Haier solar water heater can't get water. What happened when the screen turned black after pressing the water button?

It's also your fault that my solar water heater controller can watch the weather. The screen is normal when water is not added, and the black screen crashes when water is added manually or automatically. It can be displayed normally after restarting. I studied it for a long time, but I couldn't find the reason. Has your controller problem been solved now?
