The electric water heater displays e1, which is mainly caused by a failure of the internal temperature of the water heater tank pipe. This is usually caused by too high a water temperature. If you encounter such a problem, you can lower the water temperature appropriately. When the water heater air pressure switch fails or the temperature sensor probe is damaged, it will cause the e1 solar system to fail. If there is a problem, check them one by one. Once it is determined which part is damaged, replace it directly.
This answer applies to water heater models from most brands such as Haier, Macro and Midea.
What is the problem when the solar water heater shows E1 and how to fix it?
There are two reasons why the solar water heater displays E1:
1. Because there is a problem with the signal line.
2. Terminalof the sensor is in poor contact.
You need to check whether the sensor terminals are connected correctly and whether the signal line is poorly connected or the signal line is broken.
Detailed information:
1. Solar water heater converts solar energy into thermal energy A. heating device that heats water from low temperature to high temperature to meet people's use of hot water in life and production.
2. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market. share.
3. Domestic vacuum tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other parts.are related. The conversion of solar energy into thermal energy mainly relies on vacuum heat collector tubes, which use hot water. to float and cold water to sink. According to the principle, the water will produce microcirculation to obtain the required hot water.

Hello, the common reason why the solar water heater shows E1 is: the sensor terminal is in poor contact or damaged and the sensor needs to be repaired.
Precautions for using solar water heaters:
1. The water stored in the solar water heater should be discharged regularly depending on the local water quality. Drain time can be selected in the morning when the sensor is relatively low.
2. Solar water heaters need to clean the inside of the vacuum tube for 2-3 years on average to avoider that the scale inside the vacuum tube affects the heat absorption effect.
3. If the solar water heater is equipped with special instruments, attention should be paid to lightning protection and electricity. Do not take a shower during thunder and unplug the electric heater.
