    Water Sensor Shortage

    I have a Hayward Salt Machine (Smart Control 2) and I am getting a reading that says "Water Sensor Shortage". How do I repair that? Currently the machine will not read the temp of the water but is still giving my salt level.

    Re: Water Sensor Shortage

    Thereís a temperature sensor in the plumbing somewhere. Most likely it has failed.

    The part you need is probably the Hayward GLX-PC-12-KIT 10K Thermistor Temperature Sensor. Find it in the plumbing and follow it into the automation box.

    Turn off power to the system and disconnect the two wires. Test resistance through the sensor and compare ohms to temperature in 10 K thermistor chart.

    If ohms donít match temperature, replace sensor.

    Donít do anything that youíre not sure that you can do safely.
