I have a Pentair IntelliFloXF VSF Pump (022056) that was installed about 4 months back for a new pool build. Since start up, I have always used the flow reading and found it to be accurate. Today, I decided to clean the pump's filter basket by flipping the breaker, cleaning the basket, and turning it back on. After turning the pump back on, it always primes itself at max RPM and then drops back to normal rates. After doing so today, the flow rate is now way off. Despite having the pump set to 40 GPM, the RPM and Watt readings are both low. Also, the flow warning for my SWC was blinking letting me know it wasn't receiving enough flow.
I've mitigated the issue by manually setting an RPM instead of a flow. Could an air bubble or something else in the pump be causing the flow reading to be off?
