The following Siemens washing machine after-sales service introduces several common washing machine does not dewatering causes and solutions.
/1, the washing in the washing in an unbalanced state
When too much clothing in the case of the washing can not be adjusted to the balance, then the washing machine will automatically adjust to the low speed, resulting in poor dehydration, if this is the reason why the washing machine can not be dehydrated, then you do not need to worry about it too much, you can be in the washing of clothes before the number of clothes to put a few less, do not all of a sudden! Do not stuff too much at once, so as not to cause an imbalance in the washing, which affects the dehydration effect.
2, the safety switch on the top cover of the washing machine is damaged
Washing machine in the dehydration process is a high-speed mechanical movement. Try not to open the top cover in the process of dehydration to avoid damage to the top linkage switch, if the top cover of the washing machine linkage switch damage, the washing machine can not be dewatering
3, washing machine drainage system blockage
When the washing machine drainage system blockage will result in the washing liquid in the water tank can not be discharged, when the water tank foam is too much, or the tank of the washing liquid is difficult to discharge, the water level switch can not be reset. When there is too much foam in the drum, or the washing liquid in the drum is difficult to be discharged for a while, the water level switch can not be reset, and the washing machine can not enter the dehydration program. Suggestion: Remove the drain filter, flush the drain opening with water and remove debris from the drain valve.
4, the water level switch can not be reset
Washing machine dehydration program is in the washing liquid drain, the water level switch reset conditions to start, if the water level switch is damaged, will not be able to enter the dehydration program!
The washing machine can not be dehydrated, it may be caused by human error, but it may also be the fault of the washing machine itself.
1, motor failure
If the washing machine machine machine failure caused by the washing machine can not be dehydrated, you can try to open the back cover of the washing machine, move the pulley by hand, if there is no stagnation phenomenon, turn on the power, the motor has a buzzing sound and does not rotate, it is the motor turn-to-turn short-circuit or damage, or capacitors are not connected to the motor circuit. At this time should cut off the power supply, remove the motor belt to restart. If the motor still does not turn or low speed, it is a motor failure, should be repaired or replaced motor.
2, solenoid valve damage
Automatic washing machine washing and dehydration is through the solenoid valve to convert the gear at the bottom to complete the solenoid valve damage will also make the dehydration can not operate properly!
3, motor plug loose
Because of the drum washing machine connecting wires are used to connectors, so in the transportation process, due to vibration and other reasons often cause the motor plug loose or inserts in the installation of the phenomenon of being out of the top. If the plug is loose, it should be re-inserted and tightened with a tie wire to prevent it from falling off again.
Three, washing machine after-sales service can not be heated, the heating indicator does not light the repair
This kind of failure, you should check the following parts:
1, check the thermostat plug end whether the contact is poor or broken wire. Rule out bad or broken wire points.
2, check whether the thermostat is disconnected. If the multimeter to measure the resistance value of infinity (normal 0) or rotating no switch sound, it means that the thermostat is damaged, need to replace the thermostat.
3. Check whether the plug and socket are in poor contact, whether the power cord is broken or whether the internal terminals are burnt. Repair or replace the wiring, plug and socket.
4, check whether the controller is damaged. There is power input no output to the heating tube, need to replace the controller.
In the insulation state, drain about 5min indicator to heating state is normal; normal hot water use, then the indicator is damaged, need to be replaced.
Four, after-sales service washing machine power indicator does not light, there is no hot water, but the leakage protection indicator light repair
Out of this kind of failure, the following parts should be examined:
1, check whether the thermostat has been opened. The thermostat temperature knob to the highest position (fixed temperature type without temperature knob).
2. Check whether the connecting wire inserts are loose or disconnected. Repair or re-insert the connection line.
3, check whether the working voltage of each component is normal (such as: AC250V with a multimeter to measure the power cord, the connecting line and components whether there is 220VI for the voltage). Repair or replace the damaged parts.
Five, washing machine after-sales service power indicator light, but no hot water repair
4, motor thermal protector action
Due to overload, blocking, etc., so that the motor heat, motor thermal protector action caused by the washing machine does not spin, this time, as long as to wait for the thermal protector reset can be used.
5, some models have a non-dehydration
First of all, you should check whether the non-dehydration button is pressed. If this key is pressed, the washing machine has an anti-wrinkle function and does not dehydrate the wash. As long as you lift the non-shedding button, the washer will spin.
6, computer control board failure
Can only be replaced, because its control board in order to waterproof is covered with glue, repair is quite inconvenient!
There are many reasons why the washing machine can not be dehydrated, if it is not man-made can not be dehydrated, it is recommended to contact a professional maintenance personnel to overhaul.
The motor in a drum washing machine is often a two-speed motor, known as a capacitor-run two-speed motor. The motor is equipped with two sets of internal windings, the same stator core, respectively, 12-pole low-speed windings and 2-pole high-speed windings. In the washing process, the 2-pole low-speed winding works to drive the drum to wash the clothes; in the dewatering process, the 12-pole high-speed winding works to drive the drum to run at high speed to throw out the water in the clothes.
Siemens washing machine after-sales maintenance special reminder:
Motor winding in the main and secondary winding control motor positive and negative rotation, so have the same wire diameter, number of turns, pole distance and pitch. The wire diameter, number of turns, pole pitch, and pitch of the male *** winding are different from those of the main and secondary windings, and it is star coupled with 120 degrees between adjacent windings.
Dewatering when the washing machine can only run in one direction, so the main and secondary winding of the dehydration winding has a clear difference, the main winding of the wire diameter thick, the number of turns, DC resistance is small, the secondary winding of the wire, diameter fine, the number of turns, DC resistance is large.
Two sets of motor windings are connected together to form the male **** end of a two-speed motor. When power is supplied to the washing winding (12-pole low-speed winding), the washing machine runs the drum at low speed for washing, and when power is supplied to the spinning winding (2-pole high-speed winding), the drum runs at high speed for spinning. The power supply to the motor is controlled by the control circuit board, which interlocks the two sets of motor windings and does not allow the two sets of motor windings to be energized at the same time.
