Washing machines are one of the most essential home appliances we use in our day-to-day life. The motor is a vital component that drives the washing machine to complete its washing cycle. The motor wiring diagram is a crucial aspect that every user should know to troubleshoot the motor’s problem. In this journal article, we will discuss the 9 wire washing machine motor wiring diagram in detail to help you understand how to connect the wires properly by yourself.
What is a Washing Machine Motor Wiring Diagram?
A washing machine motor wiring diagram is a schematic diagram that depicts the connection between the washing machine’s motor, capacitor, and various switches. The wiring diagram helps repair technicians to troubleshoot and diagnose motor problems. It helps users to understand the motor’s functioning and helps them connect the wires properly during installation.
The motor wiring diagram comprises a set of instructions that directs how to connect the motor’s wires accurately. If you don’t follow the diagram, you may end up damaging your motor, which can lead to costly repairs. Therefore, it’s crucial to understand the wiring diagram before starting the installation or repair process.
Types of Washing Machine Motors
Before discussing the 9 wire washing machine motor wiring diagram, let’s take a look at the types of washing machine motors available in the market. There are two types of washing machine motors:
1. Single-phase Washing Machine Motor
A single-phase washing machine motor consists of two windings: the main winding and the auxiliary winding. The main winding generates a rotating magnetic field, while the auxiliary winding generates a starting torque. The washing machine motor with a single phase is commonly used in most home appliances, including washing machines, refrigerators, and air conditioners.
2. Three-phase Washing Machine Motor
A three-phase washing machine motor consists of three windings: the main winding, starting winding, and the running winding. The main winding generates a rotating magnetic field, while the starting and running winding generates a starting torque and keeps the motor running, respectively. A three-phase motor is widely used in industrial washing machines due to its high efficiency and low maintenance.

9 Wire Washing Machine Motor Wiring Diagram Explanation
Let’s have a detailed look at each wire’s functionality connected with different switches and components of the washing machine motor.
1. Red Wire (Main Winding #1)
The red wire is connected to the first main winding of the motor. The main winding provides a rotating magnetic field to drive the washing machine’s motor. The magnetic field is generated by passing an alternating current through the winding.
2. Blue Wire (Main Winding #2)
The blue wire is connected to the second main winding of the motor. The second winding provides the necessary magnetic field to maintain the motor’s rotating motion. It also helps to start the motor by providing the required torque to overcome the initial resistance.
3. Yellow Wire (Auxiliary Winding #1)
The yellow wire is connected to the first auxiliary winding of the motor. The auxiliary winding generates a starting torque to the motor, which helps the motor to start rotating. Once the motor starts, the auxiliary winding switches off, and the main winding takes over the magnetic field to drive the motor.
4. Pink Wire (Auxiliary Winding #2)
The pink wire is connected to the second auxiliary winding of the motor. It works similar to the first auxiliary winding and generates an additional starting torque to the motor.
5. Black Wire (Capacitor #1)
The black wire is connected to the first capacitor of the washing machine motor. The capacitor stores electrical energy and releases it to the motor to start rotating. It also helps the motor change its direction of rotation in some washing machines.
6. Green Wire (Capacitor #2)
The green wire is connected to the second capacitor of the washing machine motor. It provides the necessary power to the motor for its smooth functioning.
7. White Wire (Capacitor #3)
The white wire is connected to the third capacitor of the washing machine motor. It provides extra energy to the motor during high load conditions, such as when the washing machine is overloaded with clothes.
8. Grey Wire (Inlet and Outlet Valves)
The grey wire is connected to the inlet and outlet valves of the washing machine. These valves control the water flow into and out of the washing machine. The wire helps open and close the valves according to the washing machine’s cycle.
9. Brown Wire (Motor Start Switch #1)
The brown wire is connected to the motor start switch of the washing machine. The switch helps to turn on and off the motor during its functioning.
FAQs
Q. How do I know if my washing machine motor is faulty?
If your washing machine motor is faulty, you may encounter the following problems:
- The washing machine doesn’t start or take an extended period to start.
- The motor produces a loud noise or a burning smell.
- The washing machine drum doesn’t rotate properly, or it doesn’t rotate at all.
- The washing machine vibrates excessively or moves around during its functioning.
Q. Can I replace the washing machine motor by myself?
Replacing the washing machine motor is a complicated process that requires technical knowledge of motor wiring and switching. If you don’t have sufficient knowledge, it’s better to seek professional help to avoid any mishap.
Q. What should I do if I don’t have the motor wiring diagram?
If you don’t have the motor wiring diagram, you may consult the washing machine’s user manual, contact the manufacturer or seek professional help to get the required information.
Q. Can I connect the wires according to my preference instead of the wiring diagram’s instructions?
No, you should never connect the wires according to your preference instead of the wiring diagram’s instructions. The wiring diagram provides the correct connection sequence to ensure the motor’s proper functioning. If you connect the wires improperly, it may damage your motor and other electrical appliances connected to it.
Conclusion
A washing machine motor wiring diagram is an essential aspect that every user should know to troubleshoot and repair their washing machine motor. The 9 wire washing machine motor wiring diagram is a common type of motor used in today’s washing machines. The wiring diagram provides instructions to connect the wires with different switches and components to ensure the motor’s proper functioning. Always follow the wiring diagram’s instructions to avoid any damage to the motor or other electrical appliances.
