The most likely cause is an ultra high temperature alarm. Because the sun is strong in summer and the temperature has reached 90° for several days in a row, there is no need to worry about this situation. there is water in the water tank and the exhaust hole on the water tank is not clogged, everything will be fine! If you are using electric heating, you must stop immediately!

Recommended: ""Dr Sun" Solar power (Class 1 energy efficiency, 3C certification), Sancang solar power (no need for water level sensor probes or 'solenoid valves), the utilization rates of heating and hot water are fast in rainy days, and the after-sales rate is also greatly reduced, saving both time and energy.e. Ordinary single storage solar heating only takes 20-30 minutes without sunlight, while single storage heating takes 2-3 hours! be an ultra-high temperature alarm, because the water tank The water temperature is too high. In order to prevent the vacuum tube from bursting due to cold water, this function is provided, but other reasons cannot be ruled out. For more details, please. Consult the instrument's instruction manual provided or ask the buyer. The water pressure is too low and the water tank temperature is too high.
2. Check the tap water pressure. automatically, check whether the solenoid valve can open automatically. If there is a problem with the adjustment, check if the pipe is blocked
3. the collecting tube and the reflecting plate; the vacuum collector tube leaks and loses vacuum; the heat pipe breaks down, the weather is bad, the energy of solar radiation isinsufficient and the water valve is not closed tightly, slowly; water filling or draining status. Wipe the dust on the surface of the vacuum collector tube and reflector, remove the obstruction; replace the vacuum collection tube; use an electric auxiliary heater; p>
Detailed information:
1. It is strictly prohibited to spray water on electrical parts when taking a bath, especially when using a bathroom heater. It is strictly forbidden to operate the electrical parts with wet hands. The auxiliary heating system and the antifreeze belt must be turned off. It is strictly prohibited to use the leakage protection cap as a switch. It is strictly forbidden to frequently start the electrical parts.
2. It is strictly prohibited to use solar water heaters duringthunderstorms and windy weather.
It is strictly prohibited to use solar water heaters during thunderstorms to avoid electric shock. working principle, solar water heaters should be installed on the upper balcony. Solar water heaters generally require large volumes due to heat collection. Therefore, users should pay attention to reinforcing the supports of solar water heaters in windy weather to avoid this. be sure to fill the water heater with water on windy days to increase stability.
3. Scientifically choose the water supply time
Solar water heaters need to be filled with water regularly, but. when the weather is particularly hot, it is strictly prohibited to add water when the water temperature is extremely high, and it is strictly prohibited to add water immediately after running out of water.At. Because the sunlight is strong in summer, the sun's temperature. The vacuum tube in the air reaches 270 degrees Celsius to 400 degrees Celsius. At that time, filling with water can easily cause the vacuum tube to burst.
It is best to do it the morning before. sunrise or two hours after sunset in the evening. Water supply, this can guarantee the life of the solar vacuum tube.
