[Washing machine cannot be dehydrated]What should I do if the washing machine cannot be dehydrated? Troubleshooting of a double-cylinder washing machine
I. What is a double-cylinder washing machine
The double-cylinder washing machine is actually what we call a semi-automatic washing machine. One of its cylinders is used for rinsing clothes, and the other is used for dehydration, so it is called a double-cylinder washing machine. Because it requires manual operation in the middle of the cleaning process, it also becomes a semi-automatic washing machine. Most rural households now use semi-automatic washing machines.
Second, the reason why the double-cylinder washing machine is not dehydrating
1. The dehydration motor is faulty, the circuit is in poor contact, and there is a virtual connection The place.
The dehydration motor cannot work normally if the coil is burnt, disconnected, short circuit between phases, short circuit between turns, etc. The main reason for the damage to the motor coil is moisture, which is mostly caused by the damage of the water seal cup or the serious wear of the shaft sleeve, which causes water to leak into the motor coil.
2. Foreign objects are wrapped around the bottom of the outer wall of the dehydration tub
Some users do not place a plastic baffle above the clothes in the dehydration tub, and put socks, handkerchiefs and other small things on top of the clothes when dehydrating , When the dehydration bucket rotates at a high speed, the small things will be thrown into the bottom of the outer wall of the dehydration bucket from the gap between the top of the dehydration bucket and the end cover, and tightly wrapped around the shaft between the bottom and the water seal, making the motor unable to run.
3. Capacitor failure or reduced capacitance
A capacitor of about 4 microfarads is connected in series with the starting winding of the dewatering barrel motor to improve the starting characteristics of the motor. After the washing machine is powered on, the spin tub motor makes a “humming” sound and does not turn.
4. The shaft sleeve and the shaft of the dehydration motor are locked.
The lack of oil between the dehydration motor and the shaft sleeve, moisture and rust, etc., will cause the shaft and the shaft sleeve to lock. When the power is turned on, the shaft drives the bushing to form friction between the bowl and the pressing sheet of the bushing, so that the motor of the dehydration bucket rotates slowly or cannot be started. The damping spring of the dehydration motor is not elastic enough; the supporting foam on the wall of the dehydration cylinder falls off; the bearing of the dehydration motor is bad or damaged; the connecting screw of the dehydration cylinder and the dehydration motor is loose.
5. Timer failure.
Three, what to do if the double-cylinder washing machine does not dehydrate
1. If the dehydration motor is faulty or the circuit is in poor contact, you can use a multimeter to measure separately If the main and secondary windings have no resistance or the resistance becomes very small, it means that the motor coil is damaged. The water seal must be checked for this fault. If it is found that the water seal is damaged or the water seal shaft sleeve is seriously worn, it should be replaced one by one.
2. If there is a foreign body entangled at the bottom of the outer wall of the dewatering bucket, clear the foreign body and it can be used normally.
3. If the capacity of the capacitor decreases or fails, you can check whether the capacitor is invalid or replace it with a new product; if the motor starts and runs normally, it means that the fault is on the capacitor.
4. If the shaft sleeve and shaft of the dewatering motor are locked, the motor should be removed and repaired if the shaft is locked, and the fault can be eliminated after reassembly.
5. If the timer is faulty, open it for repair.
