copper traces are just toys,
mainly to learn how to not sense rain or water levels.
Capacitive sensors (no bare copper) can be covered in a plastic film, so water beads and doesn't stick. The often also have a low-power heating element underneath.
