The normal operation of a smart washing machine is inseparable from the coordinated work of the main and secondary boards. When the washing machine is abnormal, judging whether the main and secondary boards are faulty is the key to solving the problem. The following are some methods to judge whether the Smart Washing Machine Main And Secondary Boards are faulty:
1. Observe the running status of the washing machine
First, you can preliminarily judge whether there is a problem with the main and secondary boards by observing the running status of the washing machine. If the washing machine cannot start at all, it may be that the main and secondary boards are not powered normally or the main control chip is faulty. If the washing machine suddenly stops during operation, or there is abnormal noise or vibration, it may also be that the main and secondary boards are faulty.
For example, when the washing machine suddenly stops during the washing process and there is no error prompt on the display, you can check whether the power supply is connected normally and whether the fuse on the main and secondary boards is blown. If the power supply and fuse are normal, it may be that the main control chip is faulty, causing the washing machine to be unable to continue to run.
2. Check the display of the display
The display of a smart washing machine usually displays various status information and error codes. If the display does not show anything or the display is abnormal, it may be that the display drive circuit of the main and secondary boards is faulty.
For example, when garbled characters or flickering appear on the display, you can try to restart the washing machine. If the problem persists, it may be that the display chip or related circuit on the main and sub-boards is faulty. In addition, if an error code is displayed on the display, the corresponding fault cause can be found according to the instruction manual of the washing machine, which can also help determine whether the main and sub-boards are faulty.
3. Use fault diagnosis tools
Some smart washing machines are equipped with fault diagnosis tools, which can read the fault code and operating status information of the washing machine by connecting to a computer or mobile phone. These tools can help users more accurately determine whether the main and sub-boards are faulty.
For example, using professional washing machine fault diagnosis software, you can read the sensor data, motor operating status and other information of the washing machine to determine whether the main and sub-boards are working properly. If the diagnostic software shows that there is a fault in the main and sub-boards, it can also provide specific fault codes and solutions to facilitate user maintenance.
4. Check the appearance of the main and sub-boards
In some cases, you can check the appearance of the main and sub-boards to determine whether there is a fault. If there are obvious signs of burning, capacitor bulging, component shedding, etc. on the main and sub-boards, it is likely that the main and sub-boards are faulty.
For example, when the washing machine smells or smokes, stop using it immediately and check the appearance of the main and secondary boards. If you find signs of burning on the main and secondary boards, you should contact professional maintenance personnel for repair in time to avoid causing greater losses.
In short, judging whether the Smart Washing Machine Main And Secondary Boards is faulty requires comprehensive consideration of factors such as the operating status of the washing machine, the display status, the use of fault diagnosis tools, and the appearance of the main and secondary boards. When judging the fault, you should operate with caution to avoid unnecessary losses due to misjudgment. If you are not sure whether the main and secondary boards are faulty, it is best to contact professional maintenance personnel for inspection and repair.
