Washing machines, like any other mechanical device, occasionally needs servicing. A common problem with an older washing machine is that the spinner, or agitator, stops rotating during wash cycles. Fortunately, most washing machine problems are easy to troubleshoot. Any do-it-yourselfer can fix it; here’s how.
Unplug the washing machine, and turn off the water supply to the machine. If necessary, remove the water hoses from the back of the washing machine because they may be in the way of the access panel.
Check that the agitator is seated correctly by opening the lid of the washing machine. If it's loose, pop off the top of the agitator--if there is one--and tighten the bolt that holds the agitator in place. Or, in some models, simply pull straight up and then reseat the agitator.
Remove the access panel located in the back of the washing machine by unscrewing the screws holding it in place. This allows access to the drive motor.
Press on the drive belt that works the agitator. If the belt moves more than 3/4 inch, tighten the belt to fix the spinner problem. If the belt is worn or cracked, replace the belt.
Replace the drive motor, if tightening or replacing the drive belt doesn't fix the agitator. Purchase a new drive motor at a wholesale retailer. Disconnect wiring, remove screws holding motor in place and insert new motor. Screw into place, and connect wiring.
Check for any black substance leaking under the washing machine. This might indicate a clutch problem, if the washing machine spinner is not working. Contact a professional repairman to replace the clutch.
