Note: [Example 1] No water is allowed. \x0d\\x0d\ Check whether the filter screen of the water inlet valve is blocked and whether the water inlet valve is damaged. After confirming that they are in good condition, measure the voltage of 220V at both ends of the solenoid valve with a multimeter AC voltage block, which proves that the fault lies in the solenoid valve itself. \x0d\ Measure the coil resistance of solenoid valve with electric hoist. The normal value should be 4.5 ~ 5. 1kω, and the measured resistance value is infinite, indicating that the coil of solenoid valve inlet valve is burnt out. Replace the inlet valve and troubleshoot. \x0d\\x0d\[ Example 2] The water keeps flowing. The water inlet of the washing machine has reached the rated water level, and the water inlet solenoid valve still does not stop the water inlet. \x0d\\x0d\ This situation is generally that the water level pressure switch is damaged, which can be judged by blowing and pressurizing. Disconnect the power supply; Remove the water level switch, blow air into the pressure switch through the air return pipe, and measure the resistance between the two lugs of the water level switch with a multimeter. When blowing, the resistance should be zero, and when not blowing, the resistance should be greater than10kΩ. \x0d\\x0d\ After inspection, the resistance value measured by this machine is always very large, and the action sound of the internal contact of the water level switch cannot be heard, indicating that the water level pressure switch is faulty. After replacing the water level pressure switch, troubleshoot. \x0d\\x0d\ [example 3] The pulsator does not rotate when washing. \ x0d \ x0d \ can automatically feed water after starting, indicating that the washing machine has been powered on. After reaching the predetermined water level, the water can be stopped, indicating that the water level detection switch is normal. When the impeller is rotated clockwise and counterclockwise by hand, the impeller cannot rotate. After disassembly and inspection, it was found that the planetary gear inside the clutch was stuck due to damage. After replacing the clutch, troubleshoot. \x0d\\x0d\ [example 4] When washing, the impeller does not change direction. \x0d\\x0d\ When the washing machine washes reversely, the clothes in the bucket can only rotate in one direction, and there is no step-by-step instruction on the program-controlled indicator on the panel, so the ticking of the electric contacts in the device can't be heard. Check the micromotor, and the DC internal resistance measured by multimeter R× 1k is about 20kΩ and 24kΩ, respectively, indicating that the micromotor winding is not damaged. Then pinch the pinion clockwise with two fingers, and the pinion does not rotate smoothly. It was found that two permanent magnet rotors of micromotor were broken, and the cracks were fixed firmly with universal glue, and the fault was eliminated. \x0d\\x0d\ [example 5] After the power supply is turned on, the indicator light turns on, the motor does not turn, and there is only a buzzing electromagnetic sound. \x0d\\x0d\ Put down the washing machine and remove the motor. Welding capacitor, measure the resistance of capacitor with multimeter R× 100. Connect the stylus to the capacitor, and the pointer pointing resistance is zero, indicating that the capacitor has broken down. Replace the capacitor and troubleshoot. \ x0d \ [x0d] n.6 The drainage is not smooth, even the water can't be discharged. \x0d\\x0d\ When the drain valve is removed, it is found that the tension spring of the valve core has broken, which makes it impossible to open the drain valve when the electromagnet is attracted, resulting in poor drainage or even failure to drain. Replace the tension spring of the valve core and troubleshoot ... If you need accessories or have questions, please contact us at QQ 1837.
