1. Turn off power to the washer at the circuit breaker to ensure complete power disconnection.
2. Close the water supply valves (hot and cold) to prevent water leakage during the repair.
3. Unplug the washer from the wall outlet for additional safety.
4. Verify power is off by attempting to turn on the washer. The washer should not respond.
5. Move the washer away from the wall to provide access to the back and sides of the cabinet.
6. Take multiple photos of the washer cabinet, mode shifter location, mounting, all mechanical connections, and linkage positions before disassembly. Document from multiple angles. This is absolutely critical for proper reassembly. Use a camera or smartphone to capture high-quality images.
7. Create a detailed assembly map by photographing the mode shifter connection points, including the drive shaft connection, actuator arm position, spring locations, mounting bracket, and linkages. Use masking tape to label key reference points.
8. Remove the washer cabinet by locating and removing the screws securing the top panel and front panel (typically 4-8 screws on the top and 4-8 screws on the front).
9. Lift the top panel upward and tilt it back to access the interior of the washer. Some models require disconnecting the lid switch connector before removing the top panel.
10. Remove the front panel by releasing the clips or removing the screws securing it to the cabinet frame. Carefully pull the front panel forward and set it aside.
11. Locate the mode shifter assembly (typically mounted on the transmission or drive system near the bottom of the washer, accessible from the front or side).
12. Take additional detailed photos of the mode shifter assembly, all mechanical connections, spring positions, actuator arm orientation, and linkage connections before disassembly.
13. Disconnect the actuator linkage from the mode shifter by releasing the clip or removing the pin connecting the linkage to the actuator arm. Note the exact position and orientation.
14. Remove the mounting bracket screws securing the mode shifter assembly to the transmission or washer frame (typically 2-4 mounting screws or bolts).
15. Carefully remove the old mode shifter assembly from the washer and place it on a clean work surface with adequate space for inspection.
16. Inspect the old mode shifter for visible damage such as a bent or broken actuator arm, worn or broken clutch components, broken or weakened springs, worn drive shaft splines, cracked or broken plastic mounting bracket, or seized linkages. This confirms the diagnosis.
17. Inspect the transmission drive shaft and mounting area for damage, corrosion, or worn splines. The shaft should be intact with clear, undamaged splines. If the shaft is damaged or worn, it may need replacement.
18. Clean the transmission mounting area thoroughly with a dry cloth to remove any debris, lint, or corrosion. Ensure the mounting surface is clean and dry.
19. Unpack the new WW02F00671 mode shifter assembly from its packaging. Handle carefully to avoid damaging the actuator arm, springs, or clutch mechanism.
20. Verify the mode shifter specifications match the old assembly: overall dimensions approximately 6-8 inches x 3-4 inches, drive shaft length and spline pattern, actuator arm design and orientation, mounting bracket hole locations, spring positions.
21. Compare the new mode shifter to the old one to verify the dimensions, actuator arm design, drive shaft splines, mounting bracket, spring positions, and overall appearance match. Ensure you have the correct replacement part.
22. Inspect the new mode shifter for any damage or defects before installation. The assembly should be intact with no visible damage, bent components, or broken springs.
23. Position the new mode shifter assembly on the transmission or washer frame, aligning the drive shaft with the transmission shaft and the mounting bracket holes with the frame mounting points.
24. Install the mounting bracket screws or bolts to secure the mode shifter to the transmission or washer frame. Tighten firmly but do not overtighten, which can crack the mounting bracket or strip the threads.
25. Verify the mode shifter is securely mounted and does not wobble or shift when gently pressed.
26. Reconnect the actuator linkage to the mode shifter by inserting the pin or engaging the clip connecting the linkage to the actuator arm. Use your detailed photos to ensure correct linkage position and orientation.
27. Verify the actuator linkage is securely connected by gently tugging on it. The linkage should not pull off—it should be firmly connected.
28. Manually test the mode shifter operation by gently moving the actuator arm through its full range of motion. The mode shifter should move smoothly between agitate and spin positions without binding or resistance.
29. Verify the springs are properly positioned and provide appropriate tension for mode shifting. The springs should be intact and properly seated.
30. Reinstall the front panel by positioning it on the cabinet frame and securing it with the mounting screws or engaging the clips.
31. Reinstall the top panel by positioning it on the cabinet and securing it with the mounting screws. Reconnect the lid switch connector if it was disconnected.
32. Move the washer back into position and restore power at the circuit breaker.
33. Open the water supply valves (hot and cold).
34. Turn on the washer and set it to a short wash cycle (approximately 10-15 minutes).
35. Verify the washer agitates during the wash phase by observing the agitator rotation. The agitator should rotate back and forth smoothly without the wash basket spinning.
36. Verify the washer spins during the spin phase by observing the wash basket rotation. The wash basket should spin at high speed without the agitator moving independently.
37. Listen for unusual noises during mode transitions. The mode shifter should operate quietly without grinding, clicking, or squealing sounds.
38. Allow the washer to complete the full cycle to verify proper operation throughout the wash, rinse, and spin phases.
39. Test multiple wash cycles with different load sizes to verify the mode shifter operates properly under various conditions.
40. Monitor the washer for 24-48 hours to ensure the mode shifter operates properly without issues.

Safety Notes: Always turn off power and close the water supply valves before working on the washer to prevent electrical shock and water leakage. Handle mechanical components carefully to avoid damaging sensitive clutch mechanisms, springs, or actuator arms. Ensure the mode shifter is securely mounted and all linkages are properly connected before operating the washer. This repair requires advanced mechanical skills and careful attention to detail—most homeowners should hire a professional appliance repair technician for this repair.

1. Document all mechanical connections with detailed photos before disconnecting. Take high-quality photos of the motor drive connection, wash plate connection, spring positions, and retaining bolts from multiple angles. Create a detailed assembly map with labels for each connection point. This documentation is critical for ensuring correct reconnection and avoiding costly mistakes.
2. Verify the motor drive and wash plate are functioning properly before replacing the mode shifter assembly. Test the motor drive by manually rotating it to ensure smooth operation. Inspect the wash plate for damage or corrosion. A faulty motor drive or wash plate will cause the same symptoms as a failed mode shifter assembly.
3. Inspect the clutch teeth on both the motor drive and wash plate for wear or damage. Worn or stripped clutch teeth will prevent proper engagement with the new mode shifter assembly. If the clutch teeth are damaged, the motor drive or wash plate may need replacement.
4. Clean the motor drive and wash plate connection areas thoroughly before installing the new mode shifter assembly. Remove any lint, debris, corrosion, or residue from the connection areas. A clean connection ensures proper engagement and prevents premature wear on the new assembly.
5. Align the motor drive and wash plate connection points carefully before installing the new mode shifter assembly. Misaligned connections can cause grinding sounds, incomplete engagement, or mode shifter failure. Verify the connections are properly aligned before securing the assembly.
6. The mode shifter assembly must shift smoothly between agitate and spin modes without resistance. After installing the new assembly, manually rotate the motor drive to verify smooth mode shifting. The assembly should shift smoothly without grinding, clicking, or clunking sounds.
7. Verify all retaining bolts are tightened firmly but not overtightened. Loose bolts will allow the mode shifter assembly to shift during operation, causing grinding sounds or mechanical failure. Overtightened bolts can crack the assembly or strip bolt threads. Tighten until snug, then add approximately 1/4 turn for final tightening.
8. Test the mode shifter assembly immediately after installation to verify proper operation. Set the washer to a short wash cycle and observe the agitation and spin phases. The washer should agitate smoothly during the wash phase and spin smoothly during the spin phase without unusual sounds.
9. The mode shifter assembly controls the transition between agitate and spin modes automatically based on washer cycle timing. The assembly does not require manual adjustment or control. If the washer does not transition properly between modes, the mode shifter assembly, control board, or timing mechanism may be faulty.
10. This repair is cost-effective compared to washer replacement. The cost of mode shifter assembly replacement ($55-95) is far less than the cost of a new washer ($800-2,000+). Replace the mode shifter assembly promptly when failure is detected to prevent the need for expensive washer replacement and to restore effective laundry washing and water extraction performance.
