My pump was working fine until yesterday. It stopped pumping water without any change.
Pump runs and there is a whirl action visible in the basket.
There is no pressure in the cartridge filter. No air comes out of the air bleed valve in the pressure gauge.
There is miniscule quantity of water flowing from the valve on the pump outlet. So it is not the filters possibly being clogged.
The strainer cover does not show water or air bubbling.
Troubleshooting steps I have taken include:
1- Cleaning the straining basket before the pump.
2- Tried various sources for inlet - spa, pool bottom, pool top, skimmer without any difference.
3- Tried various output options - spa, pool - no change.
