The pump should then resume normal operation.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | No power, water level too low, clogged intake, sensor malfunction. | Check power connection and GFCI. Ensure water level is above 1 inch. Clean intake screen. Perform Magnetic Induction Resetter procedure. |
| Pump runs but little to no water is discharged. | Clogged intake screen, kinked or blocked discharge hose, airlock. | Clean intake screen. Clear any obstructions in the hose. Briefly lift and lower the pump to release air. |
| Pump does not turn off. | Sensor malfunction, debris interfering with sensor. | Inspect sensor for debris and clean if necessary. Perform Magnetic Induction Resetter procedure. |
