The heating rod trips, mainly due to the following reasons
There is no water in the water tank or the water level does not meet the conditions starting. If you start the heating rod at this time. time, it will turn off automatically, as you said, the pipeline is frozen and blocked, preventing water from entering, or the water entering slowly, so that the water in the water tank will not is not sufficient to start the electric heating
There is a leak in the heating rod, causing a short circuit, causing the heating rod to trip and stop
If the pipes are frozen, it is recommended to turn on the defrost function of the heating belt. Since the temperature has dropped sharply in recent days and there has been continuous cloudy weather, it is recommended to keep the heating belt powered on to protect the pipes from freezing and blocking, ensuring uno fluid circulation of pipes. If the electric heating rod is leaking, you need to be careful. Although it has a protective function, it is very dangerous to be charged in water. It is recommended to use a test pen to test it. be sure to replace the electric heating rod.
Two possibilities: Firstly, because the water temperature of the solar water heater has reached 70 degrees, the meter currently has a function self-protection. , even if you press the electric heating button, it will jump because the predetermined heat has been reached and no electric heating is needed.
Second, the electric heater is broken. The instrument has a self-protection function. . If there is a problem with the electric heating, the relay will trip directly.
