TROUBLESHOOTING  

If the pump fails to operate: 

 

Check to make sure the power cord is plugged in, the pump is getting power and the pump is 
fully submerged. 

 

Check the pump outlet and any tubing, fountains, spitters etc. for kinks or obstructions. 

 

Remove the front cover and/or pump cover, and impeller cover to expose the impeller. Turn the 
impeller to ensure that it is not broken or jammed.

Check to make sure the pump is completely submerged in water. 

 

Check to make sure the impeller, water sensor and the housing are clean.
