General Wear and Tear
Whether your drain pump is clogged, the lid switch has ceased to function, or one of your washer’s belts has suffered damage, these issues can cause problems with the spin and agitation functions of your washing machine. Even poor selection of the settings on your timer or settings knob can result in trouble with agitation and spinning.
In addition to the issues mentioned above, there’s more. Pulleys in your washing machine are another component that can fail, causing your belts to break. Make sure if you replace a belt that the pulleys don’t need replacement as well.
Your washing machine’s motor is what makes the basket spin and agitate. So, if there’s a problem with the motor, you’ll have a problem with spinning and agitation. Sometimes motors can be repaired by replacing specific parts. However, other times, the entire motor must be replaced.
