I noticed that the water feature height was really low when it should be high, so I decided to do some checking. There was no flow from the return jets. I thought maybe our pool technician had selected an incorrect program, so I cycled the power. The motor started, but during the priming at the beginning, it seemed like it was running at a low rpm based on the noise and from what I could see through the strainer lid. My guesses are that it is due to a blockage or air leak somewhere. What are your thoughts on where I should start and the order?
1. Replace strainer lid o-ring
2. Check pool filter cartridge for debris or damage. Just replaced in October of last year.
3. Replace body o-ring on filter
4. Check impeller. I think I will have to disconnect and uninstall the entire motor for this, so I figured it would be last.
Does anyone know of anything else I should add to the list or if I should change the order? It is unlikely, but I also need to rule out that someone did not unscrew the cover and reset the schedule set pins. I also need to confirm that the pump turns off at the right time to make sure that it isn't a motor drive issue.
Thanks!
