Reasons and Solutions for Solar Booster Pump Not Rotating

The solar booster pump is an important part of the solar water heater system. It can lift water from the solar collector to a high level to provide hot water supply for households. However, sometimes we encounter the problem that the solar booster pump does not rotate. This article will explore the reasons and provide corresponding solutions.

Reasons and solutions for solar booster pump not rotating
When the solar booster pump does not rotate, we need to first determine the cause of the problem so that we can take appropriate solutions. Here are some possible causes and their solutions:

Power supply problem:
The solar booster pump requires electricity to drive. If the power supply fails or the plug is loose, the water pump will not work properly. The solution is to check whether the power line is properly connected and make sure the plug is securely inserted into the socket.

Insufficient water level:
Water level in the solar collector that is too low may prevent the booster pump from starting. When the water level falls below the set threshold, the water pump will automatically shut down to prevent dry burning. The solution is to check the water level in the collector tank to make sure it reaches the appropriate height.

Control circuit failure:
Solar booster pumps are usually controlled by a control circuit. If the control circuit fails, the water pump will not be able to receive the start signal. The solution is to check whether the control circuit is working properly. If necessary, contact professional technicians for inspection and repair.

Water pump failure:
The water pump itself may malfunction, such as the blades are stuck, the motor is damaged, etc., resulting in the inability to rotate. The solution is to replace the damaged water pump or ask a professional to repair and adjust it.

Summary: 
The failure of the solar booster pump to rotate may be caused by power problems, insufficient water level, control circuit failure or water pump failure. We can solve these problems by checking the power circuit, the water level in the collector tank, the control circuit and replacing the water pump. If you encounter complex problems, it is recommended to seek help from professional technicians in time to ensure the normal operation of the system.
