How to repair the Yuhe energy saving CNC commercial water boiler when it is good and bad

Repair precautions.

1.Do not install the water boiler in a humid environment, such as a bathroom. Because the air in the bathroom is humid, after the water vapor enters the electrical box, it is easy to condense on the surface of the insulating medium, reducing its insulation performance and causing leakage accidents.

2.When using the water boiler, it should be filled with water before turning on the power supply, and do not adjust the thermostat by yourself to prevent the thermostat from being adjusted above the boiling point temperature.

3.During use, do not easily remove the grounding wire of the water boiler, because the grounding measure is the last protective measure to prevent electric shock.

4.It is necessary to check the inlet water source of the water boiler frequently to prevent the water inlet from being blocked and avoid the occurrence of dry burning of the electric heating pipe.

5.Descale regularly. If the local water quality is poor, a water purifier can be installed at the water inlet of the water boiler to improve the work efficiency of the water boiler, prolong the service life, and ensure the cleanliness and hygiene of drinking water.

6.Before maintaining and cleaning the water boiler, the water source and power supply of the water boiler must be cut off. When cleaning the shell of the water boiler, it should be wiped with a clean rag, and it is strictly forbidden to rinse the shell and electrical box with a jet of water.

If it can't be repaired during the warranty period, it can be replaced free of charge

1. The wrong line is connected.

2. The power control board is faulty.

3. The CNC display board is faulty.

Hello! How much does this water heater motherboard cost?

Fourth, there are many professional forums and knowledge platforms on the Internet, and there are also a lot of information on them, and I always go to the forum to seek solutions to professional problems.

Fifth, ask your questions more carefully and clearly! It's easier for people to understand what it means!

Thanks for taking my suggestion! !

Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction, and the function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into two types: measuring physical size and mechanical displacement. According to the different forms of the variable to be measured, the displacement sensor can be divided into two types: analog and digital.

The analog type can be divided into two types: physical type and structural type. Most of the commonly used displacement sensors are analog structural types, including potentiometer displacement sensors, inductive displacement sensors, self-leveling machines, capacitive displacement sensors, eddy current displacement sensors, Hall displacement sensors, etc. An important advantage of digital displacement sensors is that they facilitate the direct feeding of signals into the computer system.

These sensors are developing rapidly and are becoming more and more widely used.
