Q: The pump isn’t working. The LED light will turn on, the system is charging but the pump isn’t working. I did the trouble shooting of cleaning the pump and tried to test it as best as I can. From what I can tell there’s a slight humming coming from the pump - as if it’s receiving a tiny bit of power but not enough to get it going.

A: Please check if the impeller magnet is blocked by sands or any other debris. If so, please clean it and wash the cover of the pump impeller as well.
