Troubleshooting steps for a submersible well pump:

Begin by prioritizing your safety. Before handling any electrical equipment, make sure to disconnect the power supply to the pump at the circuit breaker or control box.

Check the power supply to ensure that electricity is reaching the pump:

Examine the circuit breaker or fuse to see if it has tripped or blown. If it has broken or tripped, you need to reset the breaker or replace the fuse. Take a look at the wiring connections and ensure there are no signs of damage or loose connections.

Inspect the pressure switch, which controls when the pump turns on and off:

Verify that the pressure switch is functioning correctly. You can use a multimeter to test the continuity across the switch terminals when the pressure drops below the switch’s cut-in setting. If there is no continuity, it may be necessary to replace the switch.

Confirm that the well has an adequate water level:

Insufficient water level can prevent the pump from priming or cause it to run dry, potentially leading to damage. If you suspect a low water level, it is advisable to consult a professional well driller or water specialist for assistance.

Make sure the pump is properly primed:

If the pump fails to draw water into the system, it may not function correctly. Follow the instructions provided by the manufacturer to prime the pump effectively.

Inspect the motor wiring connections for any loose or damaged wires:

If the motor fails to start or trips the circuit breaker, there may be an issue with the motor. You can test the motor using a multimeter or seek help from a professional electrician to determine if the motor requires repair or replacement.

Check the pressure tank, which regulates water pressure and provides additional storage:

Examine the tank’s air pressure using a tire pressure gauge and ensure it is set according to the manufacturer’s specifications. If the pressure is too low or the tank is waterlogged, it can affect the pump’s performance.

Conduct a thorough inspection of the well pipe and wiring connections for any signs of damage or leaks

Damaged pipes or wiring can impact the pump’s performance. You needs to replace or repair any damaged components as soon as possible.

If you have followed these troubleshooting steps and are still experiencing issues with your submersible well pump, it is recommended to seek the assistance of a professional well pump technician or a licensed electrician who specializes in well pump systems. They possess the necessary expertise and tools to diagnose and repair complex pump problems.

Disclaimer: Please remember that working with electrical equipment and well systems can be hazardous. If you are uncertain or uncomfortable with any aspect of the troubleshooting process, it is best to seek professional help to ensure your safety and prevent any potential risks.
