If your welldana D36-140020 Inverter Pool Pump is not starting up, there are several potential causes that you can check:
1. **Power Supply**: Ensure that the power supply is connected and functioning properly. Check for any blown fuses or thermal overload issues.
2. **Motor Shaft**: Verify that the motor shaft rotates freely without any obstructions. If the pump has been idle for a long time, manually rotate the motor rear shaft a few times with a screwdriver.
3. **Priming**: Make sure the pump/strainer housing is filled with water and the O-ring of the cover is clean. Ensure there are no loose connections on the suction side and that the strainer basket is not loaded with debris.
4. **Suction Side**: Check for any clogs or obstructions on the suction side of the pump.
5. **Water Level**: Ensure that the water level in the pool is adequate for proper pump operation.
If after checking these steps the pump still does not start, it may be necessary to contact the supplier for further assistance or repair.
