Water sensor kit for all TrueSteam models. Includes the sensor, wire harness, 2 gaskets, retaining clip and screw. This sensor has five terminals that connect with the harness's modular connector. The terminals are non-magnetic stainless steel bars that protrude out the bottom of the assembly at different levels. This is a simple device with no internal electronics. Continuity should exist between the terminal connection and where the stainless steel protrudes from the bottom. Continuity should not exist between the different terminals (when dry).
