The “No Flow” light indicates that the flow switch is not detecting sufficient water passing through. Check the following: cleaning the cell or the filter (see how to backwash a DE Filter or Clean a Cartridge Filter). Replace the flow sensor.
Moreover, how do you test a Hayward flow switch?
You can test the continuity of the flow switch using a Voltmeter or Ohmmeter. Continuity is open if there is no flow. Alternatively, continuity is close if sufficient water flow is detected.
Pump lid o-ring is a good fit, in good condition, and lubricated. Pump lid cover is Tight (really tight). Impeller is not clogged with small debris. Check that pump basket is not broken or misaligned.
In this regard, how do you fix a no flow pool pump?
If your pump looks like there is no water in it, turn it off and unscrew the pump lid without losing the o ring. Fill up a bucket with pool water and pour it into the pump, this is called priming. Once the water level reaches the top, replace the pump lid with the o ring and turn your pump back on.
How do you bleed the air out of a Hayward pool pump?
Why is there air in my pool pump?
Air bubbles in your pool mean that air is being sucked into the line on the suction side of the pump. It’s likely happening because of one of these issues: The pool water level is too low. The strainer pot lid isn’t on tight or its O-ring is loose/absent/compromised.
What happens if air gets in pool pump?
If the pool pump is sucking air, then it may lose its priming. The pool pump can also overheat or cavitate. This is more common with in-ground pools. The function of a pool pump in in-ground pools is to pull water and distribute it through pool equipment into the pool.
