Omni-Flow sensor error.

[Supersix]

I get a "No Water Flow" message when my pool starts in the morning. In the past, I would receive a notification after the water flow issue was resolved. However, it simply shows "No Water Flow," even though the pool turns on and water comes from the jets. This has been happening for over a month. I rebooted it three times, but it didn't fix the problem. Also, I received an error email notification at 2:30 am this morning. My pool sits idle and doesn't fire until 10am. It's a new build that's two years old—Hayward equipment.

Maybe a bad flow sensor.

As JamesW pointed out, it could be a bad flow switch. Also, check the wiring from the switch to the panel. It is possible that it is damaged. Small "critter" like to chew on the insulation (it apparently tastes good to them) and will sometimes cut through the wire itself, or the wire has been exposed and it will eventually break or short-circuit.
In certain more rural areas locally, I have had to run that wire, and temp sensor wire, in PVC conduit to stop the problem.
