No Flow: Led Flashing Or On - Hayward AquaRite series Troubleshooting Manual

3. No Flow: LED flashing or ON

The "No Flow" LED indicates that the flow switch is not reporting consistent flow.
When the pump initially turns on, this LED should flash for 10-60 seconds while the
system verifies consistent flow.
Pump Running & Valves are Set? Verify 12" of Straight Pipe
Step 3A
Step 3B
Verify the pump is running & valves are positioned so It is recommended for the flow switch to have 12" of
the flow switch is receiving water. IF the pump is not straight pipe preceding it (the TurboCell counts as
ON or the valve are not correctly set, resolve that first, straight pipe). IF not, consider moving the flow switch.
then recheck. IF correct go to step 3B. IF correct go to step 3C.
NOTE: The flow switch requires a minimum flow rate of 11GPM in order to properly engage. If using
a variable speed pump and the No Flow LED appears, try increasing the pump run speed to ensure
the flow rate is not causing the problem.
