The circuit board of the tea bar machine is used to transmit user instructions and control the operation of functions. Therefore, if the circuit board fails, all functions of the tea bar machine will basically fail to operate, including the switch. Users need to ask professionals to replace the appropriate circuit board. Because the circuit board is complex and the maintenance cost is high, once it is damaged, the maintenance personnel will suggest replacing the tea bar machine directly.
How to choose a tea bar machine
1, choose a style. When choosing a tea bar machine, you should pay attention to the style of the tea bar machine, which is generally divided into horizontal and vertical. It is suggested to choose vertical, which is not only beautiful in appearance, but also healthier and safer than traditional drinking fountains. Can reach the boiling water temperature, built-in bucket, can prevent water pollution, let us drink better water.
2. Select the function. When choosing a tea bar machine, we should also pay attention to its function. For example, when choosing a constant temperature health pot or a heating pot, it depends on whether the material is environmentally friendly; See if there is temperature control and whether the temperature display screen has the function of displaying temperature in real time to meet people's different drinking water needs. In addition, it depends on whether there is water that can be left unattended, which can save time and not waste water.
3. Heating mode. In addition to choosing styles, we should also pay attention to the heating method. The traditional kettle will be heated repeatedly, which will destroy the molecules in the water and affect health. Therefore, choose a tea bar machine with a complete heating system, which is isolated from the air when heating and will not be heated repeatedly. Meanwhile, the sterilization effect is good, and people can drink fresh water.
