Understanding the Problem
Brief explanation: The "actuator" on a GTW335ASN0WW top‑load washer usually refers to the shift actuator (sometimes called the shifter or shift assembly) that moves the transmission/gearcase between agitate and spin. When it fails the washer may not shift, may stay stuck in agitate or spin, or make grinding/clicking noises. Replacing the actuator typically restores normal shifting. Step-by-step diagnostic and repair steps: 1. Confirm the symptom: Run a cycle and note whether the machine fails to shift from agitate to spin, remains stuck in one mode, makes loud grinding noises when changing mode, or shows error codes. If the washer won’t spin but drains, suspect the actuator/shift assembly or gearcase. 2. Check for simple issues first: Make sure load is balanced, the lid latch is working, and there are no obstructions under the tub. A jammed basket or foreign object can mimic actuator failure. 3. Enter diagnostics/service mode: For GTW series washers, use the service/test mode to command an agitate and spin cycle. Listen and watch for the actuator moving. If the motor runs but the transmission doesn't shift, the actuator/shift assembly is likely bad. 4. Listen & observe: A healthy actuator should move with a distinct shifting sound. If you hear repeated clicking, grinding, or the actuator motor hums with no shift, the actuator or internal shifter folding tabs are likely damaged. 5. Check electrical connections: Unplug the washer. Remove the rear access panel or console (see service manual) and inspect the actuator harness and connectors for burn marks, corrosion, or loose pins. Re-seat the connector and inspect wiring to the main control board. 6. Test for power at the actuator: With the washer plugged in and in a commanded shift (use diagnostics), measure voltage at the actuator connector. No voltage while in the correct test step suggests a control board/board harness issue; voltage present but no movement suggests a bad actuator. 7. Mechanical inspection: Remove the actuator and inspect the plastic drive tabs, linkages, and splines for wear, broken teeth, or stripped gears. Many failures are mechanical rather than electrical. 8. Replace the actuator: If testing and inspection indicate the actuator is faulty, replace it. Typical basic replacement steps are below. Basic replacement (general steps, verify with your model manual): 1) Unplug the washer and move it away from the wall. Turn off water if you will remove the cabinet or need extra access. 2) Remove the control console or rear access panel per the service manual to access the actuator area (on many GTW models the actuator is behind the console or at the rear of the transmission). Keep track of screws and wire locations. 3) Disconnect the actuator wiring harness and any linkage attached to it. Take photos to aid reassembly. 4) Unbolt and remove the old actuator assembly. Inspect the surrounding transmission area for damage or metal/foreign objects. 5) Install the new actuator in the same orientation. Reattach bolts, linkages, and wiring harness. 6) Reassemble the panel/console, restore power, and run a test cycle to confirm shifting and normal operation. 7) If the washer still fails to shift after installing a known-good actuator, suspect the main control board or wiring harness—further testing needed. Safety note: Always unplug the washer before accessing internal components. If you are not comfortable working with electrical components and moving heavy panels, hire a qualified appliance technician. Use proper tools and keep hands clear of sharp sheet metal and the drive system.
Common Symptoms
Washer won’t shift from agitate to spin; stuck in agitate or spin; loud grinding or clicking during mode changes; washer runs but clothes stay wet; unusual noises from the transmission area.
Common Causes
- Mechanical wear or broken plastic shift tabs inside the actuator
- Failed actuator motor or internal gears
- Faulty wiring or connector between the actuator and control board
- Defective main control board not sending shift command

Helpful Repair Tip
Run the washer in diagnostic mode and watch/feel for actuator movement while measuring voltage at the actuator connector—voltage present but no movement means the actuator is bad; no voltage points to a control or wiring issue.
Frequently Asked Questions
How much does replacing the actuator on a GTW335ASN0WW cost?
Parts-only: a new shift actuator typically ranges from about $40 to $150 depending on OEM vs aftermarket and vendor. Labor varies by region—expect 1–2 hours for a technician. Total pro replacement cost commonly runs $120–$300. Always confirm exact part pricing for GTW335ASN0WW before ordering.
Can I run the washer without the actuator or temporarily bypass it?
No—bypassing the actuator is not recommended. The actuator controls mechanical shifting between agitate and spin; running without it can damage the transmission and cause unsafe operation. Temporary workarounds risk further damage; replace the faulty actuator with the correct part for reliable, safe operation.
