My washing machine won't spin
1. It won't pump or spin ? If your washing machine won't pump water or spin, first check to see if the motor is running. If the motor is running you need to check the pump pulley and the pump belt. To check the pulley, remove the pump from the washing machine and try to turn the pulley manually. If it is stiff, stuck, or frozen in place you will need to replace the pump. If the pump belt looks broken or worn then you need to replace it. Make sure to check the pump pulley even if the pump belt looks broken or worn. Many times they may both be faulty.
2. It pumps but it won't spin ? If your washing machine will pump water but it won't spin check for these following problems.
The lid switch may be defective. If your lid switch is malfunctioning then your washer can't spin and probably won't function at all. The switch is inside the washing machine main housing near the frame of the washing machine door. You will have to raise or open the top front of the washing machine to get to the switch. If the switch is defective then replace it. Some machines have a special fuse near the lid switch inside the control panel. If this fuse fails the washing machine will not fill until you replace it.
The motor coupler may be faulty or broken. Many washing machines use a small, inexpensive motor coupling. It is made of plastic and rubber and is mounted to one side of the shaft of the motor and the other side of the coupling is mounted to the transmission. Over time this coupling will wear and break. A belt may also be broken. Some washing machines have either one or two belts. If a belt is worn or broken you need to replace it.
Another problem with machines that pump but won't spin is that the clutch might be worn or broken. This is common on GE washers. GE washers use a clutch to regulate the proper spin speed. As the clutch wears out it won't be able to regulate the speed properly or it may not spin at all. If the clutch is worn or broken you need to replace it.
Another reason for this problem is that the drive motor may be faulty. Some washing machines use a motor to drive the spin. Run the motor in one direction and the washing machine will spin, run it in the other direction and the washing machine will agitate and/or drain. It is possible for a motor to operate normally in one direction but be faulty in the other direction. If this happens you need to replace the motor.
Another possible reason for this problem is that the transmission may be not be shifting correctly. Older washing machines have a transmission with an electric/mechanical shifting mechanism. If the shifting mechanism becomes worn or broken then the machine may drain the water but not spin. If this is the problem then you need to replace the shifting mechanism.
A final reason for this problem is that the spin bearing or the basket drive may be worn or broken. These components allow the inner tub to spin inside the outer tub. When this is the issue you will usually hear a loud banging or grinding sound during the spin cycle and the components will have to be replaced.
3) it'spins only when the lid is closed ? Washing machines are made with a safety switch and causes the spinning action of the machine to stop when the lid is opened. If your machine is doing this then don't worry, nothing is wrong.
