The solar water tank is not full, but the overflow port of the water tank is leaking. Why?

Leaking from the overflow port of the water tank means that the water in the water tank has been filled up.

If the wired controller shows that the water level is not full, it is most likely that the water level sensor in the water tank has failed, causing an incorrect water level signal to be transmitted.

It is recommended that when the water heater is filled with water, if the water level shows that it is not full but has begun to overflow, it is considered that the water has been filled.
