The water heater shows "E4" as a high temperature alarm and a "dry burn" warning. The reason is that the surface of the temperature measuring probe is seriously scaled and the temperature measurement response is sluggish. The temperature of the heat exchange surface of the water heater is very high, and when the water flows through, there will be scale production and growth, and after a long time, there will be a lot of scale attached to the inner surface of the heat exchanger, which will accumulate over time, causing the hot water pipeline to be blocked, which will cause the hot water output to become smaller (the phenomenon of small water pressure) and the hot water output time to become longer.

The hot water outlet is equipped with a temperature sensor, which is the narrowest place in the waterway of the water heater, which is easy to accumulate scale, resulting in temperature sensing lag, resulting in hot water overheating, causing overheating protection.
