After prolonged use of the water pump, various malfunctions may gradually become apparent. One of the more common problems is that the water pump motor makes a buzzing sound, but the impeller stops rotating. Faced with this situation, many users may feel confused and unclear about the specific cause of the malfunction. Next, we will analyze the potential root causes of this phenomenon. For detailed information, please refer to the following text:
If the water pump produces a buzzing sound while the impeller does not rotate, it usually indicates that the motor itself is not in serious condition, and the problem may lie in the head transmission system. The bearing may be damaged or stuck by foreign objects. In the power-off state, you can try manually rotating the fan blades for inspection; If it cannot be rotated, the problem can be basically determined.
Once the impeller is found to be stuck, avoid starting the water pump for a long time to prevent the motor from burning out. Users can try to lift the water pump out of the water surface for no-load operation, or manually turn the impeller. If the impeller still does not rotate and there are no obvious abnormalities in appearance, it is likely that the bearing is stuck or damaged. At this point, it is necessary to solve the problem of jamming or replace the bearing.
It should be noted that there are various reasons that can cause the water pump to buzz but the impeller to not rotate. Users can conduct preliminary troubleshooting according to the above methods. If the problem does not match the above reasons, it is recommended to contact the manufacturer in a timely manner for professional assistance.
