Check the voltage
You should ensure the voltage is at +/- 10% of the ratings of the motor. You need to check that the system is getting sufficient power by reading voltage at the control box, pressure switch and at any other components that electricity is running through. If you discover that power is too low or too high then you need to contact pump repairs professionals.
Check the pressure switch
The pressure switch should be examined for any wear and defects. Look for burned or melted components, deformation, or a lot of blackness.

Check the tube leading to the switch for any debris or sediments. Check that the contacts are closing and opening properly by turning on the system.
Check the control panel

Check splice connections
Check whether the splice connections have corroded and signs of power not getting in. if you realize that power is not getting in, contact submersible pump repair in NZ.
