The blade section on the Impeller (the blue section) should only turn 180° in relation to the magnet. If it spins freely or at all, the Impeller should be replaced.

Check the Impeller Shaft, it should wear very little but can break. Check both End Caps are present and undamaged. To test the electric coil in the Pump Head, remove the Impeller. Plug the Pump Head in (ensure everything is dry first) and hold the Impeller magnet next to the Pump Head as shown. You should feel the magnet vibrate.

Put the Impeller Shaft through the Impeller and hold the assembly by the Impeller Shaft ends. Spin the Impeller on the Impeller Shaft. It should spin smoothly - if it wobbles, the Impeller may be worn and need replacement.

Check both the Impeller Magnet and the inside of the Impeller Well for damage. The surfaces should feel smooth. If not, they are damaged, and the pump will not work at full capacity. The damaged part will need to be replaced.
