I was looking for solutions to your problem, and I came across AP Wagner
this is from their RepairCenter. There are a lot of possible solutions here, but you may find the answer you are looking for
Make sure the lid is closed. There is a switch inside that completes the connection. Your washer may not spin or agitate if this connection is not completed. Make sure that the speed selector switch is not between speeds. Verify that the washer is not in a soak cycle. You can also reset the water level up or down to make sure that the water level control switch isn't stuck. If you hear a humming sound when the washer is full of water, you may have something stuck in the drain pump.
If one of these is not the problem, check the belt. The main drive motor has two distinct functions. The first function is to spin the basket; the second function is to reciprocate your agitator. Inside your washer's transmission is a crank type gear and connecting rods that are used to agitate the washer, with the spinning coming from the washer motor itself. This usually entails some sort of clutch mechanism. Some things to check if your washer is not agitating and/or spinning are:
If you notice weak or no agitation, the splines connecting the agitator to the drive shaft may be stripped and need to be replaced.
After a lot of use, belts can become worn or damaged. Replace any worn or damaged belts immediately. If you have a broken belt, replace it and check the pulley to make sure it's not seized.
Sometimes the drive pulley can wear out and it won't turn the drive belt. Look for wear marks, pits, or uneven spots. It's best to just replace it with a new pulley.
Many washers use a reversing motor. Sometimes it will continue to work in one direction even if it won't spin in the other direction. If your washer has a drive motor issue, you probably need to replace the motor with a new one. Call a professional appliance repair person to verify this first.
The lid switch is a safety device that's there to protect you from sticking your hands into a spinning washer. If this switch goes bad, the washer will not work. You will have to replace it. It is inside the main housing for the washer, and located near the door frame.
The coupler connects the motor to the transmission. After lengthy use, this plastic and rubber coupler can wear out. If this happens, you need to replace it.
Transmission and clutch assemblies can cause agitator and spinning problems They are fairly complex, so if you suspect you have transmission or clutch issues it's probably in your best interest to call a professional appliance repair person.
I hope this helps! Have a nice holiday!
