These tips are very useful when repairing Panasonic washing machines!

As a frequently used appliance in the home, it is normal for washing machines to malfunction. Washing machines of many brands such as Panasonic may also have problems due to long use. Last month, Hong Kong Junhong Electrical Appliance Repair Center received two repair cases of Panasonic washing machines. Because the faults were failure to start and abnormal drainage, it was a good time to introduce practical tips for repairing Panasonic washing machines.

1. How to troubleshoot and maintain the washing machine if it does not start?

If you encounter a situation where the washing machine does not start during daily use, you must first check whether the power supply is normal, and then cut off the power to troubleshoot the problem. For example, the technician dispatched by Hong Kong Junhong Electrical Appliance Repair Center encountered a Panasonic NA-F80S6 washing machine does not start. The troubleshooting and maintenance procedures are as follows:

(1) Check whether the power cord is powered on normally. After confirming it is correct, disassemble the casing on the control panel and measure the control motherboard with a multimeter. If the multimeter displays normal, it means there is no abnormality in the motherboard circuit.

(2) Then disassemble the casing of the motor set and use an external meter to detect the resistance of the motor coil. If the resistance value is abnormal, it means the motor is burned out. If it is normal, continue to check and determine whether the motor is stuck by foreign matter.

(3) Check the leakage protection device of the washing machine. Today's washing machines are very smart. If the motherboard temperature is too high or other problems, the power will be automatically cut off for protection. In this way, you can find out the reason why the washing machine is not running.

2. The washing machine does not drain water

The Panasonic washing machine I encountered before did not drain water because the motherboard was abnormal. At the same time, the fault code displayed on the screen was E01, so the technicians were very efficient in troubleshooting. In another case, E01 was also displayed, and the fault was that it did not drain water. Regarding this, we There is also a troubleshooting process.

(1) If there is no drainage, cut off the power and manually open the drain valve. First, empty the clothes and water in the washing tub, then check and then use a multimeter to test the power cord and other lines.

(2) If there is no problem with the line, check the drain pipes and valves. If these parts have not been cleaned regularly, the drain pipes and valves may be blocked, and professional cleaners need to be used to clear them.

(3) Another reason is that there is a problem with the control motherboard. The problem can only be solved by replacing the motherboard. If the washing machine itself does not start but there is a screen display, you can refer to the fault code to troubleshoot, which can greatly improve maintenance. efficiency.

The above is the experience that you can refer to when repairing Panasonic washing machines. The same is true for repairing washing machines of other brands. Also, it should be noted that drainage failure of washing machines is usually caused by a failure of the control motherboard, which is often related to the owner's usage habits. Do not do it manually after presetting the automatic mode. Intervening in the drainage of the washing machine may seem to save water, but in fact it can easily cause the washing machine control motherboard to malfunction.
