To test a 3 wire washing machine motor, you will need to first disconnect the power supply to the washing machine. Once the power is disconnected, you will need to remove the motor from the washing machine. Once the motor is removed, you will need to connect one lead from your voltmeter to each of the three wires on the motor.
After all three leads are connected, you will need to turn on your voltmeter and set it to read in AC volts. The reading on your voltmeter should be between 0 and 5 volts. If it is not, then there may be a problem with your motor.
- Unplug the washing machine from the power outlet
- Remove the back panel of the washing machine to access the motor
- Use a multimeter to test for continuity between each of the three wires going to the motor
- There should be continuity between two of the wires and no continuity between the third wire and either of the other two wires
- If there is no continuity between any of the three wires, then the motor is most likely defective and will need to be replaced

How to test a 3 wire washing machine motor
How Do You Test a Motor With 3 Wires?
When testing a three-wire motor, you will need to use a multimeter set to the ohms setting. You will first want to test between each of the three wires and ground. This will tell you if there is continuity between the wire and ground.
If there is no continuity, then the wire is most likely broken. If there is continuity, then you will want to test between each of the pairs of wires. This will tell you if there are any shorts between the wires.
If there are no shorts, then the motor should be fine.
How Do You Test a Washer Motor With a Multimeter?
If your washing machine isn’t starting up, one issue you can check yourself is the washer motor. With a multimeter, you can test whether the motor is working and receiving power. This can help you diagnose the problem so you can either fix it yourself or know what to tell a repair person.
To test the washer motor with a multimeter, first make sure that the washing machine is unplugged. Then, open up the washing machine so you can access the motor. Locate the two terminals on the motor—these will be where you attach your multimeter leads.
Set your multimeter to Rx1, and touch one lead to each terminal on the washer motor. If there is continuity between the terminals, this means that the motor is working and receiving power. If there is no continuity, then either the motor is not getting power or it is defective and will need to be replaced.
How Do You Diagnose a Bad Washing Machine Motor?
If your washing machine is having problems starting up, it may be due to a bad motor. Here’s how you can diagnose the issue:
First, check to see if the motor is getting power.
If it’s not, then the problem is likely with the electrical supply to the machine.
Next, listen for any strange noises coming from the motor. If you hear grinding or humming noises, this could be a sign that the motor is going bad.
Finally, try to start up the washing machine with the lid open. If the motor starts but quickly shuts off again, this indicates that there is something wrong with the motor itself.
How Many Wires Does a Washing Machine Motor Have?
If you’re wondering how many wires your washing machine’s motor has, the answer is typically four. The four wires are what provide power to the motor and allow it to run. These wires are usually color-coded so that they’re easy to identify.
Red is usually for the live wire, black is for the neutral wire, green is for the earth wire, and blue is for the return wire.

How to Test Washing Machine Motor With Multimeter
If your washing machine isn’t starting, one of the first things you should check is the motor. The motor powers the whole machine, so if it’s not working, neither will your washer. Luckily, testing the motor is a pretty simple process that only requires a multimeter.
To test your washing machine motor with a multimeter, start by unplugging the machine and removing the rear panel. Once you have access to the motor, use your multimeter to test for continuity between the two main leads on the motor. If there is no continuity, this means that the motor is faulty and needs to be replaced.
If you don’t have a multimeter or are unsure of how to use one, you can also take your washing machine motor to a qualified technician or appliance repair person for testing and diagnosis.
Conclusion
To test a 3 wire washing machine motor, you will need a multimeter. First, disconnect the power to the washing machine. Next, remove the washing machine’s cabinet so you can access the motor.
Once you have access to the motor, use the multimeter to test each of the three wires for continuity. The black wire should show continuity with the white wire, and the red wire should show continuity with the green wire. If any of these tests fail, then there is a problem with the motor and it will need to be replaced.
