The water level shows incorrect data

[home409ca]

I did everything according to the instructions.
It was working fine for a few days, but then the water sensor readings started showing strange data - even though the humidifier was untouched, and no water was being added.

What could be the reason?
How can I fix this?

Thanks

Did you tried to clean sensor? I open it and it was mess inside because of which data can be corrupted.
