Can I fix Hayward code No Flow myself?

Start with these safe checks: Check the pump is running, the baskets and filter are clean, and valves to the cell are open. If flow is good and No Flow stays on, have the flow switch checked.

When should I call a technician for code No Flow?

If flow is good and No Flow stays on, have the flow switch checked. Water and electricity together can kill. Turn the equipment off at the breaker before you open anything, never touch equipment while standing in water, and stay out of the pool or spa if you feel tingling or suspect an electrical problem. Leave wiring, boards and GFCI faults to a licensed electrician or service tech.
