Has your pond pump GFI stopped working? GFI outlets and circuits breakers protect people from electrical shock. If the GFI detects an energy leak of even a thousandth of a milliamp, it will shut down the circuit. The easiest way to try and fix the problem is to push the reset button on the GFI. If the outlet doesn’t respond to pressing the “test” and “reset” buttons, the receptacle might need to be replaced.

If you are not using a GFI outlet for your pump and it stopped working, check the circuit breaker on your main electrical panel. When you plug your pump in listen for a humming sound coming from the pump to help determine if the pump is getting power. This humming noise indicates that the pump is trying to spin the impeller, but it cannot because it is jammed.

User Manual for testing GFCI Outlet

If your pond plumbing has restricted (undersized pipe size) it is possible the pump is straining and could set off the GFI

You can test this by simply placeing the pump in the pond, not connected to any of the plumbing and see If it pumps water. Take a close look at your plumbing such as check valves to make sure there are no blockages.

Most submersible pond pumps typically last 4-7 years while an external pump may last 10 years or more. Many improvements have been made to koi pond pumps in recent years, so it possible a water pump will save you some monthly operating costs.

If you have tried all these steps and still cannot get your GFI working, please reach out to us and we will be happy to help.
