If you suspect that water has gotten into a cable connection or into
the plug connection of a submersible sensor, disconnect the cable
and allow the parts of the sensor to sit in a warm place for 24
hours. If water in the connector is the problem, it should dry out
sufficiently to allow normal sensor operation.
