It takes multiple aspects to determine whether the Smart Washing Machine Main And Secondary Boards need to be replaced.
First, observe the operating status of the washing machine. If the washing machine frequently displays fault codes, and these fault codes are related to the main and secondary boards, such as the motor cannot start normally, drainage is abnormal, and the program cannot run normally, it may mean that there is a problem with the main and secondary boards. Especially when the same fault occurs repeatedly and cannot be solved after simple cleaning, adjustment and other routine treatments, it is necessary to consider whether the main and secondary boards are damaged.
Secondly, check the functional performance of the washing machine. If some special functions of the smart washing machine suddenly fail, such as the intelligent control function cannot be used normally, the mobile phone APP cannot be connected for remote operation, and different washing modes cannot be switched, it may be that some parts of the main and secondary boards are faulty. At the same time, if the washing machine has abnormal noise and vibration during operation, it may also be caused by abnormal operation of the main and secondary board control motor and other components.
In addition, check the appearance of the main and secondary boards. Open the back cover of the washing machine and check whether there are obvious signs of burning, capacitor bulging, component shedding, etc. on the main and secondary boards. If you find that the main and secondary boards have a burning smell, or see obvious physical damage, then it is likely that the main and secondary boards need to be replaced.
In addition, you can use professional testing tools to test. Some maintenance personnel will use tools such as multimeters to test whether the circuits on the main and secondary boards are unobstructed and the voltage is normal. If the test results show that some circuits on the main and secondary boards are open, short-circuited, or the voltage is abnormal, then you need to consider replacing the main and secondary boards.
You can also refer to the age of the washing machine. If the washing machine has been used for a long time and exceeds the general service life of the main and secondary boards, then even if there are no obvious signs of failure, the performance of the main and secondary boards may be degraded due to aging of components, etc., and you need to consider replacing them.
In short, judging whether the Smart Washing Machine Main And Secondary Boards need to be replaced requires a comprehensive consideration of multiple factors such as the operating status, functional performance, appearance inspection, professional testing, and service life of the washing machine. If you have any questions about whether the main and secondary boards need to be replaced, it is best to consult a professional maintenance personnel to ensure that the correct judgment and decision are made.
