My Pond Pump Stopped Working

If your pond pump stopped working the first thing to do is try plugging it into a different GFI outlet using a extension cord. If that outlet also trips than you know the pump is broken and needs to be replaced. Many times the GFI outlets in outdoor situations will fail, this is a low cost item that can be found at a hardware store. If the outlet doesn’t respond to pressing the “test” and “reset” buttons, the receptacle needs to be replaced. If you are not using a GFI outlet for your pump and it stopped working, check the circuit breaker inside your home. When you plug your pump in listen for a hum sound coming from the pump to help determine if the pump is getting power. This hum noise generally indicates that the pump is trying to spin the impeller but it cannot because it is jammed.

With the pump unplugged, clean the pump intake screens and impeller also look for a larger pieces of debris such a mulch or pine straw that might be jamming up or intwined in the impeller. Make sure the impeller can spin freely by moving it with your finger while the pump is unplugged.

Koi pond pumps need to be completely submerged in water. If your pump is over heating it may turn on and off every 10-15 minutes. If this is the case, refill you pond to the proper level and make sure there is nothing restricting water flow from getting to the pump area.

If your pond pump is connected to a check valve or other tubing that leads to a waterfall area you may want to disconnect it from that piping and just try running it in the pond to see what happens. If it pumps water not attached to any piping, take a close look at your plumbing such as check valves to make sure there are no blockages.

Pond pumps typically last 4-7 years. The pumps that we select and install for you include 3 year warranty. Much improvements have been made to koi pond pumps in recent years, a new pump will likely save you a lot of money on electrical costs.

Other Electrical notes:
  • It is required that a ground fault circuit interrupter (GFCI) be installed for the water feature by a qualified electrician following local and national codes.
  • It is recommended that a dedicated outlet be provided for the water feature.
  • Please have the electrician refer to the pumps electrical specifications for the proper electrical operating range of the pump.
  • The pump will need to be run within these electrical parameters to ensure proper pump performance and best possible lifespan.
  • Electrical testing should also be completed under full load at the outlet. Make sure all other electrical devices that will be in used in and around the water feature are plugged in and in operation during full load testing phase. The pump should still fall within the minimum and maximum voltage and ideal amperage range during full load testing.
  • Hardwiring the pumps is not recommended due to complications caused when servicing or replacing the pump.
  • Power outlets should be at least one foot off the ground to prevent rainwater from getting into the outlets.
  • Paradise Ponds and Waterfalls are not licensed electricians, therefore, we cannot perform any electrical work for your pond.
