Troubleshooting
Pump loses prime or has air in the basket
Possible Causes
- Worn or dry lid o-ring
- Air leak on the suction side (unions, drain plugs, valves)
- Low water level
How to Fix
Check the lid o-ring and seat it clean, tighten suction unions and drain plugs, and bring the water to mid-skimmer.
Water leaking between the motor and the pump
Possible Causes
- Worn mechanical shaft seal
How to Fix
Replace the shaft seal (356210S) before the leak rusts the motor bearings.
ON/STOP light blinking red
Possible Causes
- An alarm has stopped the pump — e.g. Priming Failure, Overheat, Over Current, Over/Under Voltage
How to Fix
Read the code in the Pentair Pool app, the automation or the touchscreen, and fix that cause. A blinking green/yellow light is a warning only.
