一则:接到朋友一台小天鹅XQB30-8AJ套缸全自动洗衣机,自述故障现象为水放满洗涤桶,电机不启动运转。经笔者一试,电脑面板显示正常,可以基本排除电脑板损坏的这一可能性,可能是电机或电机启动电路损坏,或者是水位开关失灵。本着先简后繁的原则,拆开经检查后,发现启动电容完好,却没有供电电压,故怀疑是水位开关损坏了。用导线故意短路,水位开关两端电机就转起来了,毛病找到了,可以确诊是水位开关损坏了 A: received a friend a Little Swan XQB30-8AJ sleeve automatic washing machine, readme phenomenon is full of water washing bucket, the motor does not start running. After a try, the computer panel shows normal, you can basically rule out the possibility of damage to the computer board may be motor or motor starting circuit damage, or the water level switch failure. Based on the principle of first simple and complex, after disassembling and checking, it is found that the starting capacitor is intact but there is no supply voltage, so it is suspected that the water level switch is damaged. With wire intentional short circuit, the water level switch at both ends of the motor turn up, the problems found, you can confirm the water level switch is damaged
