Understanding the Problem
The NTW4516FW3 is a top-load consumer washer that commonly shows symptoms like not starting, not draining or spinning, excessive vibration/noise, or leaking. These symptoms usually trace to a few serviceable parts: lid switch, drain pump, water inlet valve, drive coupling/drive belt or motor, suspension components, and the control/timer. Below are step-by-step diagnostics and repairs organized by symptom so you can find and fix the likely fault. 1) Washer won't start or doesn't respond to controls 1.1 Preliminary checks: confirm the washer is plugged into a working outlet and that the household breaker/fuse hasn't tripped. Check the plug and cord for damage. 1.2 Lid switch: open/close the lid while attempting a spin or start. If the washer will only run with the lid held down, the lid switch is suspect. Test with a multimeter (continuity when lid closed) or replace the lid switch assembly. Replacement: unplug washer, remove control panel or cabinet top per your model, disconnect wiring harness, unscrew and swap the lid switch. 1.3 Control board/timer or touchpad: if the lid switch is good, check for water fill/no-clicks from control when starting cycles. Inspect control board for burned components or loose harnesses. Replace only after confirming other parts. 2) Washer won't fill or fills slowly 2.1 Water supply & hoses: make sure both hot and cold are fully open and inlet screens are not clogged. Disconnect hoses and inspect screens. 2.2 Water inlet valve: if supply is good but no/low fill, replace the inlet valve assembly. Test with multimeter for coil continuity before replacement. 3) Washer won't drain or spin 3.1 Drain pump & hose: check sink/drain line and the washer drain hose for kinks or clogs. Remove the drain hose from the pump and check for obstructions. Inspect and clean the pump and trap area. 3.2 Pump operation: run a drain/spin cycle and listen for the pump motor. If you don’t hear it, check for voltage at the pump during drain cycle (multimeter) — if voltage present and pump not running, replace pump. 3.3 Drive coupling / belt / motor: if the motor runs but the tub doesn't spin, the drive coupling (or belt on belt-drive models) is likely worn or broken. Replace the coupling or belt per your model instructions. 4) Excessive vibration or banging 4.1 Load balance: ensure loads are even and not overloaded. Run a small load to test. 4.2 Suspension/shock absorbers or counterweights: inspect suspension rods (top-load shock/springs) for wear or breakage and replace any broken shocks. Check for loose counterweights and fasten if needed. 4.3 Tub bearings/agitator: if there is a grinding or rumbling noise during spin, the gearcase or tub bearings may be failing — this is more involved and often requires replacement of the gearcase or whole washplate/agitator assembly. 5) Leaks 5.1 Hoses & clamps: inspect inlet hoses, drain hose, and internal hoses for cracks, loose clamps or splits and replace as needed. 5.2 Tub seal or pump leaks: locate leak source by running a short fill/drain with front panel off (if comfortable). If leak is at the pump, replace pump assembly. If at the tub seal/shaft area, gearcase replacement may be required. General step-by-step replacement example — Drain Pump - Tools: Phillips/flat screwdrivers, socket set, pliers, multimeter, bucket/towels. Unplug washer and turn off water. - Step 1: Move washer away from wall. Disconnect water hoses and unplug. - Step 2: Remove top or front access panel per model (usually remove a few screws and snap panels off). - Step 3: Locate drain pump (usually bottom front or bottom rear). Place a shallow pan under pump to catch water. - Step 4: Disconnect the electrical connectors from the pump and the inlet/discharge hoses (clamps may be spring or worm-gear type). Remove mounting screws and remove pump. - Step 5: Install new pump by reversing removal: secure mounting, reconnect hoses/clamps, reconnect electrical connectors, re-install panels, reconnect water and power. Run a drain cycle and check for leaks and proper operation. Safety note: Always unplug the washer and turn off water before working on it. Use caution when accessing internal components (sharp edges and springs). If you are uncomfortable performing electrical diagnostics or working with the gearbox, hire a qualified technician.
Common Symptoms
Washer won't start, won't fill, won't drain or spin, loud rumbling/vibration, water leaks during cycle.
Common Causes
- Failed lid switch or lid lock assembly
- Clogged or failed drain pump or drain hose
- Worn drive coupling, belt, or motor failure
- Faulty water inlet valve or clogged inlet screens
- Worn suspension/shocks or damaged tub/gearcase causing noise and leaks
- Faulty control board or timer

Helpful Repair Tip
To confirm the faulty part quickly: run a diagnostic/drain cycle and listen — no pump noise suggests a pump fault; motor humming but no spin suggests a broken coupling/belt; washer only runs with lid forced closed indicates a bad lid switch. Use a multimeter to verify continuity on suspected parts before replacing.
Frequently Asked Questions
How do I tell if the lid switch is bad?
Test visually and electrically: while the washer is unplugged, open the cabinet to access the lid switch. Check for broken plastic or a loose actuator. Use a multimeter set to continuity — with the lid closed (or the switch pressed), the switch should show continuity; when released, no continuity. If no continuity when closed, replace the lid switch assembly.
Can I repair the NTW4516FW3 myself or should I call a technician?
Many common repairs (replacing a drain pump, inlet valve, lid switch, drive belt or suspension shocks) are DIY-friendly if you have basic tools and follow safety steps (unplug, shut off water). Tasks involving the gearcase, motor mount or sealed tub bearings are more complex and heavier — if you lack tools, experience, or the correct replacement parts, calling a qualified appliance technician is recommended.
