How to Troubleshoot an Onga Pool Pump

By Megan Martin
Swimming pool pumps work to keep water flowing.

Onga swimming pool and spa pumps help keep water flowing in your pool. While Onga pumps generally require little maintenance on an everyday basis, it is important to know what you should do if a problem occurs. Learning to troubleshoot an Onga pump can help you save money on service calls.

Troubleshooting a Non-Functioning Onga Pump

Test the outlet the pump is plugged into by plugging in another working appliance to see whether it will work. Check the fuse box and circuit breaker. Replace any blown fuses and reset the circuit if necessary.

Turn off the pump and let it to cool down. If the pump has overheated, the unit probably has turned itself off. Turn the pump back on to check whether it works.

Place the pump in an area with sufficient ventilation. Check the pump, including the suction strainer for any debris and remove it if necessary. The motor shaft should spin easily. The voltage supply should be sufficient for the voltage listed on the pump's voltage plate. If the pump will still not operate, call a professional for help.

Troubleshooting Reduced Water Flow

Measure the water level. The water level must cover at least the bottom half of the skimmer for the pump to function. Add more water if necessary.

Check that the valves are correctly positioned. The valves should be turned to the open position. Check the valves on the suction or discharge of the pump.

Search for air leaks in the suction pipes or fittings. Close the hair and lint pot to keep it free of leaves and other debris. Check the underside of the pump or casing for any leaks.

Look for items that may be blocking or obstructing the pump. Check both the suction and discharge areas for debris or other blockages. Remove them if necessary.

Prime the pump again. Turn off the power to the pump. Release all air from the filter, piping system and pump. If the water source is higher than the pump level, the pump will prime itself. If not, disconnect the power supply, remove the lint and hair pot and fill the casing bowl up with water. Clean and lubricate the "O" ring and replace it. If water flow does not restore, call a professional.

Troubleshooting a Leaky Pump

Turn off the pump. Loosen the casing bolts with a wrench.

Examine the "O" ring beneath the bolts for proper alignment. Look for any indications of wear and tear. If the ring is worn or otherwise damaged, or if the pump continues to leak, replace the "O" ring.

Replace the mechanical or lip seal if they are worn or damaged. Tighten the casing bolts. If the leak continues, contact a qualified service professional.
