  • The connectors on the Flow Switch are attached to a PC Board connector that is located on the PC Board (usually at the top). There are other wires connected to this plug:

    • Jumper interlock wire, Flow Switch, High Limit sensor, and Temp sensor

    • Remove the pin connector from the board.

      • To remove a sensor or switch wire from the sensor harness connector, insert a paper clip into the slot corresponding with the wire to be removed. This will depress the pin tine, allowing the wire to be pulled from the harness connector.

  • Important! When reinstalling the sensor or switch wire back into the sensor harness connector, make sure the pin tine is lifted (approx. 1/32") prior to inserting the wire. This will ensure the sensor wire locks into the harness connector. Do not over bend the pin tine or it may break off.


  • A defective flow switch will cause a "Flashing Flo" or "Solid Flo" on the Control Panel Icon.

    • "Solid Flo" is the Flow Switch

    • "Flashing Flo" could be:

      • Flow Switch, Circulation Pump (clogged or defective), or Dirty Filter
