Hi, I had the same problem and exchanged the capacitive sensor by an inductive sensor (less than 3$ on Aliexpress).
Capcitive sensors are sensitive to moisture and temperature, inductive sensor are not.
This worked perfect for me.
It is really an easy replacement (requires cutting and soldering 3 wires)
