Troubleshooting

Pump not running

Ensure the power cable is securely plugged in and the outlet is functional. Verify the pump is fully submerged in water. Check the intake for any blockages.

Reduced water flow

Clean the pump's intake screen and impeller area. Check the connected tubing for kinks or obstructions. Ensure the flow rate adjustment is set correctly.

Pump is noisy

Confirm the pump is securely mounted and not vibrating against any surfaces. Ensure the impeller is clean and free of debris. Check that the pump is fully submerged.

Water level too high for desired flow

The pump's performance is dependent on head height. If the water level difference is close to the maximum 60cm, the flow rate will be significantly reduced. Consider relocating the pump or adjusting the system.
