If your jug rinse nozzle starts spraying without a jug being pressed down, it is usually a sign that the jug rinse sensor inside the inductor is failing or providing a "false positive" signal.
The jug rinse sensor is located in the "heart" of the inductor, where it is exposed to high-pressure water and a wide variety of concentrated chemicals.
Chemical Exposure: While we use high-quality, chemical-resistant components, some aggressive products can eventually work their way past the seals over time.
The Result: If moisture or chemical residue gets inside the sensor housing, it can create an internal short that makes the system "think" a jug is being held down, triggering the rinse cycle unexpectedly.
Because this is a hardware issue, the sensor typically needs to be replaced to restore reliable operation.
Temporary Workaround: If you are in the middle of a field, you may need to manually close the water supply valve to the inductor rinse to prevent it from spraying until the sensor can be replaced.
