Always verify compatibility with your specific washing machine model before installation.

4. Installation Instructions

WARNING: Before attempting any repairs, always disconnect your washing machine from the power supply to prevent electric shock. It is recommended to consult a qualified technician if you are unsure about any steps.

1. Preparation: Ensure the washing machine is unplugged and the water supply is turned off. Move the machine to an area with sufficient space to work.
2. Access the Motor: Depending on your washing machine model, you may need to remove the back panel or tilt the machine to access the motor assembly. Refer to your washing machine's specific service manual for detailed access instructions.
3. Locate the Old Sensor: The Hall sensor is typically located near the motor's rotor, often attached to the stator assembly. It will have electrical wires connected to it.
4. Disconnect Wiring: Carefully disconnect the electrical connector from the old sensor. Note the orientation of the connector if it's not keyed.
5. Remove Old Sensor: Unfasten any screws or clips holding the old sensor in place and carefully remove it from the motor assembly.
6. Install New Sensor: Position the new GruDawu 6501KW2002A 6501KW2002B sensor in the same location and orientation as the old one. Secure it with the original screws or clips.

Figure 3: The Hall sensor correctly installed within the washing machine motor. Observe the secure fit and electrical connection.
7. Connect Wiring: Reconnect the electrical connector to the new sensor, ensuring a firm and proper connection.


Figure 4: Demonstrates the process of installing the sensor into the motor assembly. Ensure proper alignment and seating.

8. Reassemble: Reattach any panels or components that were removed to access the motor.
9. Test: Plug the washing machine back into the power supply and turn on the water. Run a short test cycle to ensure the machine operates correctly and the previous error symptoms are resolved.

5. Operating Principles

The Hall sensor works by detecting changes in a magnetic field. As the washing machine's motor rotor spins, magnets attached to it pass by the stationary Hall sensor. The sensor generates electrical pulses corresponding to the rotor's position and speed. This data is then sent to the washing machine's main control board, which uses it to precisely control the motor's operation, including agitation, spinning, and braking, ensuring optimal washing performance and preventing damage to clothes.

6. Maintenance

The GruDawu 6501KW2002A 6501KW2002B Motor Hall Sensor is a sealed electronic component and generally requires no routine maintenance. Ensure that its electrical connections remain clean and secure. Avoid exposing the sensor to excessive moisture or physical impact, which could lead to damage.

7. Troubleshooting

A faulty motor Hall sensor can cause various washing machine malfunctions. Replacing the sensor may resolve the following common issues:

• Washing machine does not tumble or agitate.
• Washing machine does not start.
• Washing machine spins slowly or erratically.
• Displaying "EO" error code (often related to motor issues).
• Displaying "LE" error code (Locked Rotor Error).

If these issues persist after replacing the sensor, further diagnosis by a qualified technician may be required to identify other potential problems with the washing machine's motor or control system.
