1. First, check whether the adjusting rod nut on the drain valve is loose, and whether the cable of the tractor is loose from the drain valve, so that the tractor cannot open the valve core of the drain valve, resulting in no drainage;
2. If the fixing nut is not loose or the cable is not loose, the tractor may be damaged and the valve core of the drain valve cannot be opened. At this time, the tractor will be replaced;
3. It is also possible that the drain valve is blocked by sundries or the drain hose is bent and deformed. At this point, first unscrew the cover of the drain valve and take out the sundries;
4. The gap between the drainage rod and the rubber valve becomes larger, as long as the gap between the drainage rod and the rubber valve is appropriately reduced.
5. The spring in the drain valve is too long or loses its elasticity. Just replace the inner spring.
6. The damping of the moving core of the drainage solenoid valve is too large or the suction force becomes smaller. Remove the rust and dirt from the electromagnet, or replace the drainage solenoid valve.
7. If the problem remains unresolved, the computer board may be damaged, so the computer board should be replaced.

Little Swan washing machine fault code daquan:
The fault code is E 10: the water level did not change for 3 minutes during the water inflow, and the fault was caused by overtime water inflow. Check whether the inlet valve-return pipe or seal is not firm-check whether the drain pipe is suspended.
The fault code is E 1 1: when the washing machine is started, timed, makes an error and the program ends, the water level in the bucket exceeds the overflow water level. The fault is caused by a large amount of residual water in the bucket. Check the water inlet valve, pump and computer board.
The fault code is E 12: the water level exceeds the overflow level, and the fault is caused by overflow protection, that is, the water inlet valve is broken and needs to be replaced.
The fault code is E20: There is no signal from the drainage pump on the computer board. The fault is caused by the improper connection of the drainage pump. Check the wiring of the drain pump.
The fault code is E2 1: the water level does not change for 3 minutes during drainage, and the fault is overtime drainage. Check whether the drain pump and filter are blocked and whether the drain pipe is blocked.
The fault code is E30: After the button of the washing machine is started, the computer board failed to lock the door for six times. The cause of the failure is that the door lock can't be locked. Check whether the door hook is closed in place and whether the door lock is locked.
The fault code is E3 1: the washing machine failed to unlock for 6 times. The cause of the failure is that the door lock can't be opened. Check the door lock.
The fault code is E33: the frequency of the water level sensor is not within the specified frequency range. The fault is caused by the fault of the water level sensor, so the water level sensor should be checked.
The fault code is E34: the temperature sensor is open. The fault reason is that the temperature sensor is faulty, so the temperature sensor should be checked.
The fault code is E35: the temperature sensor is short-circuited. The fault reason is that the temperature sensor is faulty, so the temperature sensor should be checked.
The fault code is E40: the fault reason is the error of E2PROM check code.
The fault code is E4 1: the fault reason is E2PROM connection error.
The fault code is E50: the line voltage exceeds 280V, and the fault is caused by high voltage protection, so it should be used after the voltage returns to normal.
The fault code is E60: the motor failed to start for three times, and the fault reason is that the motor does not turn when starting, so the motor and computer board should be checked.
The fault code is E6 1: the computer board cannot detect the speed feedback signal during the motor rotation. The cause of the failure is that there is no speed measuring signal. Check whether the motor speed feedback signal line falls off.
The fault code is E62: The fault is caused by abnormal speed measuring signal.
The fault code is E70: the key has been pressed for more than 20 seconds, and the fault reason is that the key is stuck. Check the key.
