Finding out that your washing machine agitator is no longer working can be a real headache. Not only is it inconvenient, but it can also be expensive to fix. However, before you call a repairman, there are a few things you can do to try to fix the agitator yourself. In this article, we will provide you with step-by-step instructions on how to fix a washing machine agitator. We will also provide you with some troubleshooting tips in case the problem persists.
One of the most common causes of a washing machine agitator not working is a broken drive shaft. The drive shaft is the part that connects the agitator to the motor. If the drive shaft is broken, the agitator will not be able to turn. To fix a broken drive shaft, you will need to replace it. You can purchase a new drive shaft at most hardware stores. Once you have the new drive shaft, you will need to remove the old one. To do this, you will need to remove the agitator. Once the agitator is removed, you will be able to access the drive shaft. To remove the drive shaft, you will need to use a wrench to loosen the nut that holds it in place. Once the nut is loose, you will be able to pull the drive shaft out of the agitator. To install the new drive shaft, simply insert it into the agitator and tighten the nut. Once the new drive shaft is installed, you will be able to reassemble the agitator and put it back in the washing machine.
If replacing the drive shaft does not fix the problem, there may be another issue with the washing machine. One possibility is that the motor is not working properly. To test the motor, you will need to use a multimeter to check for continuity. If there is no continuity, the motor will need to be replaced. Another possibility is that the transmission is not working properly. To test the transmission, you will need to remove the agitator and spin the transmission by hand. If the transmission does not spin freely, it will need to be replaced.
Troubleshooting Common Agitator Issues
Loud Noises During Agitation
Pinpoint the source of the noise by listening carefully. Common causes include loose agitator dogs, worn-out transmission gears, or a faulty motor. Here’s a detailed investigation guide:
